Once you see the taproot, it’s time to transfer your germinated seed into its growing medium, such as soil.
Keep a close eye on the temperature and moisture level of the soil to keep the seed happy. It’s very delicate at this stage. Use a spray bottle to water it—over-watering can suffocate and kill the delicate sprout.
It’s important to keep the delicate seed sterile, so don’t touch the seed or taproot as it begins to split.
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.
Autoflowers can be started in early spring and will flower during the longest days of summer, taking advantage of high quality light to get bigger yields. Or, if you get a late start in the growing season, you can start autoflowers in May or June and harvest in the fall.
Additionally, every long-time grower will tell you that clones degrade over time.
Because only female cannabis plants produce buds and you want them to focus all their energy on producing buds and not seeds, it’s important to identify and get rid of male weed plants so they don’t pollinate females. If females are pollinated, it will give you buds filled with seeds, making your weed harsh and unpleasant.
Seeds are the result of pollination. That means the seedy cannabis buds (which come from a female plant) may have come into contact with pollen from a male plant. Therefore, it’s possible the grower didn’t identify and remove all the male plants before the released pollen. It’s also possible that the plant self-pollinated (sometimes called herming) which is often the result of plant stress during the budding phase but can also be caused by genetics.
What does it mean to find seeds in your marijuana buds? Is it something to be worried about?
Does it mean the weed is bad?
There’s a seed in my bud!
I’ve seen some growers get impressive results with bagseed, but overall results seem to be hit or miss. Plants can grow in odd ways and often either the yields or quality isn’t as expected. The problem is that seeds often don’t “breed true” to the buds that they came from. That is why many growers either stick to clones (which are exactly the same as the “mother” plant) or purchase seeds of a stabilized strain from a trustworthy breeder, where each of the plants will grow the way you expect, and buds more consistently have the smell, yield and potency they’re supposed to.
If it’s very seedy the buds may not feel as potent, though a few seeds here and there won’t make much difference in potency. The main problem with seedy weed is that you are getting less smokeable bud for the amount of total mass there. If it is seedless, you will get a lot more bang for your buck. Seedless bud (sinsemilla) is considered to be the highest quality and most potent type of weed.
Finding a hermaphrodite in your growroom can happen at any stage of the flowering cycle and is indicated by the presence of male flowers growing on the same plant as female flowers. As with all species in nature this can occur in varying degrees. A plant can become slightly or majorly hermaphroditic. In cases where singular male flowers are found between the branch and stalk nodes, you should be diligently removing them as they grow. You must re-inspect the plant top to bottom every few days to be sure pollination and seeding doesn’t occur. If you find male flowers (anthers) actually growing from within the female flowers (buds) the situation is a little more dire. You can still remove all the male anatomy as it appears, but it will be harder to find and much more prevalent. This is a horrible discovery that leads to a tough decision: Should you let the plant live and risk the whole crop being ruined by seeds?
Negative stressors can combine with small interruptions of the light cycle to cause hermaphroditism, especially with less-stable, clone-only hybridized strains. When the night cycle is abnormally interrupted, it sends a mixed hormonal signal to the plant. This can cause a full female plant to throw some male flowers. Male flowers are easy to identify, especially when side by side with female flowers. Male flowers look like small bunches of bananas, which will take a week or two to swell before they burst and release their pollen.
Cannabis plants are monecious. This means they have the ability to be either male or female. Or in the case of hermaphroditism, they can be both. The reason to make sure there are no males or hermaphrodites in your garden is because male flowers make pollen. When pollen touches the white hairs on a flower, it makes a seed, and seeded weed gives you headaches. Even though there are reasons in nature hermaphroditism could be important, such as continuing the species in case there is no male present, hermaphroditism is generally a bad thing when talking about cannabis plants.
I have an indoor growroom and in my recent harvest I found seeds in the buds, but I’m sure there are no male plants in the room. I’ve heard that light leakage can cause plants to become hermaphrodites. Is this true, and if so, do you have any tips for avoiding this?
Light poisoning refers to the flowering night cycle of a plant being unnaturally interrupted with light. The best way to prevent this is to close yourself inside your darkened room during the daylight, and then after allowing a few minutes for your eyes to adjust to the dark, check for any light leaks from covered windows, door jams, etc. Also cover all timer and appliance lights with tape.
Light poisoning is the most common cause for a normal plant to hermaphrodite.
In either case, once hermaphroditism has compromised the safety and purity of your sensimilla, the plant should not be propagated further. Remember, once a hermy, always a hermy. The plant pictured here is in the tenth and what should have been the final week of ripening, but a timer failed and one light stayed on continuously for almost two weeks, causing this vegetative regrowth. Because the light was continuous, the plant made no pollen. This method of re-vegging can be used to save a flowering plant you have no copies of, but be careful, as this may cause some strains to hermaphrodite.
