Received my Solarstorm 400 earlier today. Thank you CLW for the GFP. The light is exactly what I expected. Very solid piece of equipment. I was actually extremely surprised with how quiet the thing runs. I'll be throwing in a few clones in the next couple days. Most likely going to SCROG it. Any feedback would be awesome. I'm thinking of upgrading to the S & P TD-150xs (silent series) fan. The 165cfm fan I have now is connected to a speed controller, and there is a suttle humming sound when the speed controller is less than 75%. I'll also be adding a 10-12inch Fan at the bottom blowing air straight up from the passive intake. Should help with stem strength as well as better air flow.
