Hello Why Doe,they`re called Bendz. I didn't like the idea of the mesh screen system tying the plants on to it to create the canopy, I like the freedom to take individual plants out as necessary so i bend train them outwards and late flowering i insert a stake in middle of container and support heavy laden branches with fine twine or wire. i bought 1 packet of 50 at first just to see how things went.i bought another 5 packs after trialing them and they are reusable, put on when training and forget about it the plant will fill the curve and grow sideways out of it by that time it is well established,i use them on me autos as well,bought so many packs because i think when folks discover them here possibly the shops will up the price as demand grows. i look at it as growing horizontally until space is filled then flip. noticed post getting long so. i send u info of shop if you want. regards
