I grow using topfed DWC in a 10 gallon tub and a LED light (rated 450w, actual ~210w draw on flower setting, ~150 on veg). I have two air stones. I tend to have 6 gallons of water to my reservoir. I grow one plant at a time from seed in my smallish tent in a closet. I don't have AC and I struggle with temperature and ventilation with my current set up.
I germinated the seed using the paper towel method. Started to crack in about 24 hours and placed her in Rapid Root plugs with the top feeding pump running nutrient rich, oxygenated water onto it after 48 hours
