I HIGHLY recommend LST! I start bending my plants as soon as they are tall enough to do so (maybe 5-6 inches). If you let them veg for a week or so and keep bending the top down.. all the side branches turn and point straight up towards the lights... so.. instead of having one top on each plant and a few little side branches.. you get 7 or 8 tops per plant! This can let you keep your plant count down and helps control height (if needed) Most lights dont penetrate more than 16-18 inches into the canopy anyways.. so letting them grow super tall is pointless unless you have your plants really widely spaced and well lit. Here is a pic of a plant grown with LST.. dried weight was just under 3 ounces.. and the plant was only 16 inches tall! The second pic shows the bent main stem and the side branches shooting upwards... HIGHLY recommend this technique!!!
