cannabis seeds germination problems

The following plant was grown in an unsuitable growing medium with no drainage and started showing signs of overwatering. Always start with a quality potting mix that has good drainage, and never allow the top of your growing medium to look this wet!

Here's another example of a seedling damping off due to too much water (drowning roots), whis time combined with not enough light. After a few days of these conditions, this seedling just fell over and started dying.

FAQs – Frequently Asked Questions

The young cannabis plant roots will quickly use up all the available oxygen that's been dissolved in the water, and then the roots will sit in water until the water slowly evaporates on its own. Some containers such as smart pots and air pots allow air in from the sides, which can help dry the growing medium faster, but it’s better to use proper technique from the beginning.

Sometimes the leaves sort of fold downwards due to heat, too, like this seedling

In addition to the germination rates we also control other important factors of quality such as a high level of healthy seedlings. Seedlings should not appear crippled, feeble, tiny, with dehydrated leaf tips, etc. However, this is a biological product and despite the best production methods a minor % of seedlings (calculations based on 100+ seeds) may not appear healthy and need to be removed. It is therefore always best to germinate an extra seed or two as a back-up, especially if you are only growing a few plants.

Some or all seedlings fell over and died

This does not mean that pre-soaking should never be used with seeds from other sources, or that we criticize growers who prefer this method. We are aware that some breeders recommend it for their products. But to prevent complications and achieve the consistent level of high germination rates that you should be getting from your Mandala seeds please trust our advice and follow our guidelines.

In some rare cases frost during delivery can damage seeds. If your seeds are subjected to freezing temperatures (such as lying outside in a mail box) you should dethaw them slowly. Put them in the refrigerator a couple of hours for this purpose.

Please take note that customers who soak their Mandala seeds in water or wet paper tissue do so at their own risk. We are not accountable for any failure in germination or complications caused by this method.
