I've been planning an indoor tent setup. My plan is to grow 6-12 medium sized plants. I've come up with two possibilities as for a tent setup.. advice would be awesome Plan 1: This 51.5 x 22.5 x 48.5 tent: http://www.htgsupply.com/Product-Grow-Tent---Mother-Keeper-51.5-x-22.5-x-48.5---Silver-Lined.asp I would use a 4x4 t5 array up top and supplement with two 2ft sticks vertically attached to the frame. For this one I would be able to go with a 4" vent inline fan at around 130 cfm http://www.amazon.com/Soler-Palau-TD-100X-In-line-Exhaust/dp/B0027E3Q62 with a homemade carbon filter because the flourescents dont emit as much heat. Plan 2: This 47 x 47 x 79: http://www.htgsupply.com/Product-Grow-Tent---Medium-(47x47x79)-Silver-Lined.asp This would give me room to use a 400w HID kit but would probably require more around 230 cfm http://www.amazon.com/Soler-Palau-TD-150S-In-line-Exhaust/dp/B007MRSL7I/ref=sr_1_1?s=hi&ie=UTF8&qid=1370989643&sr=1-1&keywords=td-150s to keep things from catching fire inside. I read the Soler and Palau inlines are rather silent and that's a pretty big priority for me. What do you guys think? Plan 2 probably will give me higher yields but it's around $300 more expensive.
