This simple cupping kit extends and is self-locking at any length, so if you have power and light kits set up in the same session, you simply measure them up and adjust the potting kit accordingly to give total accuracy.
The kit is extremely rigid and eliminates the problems of your pole dipping too low when potting heavy feed, this makes cupping in very easy indeed! Comes complete with a large and small pole pot. The number 2 section can also be cut back to fit many brands of poles.
