Day (18 hrs) temps range from mid/high 70s - low/mid 80's depending on whether I have the cabinet open or not. I would say the average temp is around 80 with a drop to the high 60s at night (6 hrs). Each plant has 6-8 offshoot branches now that are on their 3rd or 4th internodes.
Sorry for a newb question, but why would I want stretch? Take into account that I'm working with a 5 foot tall box with reflector taking approx. 1 foot and reservoirs taking about 1 foot? With a 15 inch distance of lamp to plant, that leaves me about 21 inches for growth. If I go witha SCROG like I'm planning, I have to account for a gap of approx. 8 inches under the canopy as well. Therefore, I figure I can have tops as tall as 13 - 14 inches.
Again, I'm a newb so my questions are for education and not meant to be taken as "questioning authority". (I'm learning new stuff everyday from this site!) What do you propose I change about temps from my current averages? Also, the colors are not totally "true" as I had to photoshop the color levels a bit to brighten the pics up (hard to get good shots in HPS). They could be a little bit greener though....
