Got 250w mh like 20 inch or so above plants @ 75% Fahrenheit 25 Celsius 50% humidity nice 6 inch inline fan blahh blahh i started like 4 weeks or 5 ago they were going sweet and i had them 6 inch above plants and they started going brown tip yellow leaf then die off weird smell. 1 outt er 4 of that bunch i kept and the one that survived is like a mini roid stay stunted in upwards growth but i've back the light way higher for start and heat and temps staying ideal is this the best way 2 do it? my biggest question i got a 400 wat hps and bulb sitting their with my hammer stoned reflector but not air vented... just inline fan connected 2 carbon filter out the man hole ducting.
1.Would you use the MH or HPS for the start differences in watts are noticeable hps bulb is a son-t agro allot of green and yellow spectrum so yeah... things seem 2 be starting nice with the 250w mh. hps will come out for flower regardless but you do reckon i will see a rapid increase in growth time if i used the HPS for VEG.
i also got about 6 going atm grabbed afew a mate started and they were done under cfls
