I have all 3 flowers on 150w 50-60cm space inbetween. Temp is a steady 25 celsius with humidty 45-60 approx. All done in a 80x80cm growtent. Biobizz light mix. I did root booster and after 16 days from planting in soil I did the grow boost from bac. (4 days ago) I did half the recommended measure bc these are autos. I dont measure ph. The other 2 plants which I have on the same program are doing great.
