Help! My Weed Seeds Are Not Germinating

Germinating weed seeds. It’s not a difficult task as such because in almost all cases it works in one go. Sometimes, though, there are a couple that don’t want to germinate and naturally you‘d like to know why. And guess what? Very often the problem has a completely logical cause. There are lots of factors that can result in weed seeds not germinating. Are you too experiencing these problems? This blog examines the commonest problems and provides tips for helping germination in the best way.

Germinating a seed. At first sight it seems so simple. And in most cases everything goes well. Even so, it occasionally happens that customers come back to us about a seed that wouldn’t germinate. We then try to figure out the cause and help out our customers. Apart from that, we want to properly inform everyone and prevent the same mistake from being made twice. So, read this blog carefully to make sure that you do everything correctly and don’t waste any expensive weed seeds.

Cheat Sheet for Germinating Weed Seeds

  1. Use a germination tray or coffee filter and keep away from sunlight.
  2. Make and keep weed seeds moist throughout the entire germination process.
  3. For germinating weed seeds use mineral water with the correct pH.
  4. Germination takes a maximum of one week. Usually 2-4 days.
  5. Germinated? Always plant root downwards.
  6. Storing seeds? Can be stored for a good 10 years if kept cool and airtight. Otherwise for a maximum of 6 months.

Germinating Weed Seeds in Various Ways

Weed seeds can be germinated in all kinds of ways. In a cup of water, between cotton pads, in a coffee filter or directly in the ground. Everyone has their preferred method. But it’s important to know that some methods are more effective than others. In any event, we recommend you to first germinate the weed seed before planting it in the soil. This method gives you the most chance of success. Moreover, this gives you the most influence over the germination process. This is far less the case when you put the seed directly into the soil.

Make sure there is a root coming out of the weed seed before putting it in the soil

Why Weed Seeds Don’t Germinate

Weed seeds should germinate in 95% of cases. They are of course natural products and it can sometimes happen therefore that you get one that doesn’t want to come out of its shell. But if several weed seeds fail to germinate then there is something wrong with the conditions under which you are trying to germinate the seeds. We list all the possible causes below. Read through them carefully and see whether one of these factors might apply in your case.

Temperature and Humidity

– Temperature and humidity are probably the key factors in the germination of weed seeds. They need warmth and a high humidity to be able to come out of their shell. Ensure a temperature of at least 20 degrees. The humidity must also be high.

+ The ideal temperature for germinating weed seeds is around 22 to 25 degrees Celsius. To maintain high humidity we recommend you place the dampened germination tray or coffee filter in an airtight Zip Lock bag. It’s worth investing in a humidity and temperature meter to keep a close eye on everything.

Tip: do you want to be assured that the conditions are always right? If so then germinate the weed seeds in a Propagator! This container ensures the correct temperature, humidity and light.

Water and pH Value

– Germinating weed seeds involves working with water. It’s important for the water you use to have the right pH value (acidity). The seeds are very sensitive to this. A good pH value for germinating weed seeds is 6.0. So don’t use rain water or tap water. This may have a pH value of 8.0 or higher.

+ It’s best to use mineral water for germinating weed seeds. But please note: not every brand has the same pH value. In the Netherlands, for example, you can use Spa Blauw. This has a favourable pH value of around 6.0. Check the packaging to see whether the pH value is stated.

Amount of Water

– Moisture is very important for germinating seeds but you shouldn’t overdo it. Too much moisture is not good for the seeds and can reduce their germinability.

+ Sometimes we are sent photos of germination trays or filters that are completely filled with water. This is not the idea. Make pads, filters or trays nice and wet but never allow the seeds to be completely under water. Certainly don’t put them in a glass of water for a couple of days.

Sun and Light

– Weed seeds are averse to direct sunlight. Light is not necessary at all for germinating seeds. Just think – roots grow under the ground. In the absence of sunlight. So don’t lay the seeds uncovered on the window sill or next to the window.

+ It’s best to put your weed seeds in a warm, dark place. For example, in the cupboard next to the central heating boiler, or on your TV cabinet in the living room (out of direct sunlight).

Storage

– Are you working with older weed seeds? These are quite capable of germinating but what’s important is that they were stored in the right way. Weed seeds should be stored airtight and in the refrigerator. If you don’t do this then the seeds are viable for about 6 months. Thereafter the germinability is reduced and they might no longer sprout.

