Why do you have to get all these fancy set ups with pellets and things? Can't I just use potting soil and get some herbs and lettuce growing under lights for the winter? I have this basement and it has this shower that is never used and is kinda sketchy. The whole basement is cement (house circa 1920s) and the shower is all cement. I can't really go in the basement except for the very beginning because I'm tall and it gets shorter as you go forward. The shower thankfully is in the front.
The shower...think of it like a chemistry class or meat-packers or locker gym type shower that you don't want to really go near. I'm thinking of getting a rack system in there and getting some lettuce and herbs (chives, cilantro, basil) growing in trays. I have a TON of T5, metal halide , LEDs and all sorts of lights and timers from my various fish, reptile, saltwater tanks, etc.
SO I think I can rig up a decent little green house in the shower with lighting and I can water things quite easily with the shower head and not really worry about clean up and all.
Or this all completely inconceivable?
