I'm planning my next grow (in a couple of months) now and I'm planning to try growing from seed this time vice growing from clones. This is going to be a new experience!
Anyway, I've purchased TGA Dairy Queen and Vortex seeds.
I'm doing 100% organic soil grows and have just started trying to use "The Rev's" spikes and layers technique with my soil. So far it's water, molasses and dyna grow protekt and it is going great. The lighting is CFL for germinating, LED and CFL for veg and then more LED and par T5 side lighting for flower. Containers are .8 gallon airpots for seedlings, 3 gallon airpots for veg and finally 8 gallon airpots for flower...at least that's the plan. I have pretty fair ventilation, good humidifier (may need to get a dehumidifier for this winter, I don't know yet) with a humidistat and am having to add heat to the grow room since the advent of LEDs. Oh, and I have my wormfarm in the grow room to keep the worms happy and who knows a little extra CO2 for the girls??
What I would like to end up with is 4 female plants in 8 gallon containers (for flower). I could possibly put in two more three gallon containers if I had more than 4 female plants. Anyway, are there rules of thumb for how many seeds I should germinate to try and end up with the 4 female plants? I realize there are no guarantees, I'm just wondering about general guidelines....and of course, am quite willing to take advice on best methods.
