Ph is 6.5 Temp is 75 degrees in a closed room with lights 14 inch above plants. Soil is potting soil 16 qts, sand 1qt, worm castings 20 lbs, peat moss 1 lbs, perlite 4 qts, 5 oz lime mixed well. They were pick up on 11/11 and transplanted on 11/17. We have been using distilled water. We are using a 400 watt mh bulb and 2 grow lights with 4 sunlight bulbs in a room about 3 x 5. The room is sealed with an fresh air vent from outside and a vent in the ceiling to pull the air through. We have not given the plants any fertilizer as of yet. It is very cold here so the vent from outside is low to the floor and barely open.
