Do your due diligence and verify when local temperatures are high enough to set your plants outside. Usually, waiting a couple weeks for higher spring temperatures is worth it!
Excessively high temperatures in your germination environment can lead to slow and stunted growth, and it can cause your soil to dry out. The optimal temperature for seed germination is a moderate 20–25°C.
To prevent spoiling your seeds, avoid unnecessary handling. Use clean gloves and some disinfected tweezers or something similar. This will greatly minimise the risk of your seeds being contaminated.
13. TOO MUCH LIGHT
If you allow your seeds to germinate for too long, transplanting them safely will become difficult. The reason for this is that the longer the roots are exposed to air and light, the more likely they are to become damaged. Moreover, the longer the taproot, the higher the risk for accidental damage when transplanting.
Why are my seeds not germinating? With our germination troubleshooting guide, you can get to the bottom of why your weed seeds aren’t popping. Avoid these germination mistakes and get your grow off to a great start!
Solution: Only plant your seeds in a sterilised (i.e. new) potting mix as this won’t contain these harmful organisms. But your substrate isn’t the only thing you need to keep an eye on. You’ll also need to make sure your containers are clean, as these can also carry mould and other harmful pathogens. If you encounter fungus problems when you’re germinating, it is best to get rid of the seed and the contaminated growing medium and start over.
Believe it or not, hemp seeds are a major component of many types of birdseed! That’s right; birds love them just as much as you do. But birds aren’t the only critters that would love nothing more than to chow down on your seeds.
the cotyledons were yellow but as soon as the light started to get at them they started producing energy and straightening up and unfolding and got green
tho just about 3 weeks agao had an em tri tinity kush do this so i helped it its about a week behind the others
I usually mist the seedling a few times and then gently try to remove it with tweezers.
I use 2 toothpicks.
take it off slowly and carefully or it will die. I ad some slow germers and the thing was glued on and the plant was trying to grow inside. It would have died.
just had 2 die from not burying deep enough. the shell got hard and leaves never shot out
first set of leaves start coming in then they really start producing their own energy
Why does the shell get stuck to the seedling?
In this guide I will explain how to remove the seeds outer shell from the seedling without causing any damage to the plant.
When you plant a newly germinated seed into soil the hypocotyl (basically the stem) grows through soil and reaches for the light. As it pushes up through the soil the outer shell should detach, but sometimes it doesn’t and it gets stuck.
If the shell is still too difficult to remove after applying some water, repeat the process again.
How to remove the seed shell from a Cannabis seedling
Every Cannabis grower has had to deal with a seed’s shell getting stuck to the newly sprouted plant. It’s not a major issue, but if left too long it can cause damage to your young seedling.
The most common reason for the shell getting stuck is not potting your seeds deep enough. If the hypocotyl doesn’t have to push through much soil then there’s less movement and friction to detach the shell.
