yea, im using the DR240w right now, there are countless pin holes in the material itself. more then 60, right in the middle of the material all over the tent, not even close to any seems or zippers or anything. like somebody grabbed a needle and started poking holes into the thing. the vent socks have pin holes ALLL the way around, and the zippers let out a ton of light. when i stand inside and zip it up, it is pretty light tight, except for the aforementioned pin holes, but there arent any major leaks where it would fuck up the plants flowering. but that might be due to the fact that the room im using it in only has a single 30w cfl to light it with, and its kinda far from the surface of the tent. all in all, for the 450 bux i paid for this tent, i did expect better, and i do feel a little let down. ohh yea, i could hang from the inside of the tent, but im a light weight (130 pounds soaking wet), however, you can kinda tell that the poles are kinda cheap. the zipper is big and feels strudy, but like i said it leaks light like a mother fucker.