+ Store weed seeds in the refrigerator at a temperature of between 3 and 7 degrees Celsius. Ensure that no moisture is present as otherwise germinability can be reduced. Fortunately, airtight often means watertight as well. Kept in this way the seeds can remain viable for up to 10 years!

Wrong Medium

– Are you germinating your weed seeds by placing them directly into the medium? If so then it’s very important to use the right medium and for it to be in optimum condition. Use soil for cuttings instead of soil with additives. It shouldn’t contain too many nutrients. In addition, the humidity needs to be right with not too low a temperature. Mould and pests are also dangerous and increase the chances of failure. Besides all that, you cannot determine in advance that the root will be pointing downwards when the seed does sprout. Briefly put, there is plenty that can go wrong if you plant directly into the soil or another growing medium.

+ Are you nevertheless still planning to plant the seed directly into the soil? If so then ensure mould-free soil for cuttings, temperatures above 20 degrees, lots of sunlight on the medium, high humidity and the right pH value (6.0 – 6.5). But please note: as stated earlier, the germination percentage is usually lower with this method. You can’t see what is happening and once you’ve placed the seed in the soil you have no further influence over it. We therefore strongly recommend you don’t use this method.

Wrong Way Up in the Soil

– Have you got the weed seed to germinate and are now looking to put it in the soil? It’s important then for the root to be the pointing the right way. Some people think that this little thing has to grow upwards. But this is not the case. That little thing is the root which always germinates first. Point this tiny root downwards when you plant the seed in the soil.

With the root downwards in the soil

Don’t place the seed directly into the soil for germination. Although purely natural, the chance of your plant emerging is considerably less than when you follow our instructions.

Patience is a Virtue

– We often get messages from people who have given up hope after a few days. Be patient! Generally speaking, weed seeds take 2 to 4 days to germinate. But it can happen that seeds take a week for this. Are you still putting them directly into the soil, despite our warnings? If so then it can take a good 2 weeks for your seedling to emerge above ground.

+ Therefore it’s important to have patience. With the coffee filter or propagation tray methods wait a maximum of 7 days. If there’s still no sign then check whether the environment meets the above-mentioned factors, otherwise get in touch with our customer service.

Tip: don’t open the filter or the container every day to take a peek. Leave the seed alone to do its stuff. Too much messing around will reduce the germinability or damage the tiny root.

No additional nutrition for Seedlings

Germination is not the end of the matter. The seedling you end up with is very vulnerable for the first 2 weeks. It’s vital in this phase that you don’t give it any extra nutrition. That could be fatal during this vulnerable phase. So just let nature do its work and wait patiently!

What to do if your cannabis seeds do not germinate: 3 practical tips

Cannabis seeds are real living organisms and as such are susceptible to many environmental factors, such as light, humidity and temperature. If you’re wondering what to do if the seeds don’t germinate, maybe you need to freshen up on what European law says about it.

The sale and possession of seeds are legal in our country, as they do not contain any trace of THC. However, if the weed seeds germinate, they would give birth to a plant capable of producing inflorescences with a high rate of tetrahydrocannabinol, turning your culture into an administrative offence.

The marijuana seeds that you can buy online in shops like Sensory Seeds are purely collector’s items and can be used for purposes that do not involve germination, such as collecting. However, in other countries, the cultivation of hemp seeds is legal for personal use, such as in some cities in Spain.

Here are 3 practical tips to protect the health of the seeds to be germinated (where cannabis home cultivation is allowed).

1) Which seeds do not germinate? Here is how you can recognise them before it is too late

There are many reasons why marijuana seeds do not germinate, and it is not always easy to recognise the cause. However, there are signs that you may be able to identify those specimens that are likely to cause problems. Improper storage is one of them and can be the cause of your seeds not germinating because they are already dead.

It can happen if you have bought your cannabis seeds from unreliable sites that sell off old items as discounted products. Seeds that do not germinate may have changed colour and become significantly darker or have a white patina on the rounded end; moreover, if you open the seed, you will notice that the embryo has become soft.

For this reason, we recommend that you always check the health of the seeds as soon as they come into your hands, mainly if you are used to buying your weed seeds online. In this case, you should only turn to reliable shops like Sensory Seeds, which guarantee the health of the products in your shop window.

