I'm just wondering if anyone has had any experience growing a sativa dominant strain in a closet or other small space. Can you tie branches towards the main stem to try to keep them from spreading out too far?
Im not fully understanding what you're saying. When a plant is LST'd the branches usually grow upwards toward the light.
I'm growing Red Dragon right now which is primarily a sativa and i've kept it around 2 feet tall through constantly LST'ing up until it stopped growing in hard flowering. I actually have my main stem actually going in a loop towards the top. I just stake a couple 1 foot bamboo sticks around the edge of my smart pot and tie them to the bamboo and put a piece of tape around the knot so that it doesn't slip.
