Hey ECM Thanks for the info. I will most likely keep the fan as is this round. The air flow is nice, and it doesn't seem that noisy.Like you mentioned the plywood I went with was, to be honest on sale and the added noise protection was by accident. The plants should be a good test of my new setup. I am going to under feed them tho as I have read some of the strains were better off on the lighter side. Well see tho, things move along pretty fast.:stoned:
