Bash... things can get a bit hairy and plants can begin to lean and fall over.. your correct to have this concern.

You should flower early 12-20 inches..

One way to keep your plants in pristine form is the following:

hang a mesh net over your plants - with large openings 2 inch X 2 inch - pull the mesh tight and let your plants grow up and through this netting... this will keep you plants in good shape...


good luck and congrats on the new system : )
