GrowCNanswered grow question 3 years ago Take your carbon filter and blower out of the tent so you are sucking the air out of the tent and exhausting through the filter. I don't know why you "want" to keep the filter inside but it's wasting a lot of height. Set the filter on the floor next to the tent with the opening facing up. Then put your blower on top and connect the two with a rubber Fernco plumbing fitting (rubber boot coupling). Then on the other end of your blower use another rubber coupling to some PVC pipe with a 90 degree fitting to turn the pipe into your tent. That way your blower and filter isn't taking any of your precious height.
Then rig your lights to hang from the bar in the top of your tent. The standard cable that comes with most lights leaves a lot of wasted space but with creativity you can mount your light right up against the bar.
