Want to prevent bugs/birds from getting to my inline fine exhaust & carbon filter. What type of mesh/solution do you use?

1/4" metal hardware cloth is probably what I would use (for birds/mice), but I don't know that they sell less than a roll anywhere.

Or maybe put a vent flap\backdraft damper on there. Probably the best way to go. Add cloth too.

You should be more worried of humidity spikes at lights out.

This, my shit jumps to 80 when my lights go out even with the fan running(I have like 90 gallons of soil in my grow) . Bout to hookup the dehumidifier and flip the bigguns to flower and move 5 vegging plants, 2 autos and 5 seedlings into a veg tent, the move alone should make a difference.

I just filter my intake air through the highest rated 1" thick furnace filters I can afford off the shelf. Ones that filter pollen, dander, mold, spores, etc.

Build a box, or even cut a hole in a plastic tote lid, and hookup a flange for ducting. Tent or grow room.. Then tape a new filter on every 3-4 months. It will look so grimey, and you'll be glad it isn't stuck to the plants instead.

Unfiltered cannabis is pretty nasty. There is so much DNA stuck to most homegrown buds. From pubic hairs to skin flakes (rub your leg or shake your sock in the sun).. Filtering the incoming air helps out dramatically.

I put 20 inch box fans with 20x20" furnace filters taped on all around my house, and hardly have to dust anymore.

I draw air from a protected crawlspace through a 4 inch duct filtered through a conical automotive air filter like a round f150 filter.
