Can’t wait to get mine setup! Just got my new room wired up with 240v. I think I’ll be making 4 sets of 3 board setups, framing them with some aluminum angle iron. Should be easy I’m hoping lol.

Wow why the hell does that board hang off the edges so damned much? Whoa.

Fortunately when I tested the boards temps the edges of the boards were cooler than the center. I think they've just saved money on min heatsink they could get away with.

They do get hot on full blast, but some fans will help cool them. The driver gets hot too.

When I talked to them they said that the heatsinks worked so why add more? Trust me I said the same thing lol.

What is your experience as far as hang distance? At 15-20 inches I'm getting about 70,000 lux, which apparently translates to 1000-1200 ppfd

If you were at 1000-1200 pods, you're shit would be all fucked up by now without Co2. There's no way in hell you're that high. Maybe in a few spots here and there, but not average.

So this calculator is basically useless?

I hit mine with 800-1200ppfd depending on the height. I wouldn't trust a conversion. Try getting the hydrofarm par meter it works as well as the others from my testing. Last I checked it's only $100
