But sometimes the stem is growing too tall, weak and thin and can’t support the weight of cotyledons anymore. Most seedlings are tall and skinny and look vulnerable, and generally it’s not a problem. Seedling Stretching: Reasons and Solutions In this case, the seedling will encounter more resistance on its way up and the shell will slide off. Keep the surface of the medium moist at all times, and you probably should think about placing the seed a little deeper than you did before. In your future grows, make sure that sprouts emerge from the medium already without a shell. Most seedlings can survive this without apparent shock or stress. If you did pull the sprout out of the ground, you can still stick it back in (probably, it’s best to remove the shell first). It’s better to make the shell wet again and wait a bit more. In this case, the procedure described above can result in your plucking the sprout out of the soil completely. Warning: Sometimes, the seedling hasn’t rooted too deeply and has still a very short tap root (like an inch or so). The one in the center still retains the membrane. We have removed shells from the seedlings on the right and in the center. Make it wet and when it gets soft, pluck it with your fingers. The membrane is too dry and acts as a straightjacket. Usually, it’s the reason why weed seedling is not opening. Sometimes the shell comes off, but a thin membrane covering the cotyledons remains. It will be enough to easily remove them from cotyledons. We’re wetting the shells with a drop of water. If the seedling is already too tall to be covered with wet soil, spray it with water or put a droplet of water on the shell: this will make it wet and mushy after a while. If not, the shell will be wet enough in a couple of hours, so that you can easily remove it with your fingers. If the seedling is still tiny and can be covered by moist medium, by all means do so. So you have to remove the shell yourself as soon as possible. Probably, most seedlings will find enough strength to eventually shed the shell, but meanwhile a lot of time will be lost and you’ll see a lot of stretching. Only one of them has cast off its shell on its own. This is day 1 for three OG Kush Auto seedlings. Too often, when a weed seedling is sprouting from the medium, the cotyledons are still stuck in the shell and it won’t come off on its own.
