Ran some more ducting and finished sealing in the bloom room last night. Also situated the stand-alone AC where its exhaust is now pumped straight outside. Temps cooled down last night to 78.5....FANTASTIC!! I'm going to cut another light on today and see if temps stay ok, and if so, we're in good shape. I'll try and post a pic or two of the setup later.
Thank you again Mr. Zogs, ya nailed it!
