Seriously...? 6 inches deep by 5 feet long, by 5 feet tall? Is that right...? Perhaps that's enough to start seedlings or clones in smaller cups or pots...but 3 gallon pots are about 11 1/2 inches wide. Unless you use a window box shaped pot, they'll run out of rootspace quickly.

The maturing ladies will need 24/7 fresh air circulation, the heat exhausted out of the room, and elbow room to grow.

IMO, chains work better than ropes. More flexibility, heat resistant and no dry-rot to eventually worry about.
