Re: Hosted Competition - Haight Solid State vs. Hydro Grow LED
These lights use very different designs as regards cooling and viewing angle.
As you've noted, the HGL panel uses six top-mounted pc fans, while the Haight panel is passively cooled by spreading the LED's out over a larger area.
The Haight panel emits an electronic buzz that is easily heard with my ears a foot away, but fades quickly with distance. Standing three feet away, I can barely hear it. In my opinion, the noise would not be objectionable in typical grow environments.
The HGL panel does make significantly more noise, but the fans appear to be of good quality, and although my S&P exhaust fans are quiet as exhaust fans go, they pretty much drown it out. The thin tent walls do very little to muffle noise, and with the exhaust fans turned off, I can hear the panel's fans pretty much the same whether the tent is zipped or open. I don't generally run my lights with the exhaust fans turned off, so the noise from the HGL's fans is not objectionable to me.
I can't comment on how much noise multiple HGL units would make in a larger grow room, but in my opinion, a single unit would not be objectionably noisy in typical grow environments.
As far as ventilation, both tents are set up the same. Intake is passive through three flapped vents at the bottom sides and back. In the summer, the exhaust fans mounted on top of the tents exhaust through 4" ducts into the attic, but with the cold weather, I disconnected the ducts because I don't want to exhaust all the heat out of the garage. That ducting you see in that pic are the two disconnected ducts that I taped together to keep them out of the way.
thanks for your kind words and support!
if you need any other details, don't hesitate to ask
