Hi all
1st post here, though a long time lurker. I have 2 tents, a 3x3 Veg with an HLG 300 and a 4x4 Flower with an HLG 600. My wintertime temperatures are low and growth is slowed combined with deficiencies resulting from low transpiration. Temps outside of the tent where air is drawn from is 60-62 degrees F, and the inside tent temps at plant height raise to 70-75 with an IR gun showing leaf surface temps in the same range. I have to buy lights to use in the winter instead and like much about the 315 CMH ( Sun System or Hortilux all in 1 units ) vs a traditional MH/HPS. I would use the 315 as the sole light in the 3x3 and as a supplement light with the 600 in the 4x4.
My question is, would the 315 in the 3x3, given 60-62 starting temps, be viable? I know that leaf surface temp is more important than ambient temp and was hoping that it would bring me to mid to upper 70's ( slightly higher than the LED ) but with better leaf temps due to the IR. I realize I could get a 400 MH and probably do this or better but would prefer the 315 for several reasons - it is a flexible light and could be used to flower a SCROG or several short plants in this tent if I choose, and it is an Open rated bulb eliminating the need to run an air cooled hood for safety reasons with a MH and cluttering up the space with ducting and having to deal with the glassed reflector.
My second question is how viable is a 315 in the 4x4 as a supplemental light? I assume it will raise the temps even less due to a larger tent size but was hoping it would increase leaf temps to again mid to upper 70s for approx half of the tent ( run on the side next to the 600 ) and I could rotate the plants ( only legally allowed 3 in flower ) daily. I also realize chucking in a 400 HPS would be better but like the thought of the 315 for the safety w/o air cooled reflector reason, and for the added UV which my HLG does not have. Sorry for the long post, would love some feedback as I need to do something soon
