Right now it's an experimental time, I grew over 10 years ago in a mandatory minimum state but never experimented with different media and had never heard of kratky or Hempy either as I was just trying to do a grow and break the grow down until I was about to run out. Now I'm legal so things are different and I feel like I can play too.
The media is the massive bag of promix all purpose from home depot with additional perlite, about 75/25 respectfully, in a ~2 gallon trash can with 7/16 hole 3 inches from bottom, Hempy. Side by side with the same mix in a standard nursery pot being bottom fed and allowing roots to sit in a large reservoir. I'm also growing outdoors, 1 in ground, 1 in the above promix blend in pot in ground and 1 5 gallon Homer bucket kratky outside with a hole drilled just below the air roots so rain water won't drown it. Strains are all photo - RSC mazar-i-sharef and hashplant x northern lights. The goal of the experimentation with the kratky and the indoor plants with the oversized reservoir is to make it easy for me to pop out of town for a week with no issues, without getting into the world of pumps and massive reservoirs and all that stuff.
Oh I forgot to say, nutrients are the mega crop and the master blend tomato formula mix, running them head to head. Lot of variables I know but I'm not getting any younger and I want to do some other experiments also and breed this squat fat cabbage looking mazar pheno I was lucky enough to sprout to an auto and stabilize it..omg so much I want to do so little time to do it all in.
