exhausting hot air out help

[watsupbud]

i am thinking about exhausting hot air out the home through the roof, but i was worried about steam during the winter....does anyone have a fix for this. The grow is up stairs! sighs stressssssssss

I wouldn't stress about it too much. The furnace that heats your dwelling probably creates a lot more steam than your grow does. No one will think twice about seeing steam rising from a vent on your roof in the winter. The same goes for a clothes dryer or gas water heater. The smell of tasty buds should be of much greater concern.

If you do "fix" the steam, you'll end up with a lot a water that you'll have to deal with.

vent into a large box (like a freezer would come in) and then out the roof to give the air a chance to cool? but like B said, i wouldn't worry about it to much

Even if i was venting about 6k-12k of heat?

If you're running 6-12 Kilowatts of lights, and if you're living in the house, then something like this might work well (see image). If you keep hot air from lights seperated from the damp smelly air from the grow space, then you can pipe the hot air to other parts of the house to heat it, or directly outside without worrying about steam. The much cooler, damp room exhaust can be vented into into the attic, through a cooling box if necessary, and from there to the outside. The room vents keep CO2 levels up and temp/humidity down. Two fans are used in the light cooling system to ensure lights stay cool even if one fan fails, preventing the sealed reflector hoods from overheating and becoming a potential fire hazard. Seperating light venting from room venting also allows CO2 injection to be implemented later. If you have a decent sized attic then you could vent into it and allow it to vent from there passively. An ozone generator on a timer in the attic would kill any smell that passes through the carbon filter and would prevent any mold/mildew problems resulting from the damp.
