Hi Bandit i was just wondering at what hight should my plants be using your light programme i have a DWC in 1.5mx1.5mx2.0m tent i have topped them once they have around 6 nodes to where i topped them and about another 4 nodes in lenght from topped area. Stand about 1 foot high im at the flowere power stage. Im also getting a second 550 for the finish cycle. Will this produce more bud at the end do you think. Thanks.
