Hi Willyweed,
Still battling the heat & yeah - waiting for Dennis!
I've kinda thrown my hands up over the heat issue & gone against my instincts for now. I've decided to grow at night when its cooler & rest them from 11 am to 5 pm when it's warmest. I can't believe with all I've done, I still can't get control of the heat!
In a 13ft run of 6" ducting, drawing from a cool 'lung room' I have 2 x 380M3/hr SVK - L1 high-output fans, exhausting through 3 x 600W coolstar lights. No 90 degree bends and yet it still ain't enough & the real warm weather isn't even here yet!
I have two more tricks up my sleeve to improve the light cooling.
1. Another SVK - L1 fan on it's way. Gonna fit this to the chimney opening to help pull it all out, should greatly improve air flow.
2. Cut another duct pipe and hole in the chimney to separately exhaust the air con unit. Currently fitted via a 'y' piece to the light cooling system.
Problem with night growing for me is the noise, so more planning & sound proofing on the job sheet for this week. Also planning to upgrade the exhaust fan & can to an 'Air Force - silent Hurricane 8" Fan & an 8" Rhino can. Next upgrade will be the A/C unit. The 'average' 9000Btu unit in there now will come down stairs for my lounge and I'm gonna buy a 15000Btu 'heat pump' A/C unit for the growroom. Oh & then a water chiller.......... and on and on - you get the picture!
Stay safe & happy growing
