Young seedlings love humidity, and a constant 60-70% is ideal at this stage. Use a cheap mister bottle, and spray regularly freshwater (ph- 6.5-7.5) over the leaves. This increases humidity, and washes dirt and dust off the leaf surface, unclogging stomata and enabling the plant to breathe properly. In natural conditions, the rain would do this for us.

Watering the seeds
Problems can occur during germination. Here is a list of some of the more common reasons why your seeds may not be doing so well.
With a thin pointed object such as a pencil, make a small hole in the center of each jiffy-pot about twice the depth that the seed is long (This varies with strain, but 5-8mm deep should be sufficient. Often the mistake is made of planting seeds too deeply, and they rot before they see the light of day. To ensure this doesn’t happen, never sow seeds deeper than 1cm). If sowing more than one variety remember to prepare identification labels in advance and label them as you go to prevent mix-ups.
Using the mister bottle, spray the freshly covered seeds until the mix is damp. Don’t pour water onto the pots as this can wash away the mix and expose seeds.
As soon as the seedlings have germinated they need light. The food store supplied by the seed itself has all but been used up, and the plant needs light to photosynthesize and grow.
It is very important to only put one marijuana seed per jiffy pellet.
Take one of your seeds and put it about .5″ deep in the pellet. It does not matter which way the seed is turned. Cover it with some of the top soil.
If you have a jiffy pellet kit with a dome, place that over the top. Marijuana seeds need a relatively humid environment to germinate, and the dome will help with that. Just make sure to take it off a few times per day so the seeds can get fresh air.
Anywhere from 2-8 days later, you will see your marijuana seeds begin to pop their heads out of the jiffy pellets. This will not happen to all your seeds at one time, so be patient and do not mess with the ones that need a little extra time.
My favorite way to germinate marijuana seeds is with jiffy pellets. I currently have a 100% germination rate using jiffy pellets!
Instead, we need to slowly pour 1 cup of water over them. Then wait several minutes until they expand.
You can find jiffy pellets and almost every garden store, or you can order them here. (Of course I always order them online because I am a lazy stoner.)
