Pushing exhaust in to house venting?

[mamaliz]

Hi! I think this is the place to put this post--it's my first post so I'm not sure how to get the quickest response, but we'll see.

SO--I am growing in a small bedroom (12'x12"?) under 1000w HPS and 400w MH bulbs. At first I only had the 400w MH and the temperature in there was in a pretty good range. Now that I have added the 1000w, the room is very hot. I don't really have much in the way of ventilation set up--I pretty much just open the window during the day and let some fresh, cooler air in. I'm worried about temperature swings and also adequate fresh air, etc.

Here is my idea: I am thinking of using some 6" ducting to run from the 1000w hood with a fan sucking air out, and trying to direct it in to a dormant heating vent at the bottom of the wall. Has anyone tried this? I am hesitant to direct the air outside right now, and this would be relatively temporary. We are keeping the door to the room open right now and the lights make my house look a bit like a spaceship. I am growing legally, but my husband's farmer parents are going to be here in a couple of weeks and would probably be none too pleased with my choice of crops.

There are two vents in this room: both are at the bottom of the wall, one on either side of the room. I was also considering sucking air in from the other vent for a source of "fresh" (-er) air.

As I said, this would be temporary, so my main question: are there any reasons you know of NOT to do this?
Any advice or ideas would be greatly appreciated!

Unless you want your whole hose to reek of weed I wouldn't use the existing venting! How about a window AC unit and a co2 system? Or an intake fan to/from the outside or the attic? If you vent out through your roof you can probably keep things in check. plants need fresh air and temps in the mid-upper 70's. it is my understanding that mid 80's are good with a co2 system, but that is pushing it without. What are you doing about odor control? that will tip off the inlaws for sure. You'll have to get that room completely sealed for air flow and light so a co2 system would probably make a lot of sense in your situation.

sure you can vent to your house's hvac system. whether or not you do that you need to do something for smell control. it sounds like you haven't been through a flowering cycle but those plants are going to smell up your whole house if you don't do something. even though you're legal you probably don't want to advertise your grow to your neighborhood.
