old marijuana seeds won’t germinate

Seeds that won't germinate

If you have chlorine in your water, then that will kill your seeds end of story. If there was chlorine in the water you used with paper towels, that’s the end of the story.

Chlorine kills your seeds and plants.

If you have chlorinated water let it sit out for 24 hours so the chlorine is no longer in the water. Then use it.

Okay to all you paper towel heads and water nuts. I have been saying this for a long time now but found a site which states it nicely. Read this and don’t lose any more of your precious seeds needlessly.

For an optimal germination result the seeds should be planted DIRECTLY into the substrate. We clearly advise against using pre-germination methods or soaking. Please do not place the seeds into a glass of water or in moist paper tissues. Fresh and healthy seeds prefer a nurturing and airy substrate to germinate in – just as mother nature has meant it to be. Cannabis is a plant species originating from semi-arid and temperate biotopes and the vast majority of modern cannabis hybrids contain a substantial percentage of these genetics. Cannabis seeds are not adapted to swampy wetlands, but they are suited for germinating in well drained soil/substrate. In nature they rot if they fall into a puddle of water. and there are no paper tissues lying around either. Taking into account these botanical facts, it is quite logical that by creating germination conditions that are similar to those of the natural habitat one can expect the best results.
What happens if one uses pre-germination methods?
1. Soaking seeds in water/wet paper towels is a method which can be used for old seeds (3+ years) that are drying up and losing germination power; and for pure land race equatorial strains such as from Africa. Both factors do not apply to our seeds. Fresh seeds have a healthy embryo whose cells are filled with water. But excess water causes the cells to bloat, depletes oxygen and leads to the tissue rotting away before the seed embryo can germinate. Old seeds have lost water in the cell tissue, the embryo starts to shrivel, which is why germination rates drop the older the seeds are. Therefore, old seeds (ie. 3+ years) can soak up more water before adverse conditions cause them to rot. This is one of the main reasons why various seed stock reacts differently to pre-germination methods. Especially novice growers make a lot of mistakes with pre-germination methods such as soaking seeds in water for up to 1-2 days. Even if one chooses to pre-germ seeds it has to be done correctly.
It is in a growers best interest to choose a germination method with the lowest risk of complications. Because we want customers to have the highest success rate possible we recommend the most convenient and safest method. This does not mean it is the only option. We simply believe it carries the lowest risk. In fact, planting seeds directly in the substrate is also the most plant friendly method for any type of seed stock. The reasons are explained below in paragraph 2 & 3.
2. Placing healthy & fresh seeds in water/wet tissue can lead to the development of fungi or bacteria on the seed hull. Lack of oxygen and contaminating substances in the water/wet tissue promote fungal growth which can be transported to the substrate later on. Often the seed simply rots away if left for too long in a glass of water, or wrapped up in wet tissue.
3. Once the seed sprouts in a glass of water or paper tissue it already has the taproot growing out of the cracked seed hull. While transplanting the germinated seed it is very difficult, indeed impossible, to prevent damage to the delicate taproot. Many sprouted seedlings handled in this way show retarded development, or even simply fail to appear out of the substrate after transplantation. Handling seedlings this way can impair the health & vigour of the plant for the duration of it’s life cycle – especially if other disturbing factors occur during the early stages of growth.Professional horticulturists rarely use pre-germination methods to actually grow out the seedlings because of the shock suffered from transplanting them. For example, we use the paper tissue method only as a quick test for germination rates of aged seed stock from our genetic repository. This allows us to see beforehand how many seeds we have to put in soil to get the amount of plants we require for breeding projects.
Germinating cannabis seeds is not difficult. All you need is some basic information on what is important and everything should work out fine.

What do you mean by chlorinated water ?

If you have chlorine in your water, then that will kill your seeds end of story. If there was chlorine in the water you used with paper towels, that’s the end of the story.

Chlorine kills your seeds and plants.

If you have chlorinated water let it sit out for 24 hours so the chlorine is no longer in the water. Then use it.

I figure the guerilla growers in jamaca or africa don’t use city water, therefore have no trouble with chlorine.

So you recommend adding chlorine to your water before using it ? Is that what you do to your bottled water ?

Letting the water sit out for 24 hours to disperse chlorine is not a myth, you can look it up it is scientific fact.

Here is the science of what it does to your plant:

Chlorine damages cells by releasing free oxygen which combines with cell
proteins causing them to denature. Because the hypochlorite ion forms when
such compounds as sodium hypochlorite (NaoCl; bleach)contact the organic
materials which make up the cell membrane, it is also likely that the
lipoprotein structure is disrupted, causing cytoplasm leakage and killing
the cell. I hope this helps.

I hope that keeps you from wondering about the it all being a myth.

Also here is some kids high school science experiment showing that chlorine kept I think 64% of his soy bean plants from germinating.

Chlorine is bad.

Testing out a bunch of methods to germinate 35 year old seeds.

Hi all. I'm new to cannabis cultivation but I've had botany and plant growing as a hobby for many decades, starting at age 10, so I'm quite familiar with plant cultivation. I also have a science background with access to the published research where I work. I've had one successful crop from new seeds under my belt from last year after Canada legalized pot cultivation and sales. This year I want to grow high cbd and thc varieties although I can't find cbd seeds for sale. But the main thing I want to try is germinating very old seeds.

I've got a bag of weed seeds about 34 to 40 years old or maybe even older. I've had no luck getting any to germinate successfully. Some have cracked open and when I scrape off the seed coat, sometimes I find a nice little yellowish green embryo inside complete with a root but they won't develop past that point. Eventually I'm going to try tissue culture techniques if necessary, but before I do that I'm going to try a number of other cheaper and easier methods. While there isn't a ton of information on germinating old cannabis seeds in the scientific literature, there is a lot of research into helping old seeds of other species to sprout. Some of the methods utilized with pot in the literature include using hydrogen peroxide, vitamin c, sucrose, and some other methods/compounds. I've also scoured the interwebs for literally months and found lots of suggestions including the sandpaper method, germinating liquid from dried food beans which I haven't tried yet but plan to soon. But none of them have proven to germinate such old seeds successfully. In the scientific literature, so far I've found about 15 different techniques and compounds used with maize and other seeds and I'm going to try them all in different combinations.

If any of you have successfully germinated very old seeds stored properly or improperly, let me know what worked so I can test it, or if you have heard of something that works and haven't tested it, let me know what it is and I'll add it to my list of things to try. I will update the sub with the positive or negative trials I've run. BTW, I'm very aware that old seeds often produce mutated or sub-optimal plants. I don't care about that, I just want to get a method that works. Thanks.