2) Do you want to try to germinate an old seed? Here’s what you can do

If you have an old marijuana seed in your hands or you have tried to plant it, and nothing at all has happened, you can try to make a desperate attempt to resolve the situation. There are 4 ways you could proceed, and they are as follows:

  • Soak the seeds with enhanced water
  • Seed shell rubbing (scarification)
  • Cut the joint that closes the seed
  • Dissect the seed

The first attempt to do among these is undoubtedly to soak the unsprouted cannabis seeds in a container with sparkling water or, better still, enriched with fulvic acid or growing booster. Keep the solution at a temperature of 20°-22° and away from light for 12 hours: in this way you may be able to get moisture into the dehydrated shell and give the embryo the starting input, but be careful not to exceed 24 hours of soaking.

If after this attempt the seed does not show signs of life, you can move on to scarifying the shell, i.e. its abrasion to create grooves that facilitate the passage of moisture to the embryo. Insert sandpaper into a container, tape it up and put the cannabis seeds in it: after closing the lid, shake the container for a minute or two and then try again to soak the seeds in water for a few hours.

Still nothing? Take a knife with a smooth, sharp blade and slide it along the kerb of the two halves of the seed shell until it is removed: a very thick shell can make it difficult to open the seed to get the rootlet out. If the first 3 attempts are unsuccessful, dry the seed, cut the shell with a sterile scalpel along the groove under the shell and try to germinate it.

If you haven’t managed to win the battle in this way either, you will, unfortunately, have to feed the seeds to your budgies…

3) All you have to do not cause the cannabis seeds to fail to germinate yourself

There are many causes for a hemp seed not to germinate, including fungal infection. This type of mould can attack your seeds in the following cases:

  • Poor quality soil
  • Excess humidity
  • Too much watering
  • PH inappropriate
  • Poor ventilation
  • Temperatures too low

The guidelines for storing seeds before planting are stringent:

  • The temperature of 6°- 8° C
  • Humidity between 20% and 30%
  • Keeping in the dark
  • Avoid oxygenation
  • Maintain the stability of the previous parameters

If you clumsily follow these directions, you might run into the problem we’ve been talking about. Besides, if the extreme methods of achieving germination have not been successful, you may find that the embryo is infected with liquid-looking, yellowish fungi.

Other problems can arise from using chlorine-laden tap water (it is best to let it evaporate 24 hours before use) or from breaking the semen shell due to pressure, which you should always be very careful of.

Final considerations on unsprouted marijuana seeds

Poor germination is not always your fault, as there may be external factors that make it difficult or sometimes impossible. In some cases, the soil used may have been a fungus carrier or its type was not the right one; other times the fault is due to a malfunctioning or poorly calibrated conductivity meter.

Falling into a failure to germinate is sometimes almost inevitable: in some unlikely circumstances, you may have done nothing wrong, but your seeds will still not germinate.

To make a summary, cannabis seeds that do not germinate may be defective due to external causes or inadequate storage. If the seeds do not germinate immediately, you can try using the techniques we have mentioned in this article and hope that they work.

5 common mistakes when germinating cannabis seeds

Although the germination of cannabis seeds is a relatively quick and easy process, it is crucial to take into account a series of important factors in order to obtain as high a germination rate as possible. In addition, it’s in our interest that the seeds germinate as quickly as possible, and especially if we want to avoid problems like fungal infection or a low germination rate.

In our article on how to germinate cannabis seeds we explain step by step what you must do to achieve successful germination. Today we will take a look at the main mistakes made during this process, some simple errors that, as we will see, can easily be solved. Let’s see where many growers fail to germinate their seeds, it’s a great way to learn what not to do if we want to make the most of our seeds.

A germinating cannabis seed

Letting the germination medium dry out

By placing the seed in a moist culture medium, it begins a series of reactions that will lead to germination in a few hours or days. Whichever substrate we choose for germination, we must ensure that it never completely dries out, because as the seed stops absorbing moisture, it’s likely that the seed will cease its activity and never germinate. Cialis for Erectile Dysfunction http://valleyofthesunpharmacy.com/cialis/

For this reason, it is advisable to check every day to make sure the germination medium remains moist, especially if a heat source is used to achieve a higher temperature and therefore a better germination rate; the heat will cause the substrate to dry more quickly, something that must be kept in mind to avoid nasty surprises. In case of hydroponic cultivation it is always better to germinate in rock wool cubes, which of course must always remain moist.

