Before you break out the duct tape, see about fans! Or plan to veg JUST long enough to gain height, and then strip the first few inches of the stem from the bottom up, so that there's no extra foliage down there to hold in the damp.
Hint: If you want to increase stretch, use your HPS in late veg/early flower, and allow a 15'F difference between night and day. Blue light and steady temps reduce stretch.
stinkyattic Reviewed by stinkyattic on . SOG technique; spacing I am in the process of building a new hydro set-up using fogponics, both dry fog and wet fog. It will be a SOG, fog to waste and I am using 2- 4'x4' trays. In laying out the lids, I was shooting for 4" stem to stem spacing using 2" net pots. I picked 4" spacing because that is what I use now with 4" rockwool blocks. What I'm finding is max number sites gives me 3 3/4" spacing or use less sites but spacing is at 4 1/2" apart. Which would be better, or what do you believe to be the best Rating: 5
