Obtaining certified seeds from a seed bank is something we would always recommend, and if you turn to the black market to buy and sell seeds, it is without any guarantees. Local guidelines may vary from region to region, and care should always be taken.
Did you know that cannabis seeds are extremely nutritious, just like hemp, which has long been sold in health food stores? In fact, they are packed full of protein, fiber, healthy unsaturated seeds rich in omega oils and many vitamins. Plus, they contain an impressive range of minerals, such as iron, sodium, potassium, and magnesium.
When you have plenty of extra seeds for no additional cost, you have the perfect opportunity to experiment with growing conditions. Why not try a stealth guerilla grow in the wild by planting some seeds in the middle of the woods? Or you could try a low-cost hydroponics setup. You have nothing to lose with these seeds, so why not use them to learn a new cultivation technique? After all, if it all goes well, you will have grown some extra plants – ready to harvest!
3. Give them to your pets
Another option – perhaps less risky – is to give your excess seeds to friends, without involving any financial transactions. If you are completely transparent about where the seeds come from, this can be an excellent way to encourage someone to get into growing cannabis, and you could have a new weed growing buddy to swap clones or buds in the future.
If you find seeds in your crop, your plants experience some degree of stress during the vegetative or growth phase and/or the flowering period. In that case you might have hermaphroditism issues. This can then lead to accidental pollination of the female flowers, which causes them to produce seeds rather than buds.
Hermaphroditism occurs because a single cannabis plant can produce both male and female flowers. Unless you choose female seeds (which guarantee good success for growing only female plants), you could have several hermaphrodite plants if they are exposed to light stress, water stress, environmental stress or nutritional stress.
First, discard any immature seeds. Mature seeds have a different appearance compared to those who are immature.
Some varieties of cannabis can produce male parts alongside female flowers on the same plant, especially if exposed to environmental stressors. These plants are known as hermaphrodites, and sometimes they can self-pollinate to create seeds.
Most cannabis plants begin flowering when the amount of light they receive on a daily basis reduces. Outdoors, this happens when the sun starts setting earlier in the day as the season turns from summer to autumn. Indoor growers can control when a plant flowers by reducing the daily amount of light plants receive from 18 hours to 12 hours.
How weed clones work
Remember, once a seed germinates, the real work begins. Sexing, selecting, vegetative growth, flowering, and the eventual harvest all lie ahead.
Marijuana seeds can be acquired from an array of sources and can vary in quality. For more info on how to buy marijuana seeds, check out our Guide to buying cannabis seeds.
As we’ve mentioned, cannabis is a dioecious plant, meaning male and female reproductive organs appear on different plants.
We hear this question all the time from clients and beginner growers, and the answer is a resounding no. There is simply no way to tell the sex of a cannabis seed just by looking at it.
Are your seeds light or dark in colour? Are they tough or do they turn to dust when you press them between your fingers? These are just some of the ways to tell if a seed is healthy and worth growing. Keep reading to learn more.
Growing Seeds From A Bag (Bagseed)
We do not recommend taking the size or shape of a seed into consideration as a sign of its quality. Some strains simply produce smaller seeds than others, and sometimes the same plant can produce seeds of different sizes and shapes. Never discard a seed just because it is smaller or of a different shape than another one.
However, slight patience is required when conducting the float test, as results are not immediately apparent. You’ll have to wait for approximately 1–2 hours before confirming the results. Some good-quality seeds will need adequate time to absorb enough water for them to sink. Use this time to go water the garden and get some much needed pruning done. Upon your return, any seeds that remain on the surface are most likely not viable and won’t be worth further time and effort.
This simple and cost-effective method is a great way to tell the good genetics from the bad; they will sink or swim, literally. Seeds that remain buoyant on the surface are more than likely of poor quality and are to be discarded. Seeds that sink to the bottom like a botanical cannonball are probably healthy and should be germinated.
