inda-gro is a pro growers light if you do some real reading and stop letting your asses chat it up with your mouths you'd get off the forums buy one and see for yourself. You either vibe with something or you don't, in this case we're talking about the truth. So vibe with the real deal or don't. But i'll tell you first hand, what a feeling to let my girls do their thing keep it stupid simple and hit the gym and keep my body healthy and happy as well. Run a 9000 BTU ac and a couple fans no ducting except for the AC, and just have a great time vaping bag after bag of my previos IG harvest, i'll tell you at my young age I am quite grateful and blessed. If you want to ask stupid questions go to the newbie forum but if you want to support IG Lighting and actually learn more from some people who are in the field using and growing with Inda-gro lights then this is the place to be. I run 1260 watts and don't have to worry about heat or any issues, and i'm chillin in an old peoples apartment 8 inch inline and a presh filter and a duct muffler (silencer). Life is great, I take care of the ladies hand water them and always spend time with them we listen to lots of Francisco Tarrega and Mozart and Bach and fill up digital volcano bags and observe the short internodal growth and the dank spectrum light so the plants can take the spectrums of light THEY need when they need it. Its not my job to control them to that extent, I just share my co2 with them and love them a lot and provide the water (elixir of life) for their roots to soak up. Keep it simple. the 1260 watts 3 pro 420's covers a 4 x 8 comfortably and a 5 x 5 no prob. Anyways give thanks and stay lifted and remember, the Inda-Gro pro420 is def worth it and the more people who support Induction the sooner the industry can take off all over the states Guys who make these lights work hard and there's no doubt they deserve to do well for themselves. I know i am, take care
