Germination went easy using jiffy pellets approximately 3 days. Setting this grow up for a SOG under the new 500 watt CMHs from growers choice. I have Sweet Seeds Jack 47 XL Auto starting as well but I'm going to do them in a separate journal. I grow No Till Method. I provide my plants nothing but R/O water and top dress with nutrients. The soil is my own recipe something between super soil and True Living Organics Master Mix. I supplement approximately 15% extra calcium in my soil so I can use R/O water without using a liquid nutrient to supplement the calcium. My room is an open 16 x 16 room which is just easier to keep cool over a smaller tent with intense lights in it. Walls are lined with panda film to help create the clean white look as well as reflect any light back towards the center of the room where my plants are. Yes there are 18 plants under the 500 watt CMH. Growers Choice recommends it for a 3 x 3 area for maximum yield. Since I don't mind a slightly lower yield for the plants on the outer perimeter I'm maximizing the the 4 x 4 space the light can handle for vegging. 2 plants from each strain the jack 47 xl auto and the dark devil auto will be at the perimeter of both of these light just because I hate wasting seeds and assumed 1 or 2 may fail germination I'm gonna see what they pull added in as well. My philosophy is no waste.
