Hey there, wanting to eliminate
some noise and excess power usage by exhausting my veg tent into my flower tent. My worry is light pollution. Has anybody come up with a simple light trap for connecting two tents in different growth stages? Was thinking about just using 2 elbows pointed upwards with the inside painted flat black. But I am definitely open to more elegant solutions
Responding to the light leak aspect of your post...
Because my basement is unheated and consistently 52F, when my flower tents go lights-out, I need to keep warmth in them. I use the warm air from my veg tents (24/0) to warm them.
I cut a 4x4' piece of plywood for my 4x4' flowering tents. It's actually 4x3-1/2', as I've shaved off 3" at the front and the back of the board. I put four cinder blocks in the bottom of the tent in the corners, then put the board on top of that. The board acts as a shelf, about a foot off of the bottom of the tent floor. The board is dead-even with the top of the passive intakes, so I fold the flaps on top of the board, and the intakes are underneath the board.
I then have a duct coming from the top of the veg tent that goes into a port at the bottom of the flower tent, again, underneath the board.
The warmth and passive air enter the tent below the board, and rise into the grow portion of the tent by means of the 3" gaps at the front and back.
Any light from the veg ducting or passive intake are absorbed by the cinder blocks and bottom of the board, only the air coming in enters the upper portion of the tent.
