Overwatering is much worse than occasional underwatering, as plants can almost always recover from slightly dry conditions. But when they’re constantly overwatered, this deprives the roots of oxygen and will lead to all kinds of troubles like fungus and root rot. Always allow the soil to dry out between waterings. Less frequent watering is better than overdoing it!
Good soil for cannabis has a light, airy structure, preferably with some perlite mixed in. This ensures adequate drainage and allows roots to grow unhindered. Cannabis won’t do well in soil that is too dense.

8. NOT HAVING PROPER VENTILATION
If the pot is too small, the growth of your roots, and therefore the growth of your entire plant, will be restricted. If the pot is too big, this increases the likelihood of overwatering, fungus, and root rot.
As an alternative to plastic pots, you can also use fabric pots (smart pots) or air pots. If you want to learn more about the different pots used to grow cannabis, check our article on the subject.
The RQS Starter Kit comes with everything you need to give your cannabis seeds the best and safest start in life. It comes with a propagator and lighting, Easy Start seedling pots, perlite, and beneficial bacteria to encourage germination and growth. It even includes three popular cannabis seeds, so you can start right away! When your seedlings have reached 2–3cm, you can cut up the pots and easily transplant your seedlings into their growing medium.
Excessive moisture is also bad news for seedlings. When humidity levels are too high or when you overwater your seedlings, this can lead to the dreaded damping off, a deadly fungal disease. Seedlings will become weak and tip over, and there is nothing you can do to save them. Avoid extremely high humidity and overwatering, and make sure to use a sterile medium for germination.
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.
Unlike other agricultural crops (like vegetables, fruit, or grain), cannabis hasn’t undergone the vigorous breeding techniques that ensure a stable crop. This means that you’ll sometimes sow a pack of seeds technically labeled as the same “strain,” but may end up with very different looking plants. It also means that the individual seeds you buy from a seed bank can vary in appearance.
Appearance And Feel – Checking The Color, Size, and Shape Of Your Seeds
A solid way to obtain great seeds is to find a reputable seed bank. These companies pride themselves of their breeding skills and make sure that their customers receive exactly what has been advertised. They have reputations to cater to, so delivering anything less would only harm their image.
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.
The alternative to this is to risk buying seeds from a hobbyist. This isn’t to say that hobby growers cannot produce fantastic genetics, but if you don’t know them or their skills, there’s no way to know whether your seeds will grow.
