No worries with a scrog, the hood is only going up until finished flowering.I would prefer to just buy somthing, but the light ratchet pulleys they sell in stores are junk because you still have to reach up above the hood to release the ratchet before you can lower it. ��
Ropes and pulleys. There are a few commercial options. I used to use eyehooks through 2x4's and string, back in the day. lol
