I've been using it for a week now and I noticed the plants closest to the bags grew like crazy, I was actually surprised. Quick question though.. My bags were mostly solid white already but doesn't expire until 6/12. How did yours look when you purchased from owners?
I have a closet grow 9x9x3 and I have it vented with an inline fan from the outside flowing through to the attic. I am considering ExHale in but have a couple of questions. 1. Since plants only use CO2 during photosynthesis does this waste or in any other way harm the plants to have it working during dark hours? 2. Will the air circulation diminish the effectiveness of the bag?
Finally I live in Hawaii and so have to have ventilation because it gets up to 90 degrees in the summer in the closet so turning it off isn't possible. Thanks in advance for your replies.
The bag, I think, calms down during cooler times, so I think it runs less in the dark.
Air circulation will make the bag not helpful because if it's circulating well, then your room will be like the outside air. You're supposed to seal the room to raise the level of CO2.
FWIW, I just tried one of these things in a 4x4 tent, and I didn't see any difference really. Maybe the bag was old-it was all white. I didn't see an expiration date on it. Not disputing others' claims of success. The plants did grow in a sealed room, so I think it was putting out CO2-but CO2 more comparable to fresh air. I did not test PPM. When I went back to fresh air, everything seemed to grow at about the same pace.

Okay so i have never used co2 but i saw this product for the first time less than a week ago and the hydro guy didnt know awhole lot about it. My question is if you have your exhaust fan running doesnt the co2 get sucked out of your grow space before being used by your plants? i know co2 is heavier than air, which is obviously why this product is placed above the canopy. But im afraid if i used co2 my fan would pull it out.
How do you recommend doing this? Turn the exhaust fan off at night ?day?for how long? Once again no co2 experience so any pertinant info on it would be great.
When plants are sleeping they put out co2 a nd take in oxygen . That's why they are so perky when they wake up. They get fat breath of co2. Its a natural way of keeping o2 and co2 levels balanced. Air exchange is good anyway. When you increase co2 levels you need to increase o2 levels for repsiration. Too much co2 and plants transpire at a slower rate. Outsied air has more o2 than co2.
