    Will this DIY box grow anything?

    Hey guys! New to rollitup, I just purchased a 500w grow tent and everything is growing well in there. But I’m new to the scene and I enjoyed the set up so much I wanted to do a diy project.

    PC fan grow box

    Hey Guys. I am planning to build a Grow Box 2x2x6 (60x60x180). I need this grow to be secret tho, and need to hear your opinion, on if this is even possible. I was looking at the Spiderfarmer SF1000, since they produce less heat/watt and use no noisy fans. I am considering to buy 3 pc fans...
