I did try once and was unsuccessful. Now every time i try anything, it immediately bends at the place (which i have bandage with nylon tape. I think i will top it, will the plant have enough time to recover and produce good buds with 4 and half weeks left of flowering? It would be nice because i bought the light mover to get the light closer to the plants because i don't think the 430 is really adequate for my 4 x 3 room.
