similar to pipe cleaners I love these, you can cut them to length. Make sure to cut them long so you can re-use them easy. About 4 bucks a pack at hydro store prices. 3 packs did about 10 15 gallon pots for me, but I tie alot of stuff. Probably will need to use more toward the end of flower.I use pipe cleaners too. Already super cheap but you can get 2 or 3 ties from each one making em last forever.
