cannabis seed wont come off seedling

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.

In this guide I will explain how to remove the seeds outer shell from the seedling without causing any damage to the plant.

How to remove the seed shell from a Cannabis seedling

If the shell is still too difficult to remove after applying some water, repeat the process again.

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.

Why does the shell get stuck to the 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.

Death during the germination of cannabis seeds is one of the most frequent failures suffered by every grower over the course of his or her cultivation career. There are several possible reasons that can lead to the seeds dying before they even open and begin to grow, which we’ll examine here.

If the plan is to grow automatic varieties, then during the first two weeks we water with 100 to 350ml per irrigation, every 1 or 2 days. Remember that the substrate must maintain a minimum of humidity to allow the plant to feed and continue to develop normally. If it is raining and the plants are outdoors, it’s a good idea to move or cover them, to prevent the substrate from getting soaked, which could easily lead to root zone problems.

What to do with leftover seeds or unopened seed packs

If outdoor temperatures are around 20 to 24ºC, then we shouldn’t need do much more than start the seeds to germinate and wait for them to open, following the precautions already discussed. But in case of having warmer or cooler temperatures, we must act to raise or lower the environmental temperature for optimal germination, and find the best location for germination to be successful.

The start of the growth period is a very important stage in a plant’s life, so several aspects must be taken into account so that it does not die of any of a number of causes.

The same can happen in other germination media such as jiffy plugs, where the most common mistake is usually not draining away the excess water after re-hydrating the compressed peat. To this error, we can add that of burying the seed at more than twice its own depth, in which case it may not emerge despite having germinated perfectly well, but instead, simply end up rotting due to excess water and lack of oxygen. This error is also frequent in growers who germinate directly in the soil because when they first irrigate, the seed can be washed down into the soil resulting in them being buried too deeply, which makes it difficult for the seedling to reach the surface. It is always better to wet the substrate first, before sowing any seeds.
