re: 1st Grow 1st Journal - White Widow & Company
LEDs can be very effective, but you should have somewhere between 35-50 watts per square foot of grow space. I'm running two LED panels now, both Mars Hydro 100x3 Old Model, and my temps stay right around 75 F, with doors closed, and exhaust running up into the attic. Ambient room temp the grow is in is 68-70F.
Larger panels, and higher wattage chips will increase the temperature, but nothing compared to similar wattage used in CFL or HID.
But, at the same time, HID lighting has been proven for decades, and if you can handle the heat produced, it's a great way to grow.
My LEDs are rated at a total of 300-340 total watts used (150-170 each), and I'm looking at 75 degrees F. When I was running 361w CFLs, temps were over 90 degrees F with the doors closed.
