You will want to circulate air inside your grow room. A happy plant is a dancing plant. Your leaves and branches should be swaying gently.
This air circulation helps you plants breathe. Cannabis leaves breathe through small openings on their underside called stomata. They will “inhale” carbon dioxide and “exhale” oxygen. A fan will help move oxygen and allow fresh air to reach the stomata.
Seedling Starter Soil With Reefertilizer Start
The following recipe will make 2L of starter soil, enough to fill four Solo cups or four 4″ pots.
800ml – Potting Soil
400ml – Worm Castings
400ml – Perlite
400ml – Start Soil Conditioner
Mix these items well and add just enough water to moisten the soil. You want this soil to be moist and not wet. Grabbing a handful of soil should feel spongey and lightly hold together.
