Fully Controlled Greenhouse.
Sowing Method: Transplanting Germinants.
1 seed is sown per container 2"x7" tubes (Deepot 16) containing standard potting mix of peat moss, fir bark, perlite, and sand.
Seeds are sown 2 times the diameter to depth and are covered with media.
Flats are watered in with an automatic mist and irrigation system.
