The idea of venting into a sewer, whether sensible or not, is to get rid of the smell by blowing the air into a system that vents away from your property. A septic system's only vent to the air is through the lids on the top of your septic tank, or through a roof vent if installed. I don't see...

I think we might be getting off topic a bit. Yes it is good to check your plumbing so as not to have sewage backups, but this thread was about venting grow room air into the sewer system. I think we've beat that horse to death by now. As uaplumber26 pointed out, venting to the sewer pipe in...

Perhaps a "swamp cooler" could be used?

-- Of course! Thanks for your comments. Like I started my post, "I'm trying to figure out the sewer system". Not being a master plumber myself, it was necessary to try to figure it out. I also could not call in a plumber to vent my grow room to the sewer. I had to try to figure it out...

one more point... about the possibility of sewage backing up into your grow room; If your exhaust is vented at floor level, I agree that if your sewer backs up you could have a problem. In stead, cut the sewer drain pipe (usually a 4" ABS plastic or metal in older buildings) up high near the...

I'm new to this. Trying to figure out the sewer system. As far as I can tell, the drains from toilets, tubs, sinks, showers, and floor drains (everything inside the house) all go down and collect together at the lowest level and out to the municipal sewer. This municipal sewer is a sealed...

Somewhere I read that the general rule-of-thumb for light coverage was 50-70w/sq ft. I have over 560sq ft I'd like to use as a veg room and a flowering room. At 70w/sq ft, that comes to about $30/day @ .065/kWh, or about $900/month. Am I doing something wrong in my calculations? How do you...

About FLIR: it only reads the heat on surfaces. It can't see through anything solid except glass. If your lights are showing bright spots outside with FLIR then it's because you have no insulation. The stealthiest way to grow to avoid FLIR detection is to build a grow room within your...
