Thanks, bud. I'm going to order a digital hydrometer just for the garage as well as for inside the grow tent. I'm literally near the border in San Diego, near Imperial Beach so it doesn't get too hot in the garage being less than 10 miles from the ocean, won't know how humid it is inside there until I get a proper reading.
Heat is my main concern being that I work overnights and store my father's oxygen tanks in my garage. God
forbid something bad happens while I'm at work. I've noticed that heat is a common ground with quantum boards in some reviews. The guy at Grow Gen said I would fry my plants in a 4x4 if I ran a 1000w equivalent LED and go for a minimum of 600w HPS equivalent, said it won't generate as much heat as well. I'm liking the uniformity of light distribution with bar lights from what I read on a LED company's site. Cost isn't gonna be a factor as long as the light fits in the tent and is not posing as a fire hazard. I really do appreciate all the info given here and I plan on pulling the trigger on a buy in 2 weeks so I got time to plenty of research
