I may be jumping the gun a bit but I've seen some pics of plants in flower growing up through a wide-gap mesh. Seems this is for training? What is the purpose of this mesh and how should it be used? thanks
It's called the SCROG method. There is a stickie in this section will all kinds of great information about it. Good Luck!
