Thank you Kassiopeija and KK26! Did some research, I follow you on activated carbon now! So. Do I really need one of these fancy (and pricey) set ups, or can I not just do something like the following:
I will set up my babies in 5 gallon buckets. In the garage, behind my old car that never moves. In a straight line.
I build a wooden rectangular structure around them. So, its very long, about a two feet wide of something (basically a little wider than a 5 gallon bucket) wood on top, sides and the back.
On the front, there is no wood - so it opens into the rest of the garage.
Over the opening at the front, I have a box fan that covers the opening (and then some probably). It is set to blow out from the box, thus sucking air out from the box.
Right on the other side of the fan I have trays of activate carbon set up, one over the other, with very little space in between.
So all the air is pulled out of the box with all the plants, over the activated carbon, into the garage.
Something like that might do the trick?
Thanks!!!
