I am growing outdoors inside my laundry room that has my 6'x10' grow area isolated from the rest of the room. Aluminum shed is not insulated, but I have ventilation and heater, also good air circulation in the grow area that is isolated from the rest of the shed. I agree that any PH between 7.0PH and 6.0ph will work, mine stays around 6.6ph of my living soil, and water is close to the same. I use tap water that is in a 5gal. Drinking jug, with air stone for oxygenation, and that has been sitting over 24hrs. I always PH the water before I use it in a 1gal spray tank. The pics. Below are the fan leaves from 2 of my bag seeds, 15days old, which have been just topped for the second time. I will say my soil mix of 50% perilite has made a hugh difference in the growth of the plants. Much better oxygenation of the root system, they were just placed in their final pots.(12" plastic with many small drain holes.) My actual grow area is only a 2'x 3', with (1) 600w LED, which by the end of the month will have a 2nd one.