The paper towel should never dry out once germination begins

Leaving seeds to germinate for too long

Another common mistake, in this case when germinating in kitchen paper or similar, is to let the seed germinate until the cotyledons appear. If we do this, then the subsequent transplant is very difficult, and it is very likely that we’ll damage the root in the attempt. Additionally, the longer the root is exposed to air and light, the more damage will result, so it is preferable to transplant it before this occurs.

To avoid problems, it is best to plant the seeds when the tap-root measures approximately 1cm, or 2cm at the most. This will make it much easier to transplant and we won’t harm the development of the roots, which can be expand into the new growing medium without setbacks.

Direct germination in soil

This is a common mistake that usually results in non-germination, especially if the substrate hasn’t been previously watered before sowing the seed but is watered afterwards. By planting the seed directly in the substrate, we run the risk of it being buried too deep, made worse when we irrigate the growing medium post-sowing.

To obtain much better results, first germinate seeds in kitchen paper, jiffy pellets or peat plugs used for rooting cuttings and then transplant them to the soil or to a pot once the small seedlings have been born. Another benefit of this method is that we can germinate a large number of seeds in a very small space, such as a small greenhouse, which will make it much easier to provide the correct temperature and humidity.

Temperature and humidity for germination

Cannabis seeds germinate correctly with relatively high temperature and humidity values. It will be necessary, especially during some seasons of the year, to use some source of heat to get a temperature of about 26-28ºC. For this purpose there are many options on the market, such as thermal cables or heated greenhouses. The latter are particularly interesting because they also provide the perfect high humidity environment for seed germination.

The ideal is to maintain the germination medium at about 26-28ºC and at 70% relative humidity. Lower values ​​will result in a slower and less successful germination, while higher values ​​can bring fungal or rot problems.

A heated greenhouse is perfect for germinating seeds

Planting the seed incorrectly

If you look closely at a cannabis seed, you will notice that it has a slightly oval shape, ending in a point at one end and forming a small “crater” at the other end, which is called the crown. When planting your seed (whether it’s a seed that you want to germinate, for example, in a jiffy, or a seed already germinated on kitchen paper that you want to transplant) you must keep in mind that this crown should always be facing upwards.

So, you should plant the seed with the tip down and the crown uppermost and facing you. Once the seed germinates the crown will serve as a hinge, so that the seed will open at the tip and let out the root. In case of placing the seed incorrectly, the tap root will grow upward and the seedling downwards, which should be avoided at all costs because it is likely that the seedling will not be born.

Planting at the incorrect depth

Too often the seed is buried too deep (a problem that we have already seen in case of watering after planting the seed), so the seedling may never emerge. In the other case, if we sow too close to the surface, we can find that the seed germinates well but the stem grows weak, bending and not allowing the seedling to develop correctly.

To avoid these problems it is be best to sow the seed at about 2cm depth. In addition, we can cover the lower stem as the seedling grows, so that it gains stability and produces new roots along the length of stem we have buried. In this way we can accelerate the growth of the plants.

We should plant the seed with the root downwards

Planting several seeds in the same pot

Although it may be tempting, germinating several seeds in the same container is not usually successful. In addition to the difficulty of correctly planting several seeds in the same pot, once they are born they will compete for the little space available for their roots. Having restricted root growth does not suit cannabis plants, which will grow more weakly and with greater internodal distance.

In addition, the scarce space between the plants will also mean they will compete for available light, something not recommended if we want to get the most out of each plant. The plants will produce very little lateral branching, and will center their growth on a weak main stem, with too long an internodal distance, factors that usually affects negatively on the final yield of buds.

We hope that this article will help you avoid problems when germinating your seeds, it can be very frustrating to start a grow with all the enthusiasm and excitement, only to run into problems straight away!

I’ve been growing since I was 13. I am 66. Not a boast. It just is. My comment is not so much about growing weed but rather about a lack of civility AND (not necessarily limited to only this forum). For the most part cannibis “enthusiasts” are wonderful people. Still, is it my imagination or are there a lot of condescending pricks (can I say that?) on these forums. Some of which are “Newbee Experts” criticizing anything that didn’t come out of their own mouths? When the Real Expert offers an opinion that doesn’t mesh with the self proclaimed genius’s vast knowledge base, they tend to respond with very little grace. So I guess this is more about the general state of things and what some people believe is acceptable behavior. Just a thought. Cannabis community, let’s treat each other with respect. We’ve made so much ground and it’s taken SO MANY years. Let’s not screw that up.

