Exhausting options

Does anyone have experience venting their exhaust fans out via a chimney or septic? Just wondering, thanks!

Never did Chimney or Septic. I once tied into my Bathroom 4" exhaust ducting. If you got one maybe an option for you too.

How many plants? Are you trying to vent hoods? What size hoods? How many lights? Are you trying to vent heat or replenish fresh air?

Venting 6, 600W hooded lights for heat purposes only. Currently just venting to outside air but curious as to if the septic or chimney would be an option. thanks for any input.

i'd go through the chimney if possible. depending on where you live it might look suspicious with a bunch of steam coming out of a sewer vent on your roof for 12+ hours a day in the winter. Steam comes out of everyone's chimneys in the winter. just make sure your exhaust doesnt backdraft through any of your natural gas appliances like your water heater or furnace unless you want carbon monoxide poisoning and to kill your family and pets. also i saw this thing where a grow got busted in alaska and the dude vented out the wall horizontally and the condensation froze into this gigantic block of ice. wicked obvious. always vent to atmosphere vertically if possible
