Yo-Yo's

About Yo-Yo's
How they work
Hook one end to the tent pole or a hanging bar and the other under the branch. The spring-loaded reel takes up the slack, so the branch is supported at the right height however tall it gets. In late flower, when branches would otherwise bow under the weight, a yo-yo on each one keeps the canopy flat and open.
Alternatives
A crop support net, under Bamboo Canes & Netting, does the same job for the whole tent at once; canes and plant poles suit single stems in pots. Yo-yos are the one to reach for when a single branch needs help after the net is already in.
