Hallo community, first thread ever. I am newb so be gentle. Lets go. My first grow attempt: I have a 6 sq ft closet in which I run a 70watt Metal Halide (daylight) and 2 x CFLs 34watt warm white.mh is 20-40cm height and cfl 5-10 max(in between plants). No ventilation/circulation. i keep one side of closet door open or half open at all times.(sometimes i refresh air manually by blowing air with a carton) I switch to day/night 11/13 light period as soon as my 3 clones are 15cm height. After 70%+ of pistils turn brown i harvest. dry weight is 13gram all plants together. does this seem a good result? is it safe to add more light or it will burn my plants? Thank you in advance.
