What’s up @GumbyBuds? What size constraints are you working with? Do you already have a cabinet or space to use? Computer repair shops and electronics recycling facilities are great places to get small, really quiet, power efficient fans. Get creative with the old tower PC units for ways to fasten fans, venting cords and lights to the small flat aluminum tray parts that hold chip boards. The old overlapping vents on the backs of them can be stacked in opposite directions to help create a light blocker, but allow air to vent. Probably need a pic. You can also sub aluminum ducting with the hose from a shop vac. You could even find a couple small fans to link up inside and create your own inliners.
Wait…I don’t know anything about you but…You’re trying to build this for your room and you have family in and out doing stuff and you live in an illegal state? Maybe a guerilla grow is better with a couple or several autos?
I’ll post some DIY stuff I’m working on soon. Damn fiddler in me never settles. Post up what you have.
PS go peruse @ryasco outdoor. Ritz Carlton quality, walmart quantities.
Cheers.