Giacomo 2022-07-01
Just a quick poll for those of you with a few growing seasons under their belt. Have you found that your failure rate with seed germination has been increasing. I suppose it is possible that I’ve just had a bad run but my success over the last two grows has been about 50%. I’ve been doing this stuff for a long time and my technique is sound. Just seems like I have more duds lately (I have not purchased seeds from Philosofer).

I quit reading long back when the initial 100 seed results were reasoned. I’ll likely be missing many points observed. Simple opinion, for better than 25 million years of natural survival this plant has recreated itself for man to adapt to its uses in a very short 10,000 or how ever many years there’s been somebody crapping In a watermelon patch Surely it knows its way around a 2cm [email protected]&?ing hole surrounded by its predecessors environment. I would think genetically it knows what the !(@& to do. Especially if you are using a “Feminized seed”. Now, surely many observations have been made justifiable or not the laws of average are easily debatable, but I believe that the laws of average have established the standards many moons ago friends. Maybe I’ll fill up a kiddie pool 4ft Dia. @6 inches deep perlite and drop a 100 seeds through a pine bow from 6 feet high and then document the seeds position when it’s at rest in the perlite.. . I’m Extremely new to cuktuvating cannabis, my 2nd year. My first year turned out peesonally satisfiable at best simply because I planted shark cookies. I germinated in a paper towel, from there I rested the seed however it rested in a tub of perlite with an aquarium bubbler, also a circulator moving a solution of compost tea through the roots for 2 weeks, then put them in a small crawl area with a fan and a few lights for another 45 days, and then moved them to a bucket and put outside for the next 3 months and then brought back inside for another 2 weeks. So any opinions that we all have are open for discussion, but the only resolution for judgement is our own environmental abilities to nurture the development of variable genetics. Happy gardening friends..

Hi and thanks for your comment. We’re happy that your first year of cultivation was a reasonable success, we hope that this year will be even more so! Germinating seeds may seem like the most natural and easy thing in the world, and that’s how it should be, but it’s amazing just how many people fall at this first hurdle, and when the seeds are not particularly cheap, as in the case of cannabis, it becomes even more nerve-wracking, especially for beginner growers and those who have no basic experience of growing other plants like vegetables, flowers, etc. There’s no real substitute for experience in this game, and the more seeds we pop, the more confidence we get. Thanks again for your comment, best wishes to you!

Hello Good day I have some that looks like stale might be more than years old seeds. It was a given to me by a friend and I doubt it was preserved properly in proper containers. Will it still germinate?

Tim 2021-11-24
Hi, thanks for your comment and question. The older the seeds are, the less chance they will germinate, and if they weren’t stored in good conditions (dry, cool, stable, e.g. in the fridge) then the chances of non-germination become even greater. You can try a few things to help improve germination rates, for example, the application of fulvic acid and/or gibberellic acid will give older seeds a better chance of germinating. Try germinating a few of the seeds in the normal way and then if you don’t get success I’d look at using one or both of the compounds I mentioned. I hope that helps, all the best!

I have germinated five seeds of different stains, all paper towel method. All sprouted.. All healthy.. All put in good seedling raising mix but the problem is they just sit dormant just not growing. I grow under lights. Last year.. No problems this year no growth. Seeds r less than a year old. HELP.

Tim 2021-09-08
Hi and thanks for your comment. To work out the problem, we need to eliminate a few possibilities. First, check that the temperature and humidity levels within your grow area are suitable for vegetative growth: ideally from 20 to 28ºC with 40-60% RH. Then verify whether your lamps need changing – old bulbs put out significantly less light than new ones, which could be leading to poor growth. If all those factors are as they should be then the most likely culprit is the soil mix itself – the quality can vary from season to season, even with the best brands, so it’s always possible that there could be pests or pathogens in the soil which are preventing the seedlings from making progress. I would recommend trying with a different brand of soil to see if that makes a difference. I hope that helps. Best wishes and good luck!

Fishnass 2021-08-30
I germinated in paper towel until tap root was as long as seed it curled around the seed anyway my question is if I planted in jiffy pod should I put it under light or wait till it pops up to put it in the light .

Tim 2021-09-01
Hi and thanks for your comment & question. The newly germinated seed doesn’t really need a light source while it’s below the soil surface but as soon as it pops out it will need light to prevent it from becoming stretchy, lanky and unhealthy. For this reason, it’s probably best to keep it under a light with a photoperiod of 18 hours light and 6 hours darkness for the day or two that it takes to break the surface. I hope that helps, best wishes!

