I went to the hardware store to make some individual scrog screens with tomatoe cages maybe a screen I'd tack weld on the top. I take my plants out to water/flush until I find/make a water pan. Instead I found these things all ready to go. No fuss no muss, plus they were on sale! I had to bend them smaller for my small room which otherwise would not have been necessary.

See pic, please pardon the awful lighting (flash).
