Never let your young sprouted marijuana seeds dry up
The main signal that tells marijuana seeds that it’s time to start sprouting is the presence of moisture and heat. The combination of warm and wet (springtime conditions) “prompts” the seed to start burrowing their main root (taproot) through its shell.
If a seed’s root breaks through the shell and the water around has dried up, your seedling will die. No doubt about it.
Seedlings are very fragile at first. Once they’ve sprouted, the roots need to stay constantly moist to stay vibrant and healthy. It is important to make sure the seeds have access to water the entire time during germination, no matter which cannabis germination procedure you use.
Keep Them Warm
Seeds germinate best in warmer temperatures and young marijuana seedlings do best with a higher relative humidity in the air. When seedlings are very young, they grow faster and healthier when they can absorb moisture from the air through their leaves while their roots are still developing. Dry air won’t normally hurt your seedlings, but it doesn’t help them at all. Again, think springtime conditions.
You can use an incandescent bulb (or two) placed over the marijuana seed germination area to help keep things warm. Incandescent bulbs are the opposite of what a grower typically wants: they cannot be used as grow lights, but they are great at generating heat. Some people will also place a heating pad (the kind you get from a garden store for seedlings) underneath seeds to help aid in the germination process.
Essentially, you want to make sure your seeds or sprouts are kept warm and moist at all times, that their roots are not exposed to direct light, and that they get planted right away following germanation.
There are a few different ways to germinate your cannabis seeds, and in our next article we will cover some easy methods that have proven to be successful.
