can anybody help me, im trying to set up a 2 pot dwc, in a 4 foot x 4 foot tent, and the scrog net is going to be very low, just above the pots, as ill have quite a low ceiling, and ive been reading about defoliating during veg and the first 3 weeks of flower, so do i have to get under the net do defoliate?? or can i defoliate from above just before weaving through the net, as it will be hard for me to get under the net to get rid of the under growth???
