Just scored a 230cfm 4inch duct fan for $18 It runs on a 12v connection, but could I hook up something like a 9v just to cut the CFM down a bit or is there such a thing as "too much ventillation"? Also, my nutes came in early from Wormsway.com. Less than $50 for the 3 bottles with 2day shipping. Really amazing place to shop around at. Here is a pic of the new toys.

And I really desperatly need to flush the soil on my 2 ladies. What should I do?