Master 2021-08-13
You’re incorrect, seeds should be planted pointy end up crown down.

Tim 2021-08-16
Hi Master, thanks for your comment. I honestly don’t believe there’s a correct or incorrect way. In our time, we’ve tried germinating seeds point down, point up and also laying them on their side in the soil, and we’ve come to the conclusion that it makes no difference at all – we certainly didn’t see any real difference in the results of one method compared to another. In nature, cannabis seed dispersal doesn’t rely on the seed landing in the soil in any particular position and it’s managed to spread pretty well! That said, if you like to sow your seeds pointy end down, then that’s great, keep doing it your way if it works for you! Best wishes!

Sean 2021-05-17
I had my seeds in the paper towel for 3 days. The tap-roots appeared(not out just showing a bit) and I planted them in the soil. 3 days have past and I haven’t seen any progress. Is there a reason why this is happening?

Tim 2021-05-17
Hi Sean, thanks for your comment. As long as the soil is neither too wet nor too dry, there shouldn’t be a problem with the seeds. They can take a few days to pop their heads up above the surface once they’re planted, the root needs to work its way downwards and find a solid hold to be able to push the seed head out of the soil. Speaking from personal experience, don’t be tempted to dig around looking for them as you’ll probably do more damage than good. The only times that seeds didn’t come up for me were the times I overwatered them, it’s crucial that they get enough air at this moment and too much water can lead to them rotting quickly. Of course, if they totally dry out then they’re not going to survive either. At this stage, I’d just recommend patience, good luck! Best wishes!

This article has a lot of nonsense in it. From Mandala Seeds: A #1 seed killer is a closed humidity dome/mini-greenhouse. Humidity domes are only required for rooting cuttings. Many growers make the mistake of thinking that they need a high ambient humidity for germination or seedlings. This is an unfortunate myth of cannabis cultivation. The high humidity and lack of fresh ventilation quickly causes fungus in the soil or growing medium and the seeds can rot! Cannabis is not an orchid or swamp plant! The seeds need a well aerated growing medium to germinate well. Seedlings also cannot tolerate high humidity and can easily be attacked by fungus such as fusarium and pythium. Only the soil or growing medium should be moist for optimal germination and seedling growth. Ambient humidity is best at or below 50%. Btw, seed should be planted with the pointed end UP, not down. Tap root ALWAYS goes up no matter how you place the seed. It’s by the nature, goes against the gravity to create a support for itself so it can push the seed out. It you put it with the pointed end down it will have to make double turn loosing the precious energy stored in the seed.

Tim 2021-05-13
Hi, thanks for your contribution. Mandala Seeds give some helpful advice but they don’t have a monopoly on germination methods! In my 20 years germinating seeds I’ve tried all different methods and I’ve found good and bad in all of them. except for the methods using moist paper towels, I refuse to use it these days – I found that’s a great way to get mold problems and a really bad start to the plant’s life! That definitely is far too much humidity. as for ambient humidity, we don’t specify anything in this post. What we do say is that the medium in which the seeds are germinating should be at about 70% humidity for the best results. There’s nothing wrong with using a humidity dome or mini greenhouse, as long as you know when to start ventilating. of course if it’s kept sealed all the time then problems are bound to arise! These days I start all mine in a glass of water with a few drops of H202 and then once the seeds open (usually 24 hours) they get transferred to the substrate. As for the point down/point up debate, I think I’ll need to do a side-by-side comparison to settle this in my own mind. I’ve always planted them point downwards or on their side and I’ve yet to see any weird stuff like roots popping out of the surface, or doing a loop-the-loop before the seedling breaks the surface. But it’s clear that the debate needs to be settled so I’ll do an experiment and I’ll be happy to be proved wrong! EDIT: I’ve since germinated over 100 seeds as a test, 1/3 of them went in the soil with the point downwards, 1/3 sideways, and 1/3 with the point upwards. Most of the seedlings broke the surface at around the same time but it’s clear to see that the ones that I’m still waiting for are mostly those that went in with the point upwards. The next step has to be a test in a terrarium so I can actually see what’s going on but I’m almost ready to call complete BS on this “point upwards” theory, FWIW. Thanks again for your comment, all the best!
