I have an old hydrohut that has been working great for more than 2 years. After reading all the hype about the darkroom, I bought one of the dr150's. I really can't believe all the BS hype about the darkroom.
Have you tried to count all the F-ing pin holes in these things from the needle in the sewing machine they used to put this thing together? Yo loudblunt, the answer to the question about the light coming into the darkroom is that it very well could make a difference to a grow if the lights in the room where the darkroom sits are bright and are on during the grow's night time.
Keep drinking the Koolaid if you want but stress to a plant or a seedling isn't what I signed on for when I purchased a "professional grow tent". You stress a seed and you can produce hermys. You light the night cycle enough and consistently and you'll get hermys or you'll just throw the plant into a state of confusion or back to grow.
And lastly, my hut has steel poles, no pin holes, a place to hang my fan and my filter, and the zipper is waaaaaaaaaaaaaaaaaaaaaaaaaaay beefier. The zipper on the darkroom sucks like hell!!! I already bent two aluminum poles in my darkroom trying to hang everything. Plastic corners??? Whatever.
The product is called the DarkRoom and it isn't even dark inside! Who in the hell are you guys trying to kid? This isn't preschool! If it wasn't for the other tents killing everything, the darkroom would be some piece of shit that nobody looked at twice. Instead, you keep drinking the Koolaid -- but please stop bullshitting people who are reading your posts.
