We built this grow chamber specifically for breeding projects. It measures 2'x2'x6' costs about 100 bucks mainly from home depot. Its made from 6- 6ft 2x3s, poly-plastic (double sealed inside and out), 2 rolls of gorilla tape, a 60 cfm bathrom extraction fan, a hepa central a/c filter cut to sizes, a small extension cord, 2 45 watt cfls, 4 inch ducting and a 10 pound carbon filter....
There are 2 intakes in the side that are both triple hepa filtered and the bathroom extraction fan is 5x hepa filtered then exhausts out thru the carbon filter. Kept in the veg it runs with perfect conditions and with overkilled filters, no risk for accidental pollination of the sensi.... Let us know what you think
