Thanks, bizarro! Great to see you're part of the LED Growers Club too.
You know, the thing is that because we did the LST and the SCROG, the plants really expanded like crazy and filled the whole screen in the 4x4 tent - that even though 2 lights could've worked just fine, personally, we wanted the extra boost and have both plants entirely covered by the LEDs, that way all parts get the light evenly, and not more or less in different parts.
And just a safety tip here, these lights are pretty damn intense that we have to use these
safety goggles from Apollo Horticulture every time we're taking care of the girls, we take breaks in between - every 5 minutes to rest our eyes. Otherwise, prepare for headaches and feeling lightheaded for the rest of day lol.
Good luck with your grow. And don't worry, you'll be fine with 2 LEDs - they're awesome!
