Finally!! I got my temps down to 78 with room temps at 77...I decided to close up the booster fan blowing air into the cab & I allowed my passive intakes to do their jobs, lowered the therm the height of the plants and my temps show 78, 79 with highs of 80 and lows of 75... RH is 54%

I knew it wasn't the light...

I'm thinking of picking up a 4x8 tent to flower in, and I have my 2x4 tent I can veg in...What would you think I should pick up for lighting a 4X8 tent with LED? Or would 2 600 HIDs be better in the bloom room.

Looks like it was a pressure problem.

Good to know it's fixed

I am more glad its fixed then anything else.

I bet you are. It's always a pita when something isn't working as it should after you've done your homework, which you had.

It's a nice cabinet you built there.

That depends on the LED light, I guess. 3 x SS800w or 6 x SS400w perhaps, if you're talking about CLW lights. Personally, I would put 2 x 1000w HPS lights in a 4x8 tent for flowering. 2 x 4x4 tents with 1000w HPS each would be even better.

By August I'll be running a perpetual grow with two 4x4 for flower and one 4x4 for vegging. SME helped me plan this out about a month or so ago, and I was going through the same thought process as you.

LED are still way too expensive for bigger grow rooms. I ran the numbers, HID is about half price for comparable wattage (therefore comparable results).

I've been happy with my two SS400W but I will be retiring them to vegging light and will use 1000HID for flowering instead, just because they're so much cheaper.

I think they're cheaper AND you get better results. YMMV...

Frank what are your plans? I'm curious to hear how your set up will be situated.
