Got a clone in a half dranken water 7.2 PH hoping this works out. This clone is under 8 bulb T5 should be enough power for it. I got about 2" spacing from the bulb to the top. Plant is thriving so far will update.
I like fiji water. The square container looks more refreshing.
Seriously though, i did some peppers and tomatoes in bottles a long time ago. Cut off the lid, and put it upside down in the bottle.
