I have designed and am preparing to build a 2'X6'X4' tent from common HomeDepot supplies(except for the Panda film). Total cost, less than $70. It took me about 3 weeks to design to my specific needs and requirements. It is completely portable. Pull down and set up as many times as you want. Should take about 30 minutes. No worries about whether the frame can support lights, vent, elec. Just a thought. If you want to check the design, here's a link: http://boards.cannabis.com/indoor-gr...critiques.html
