Here is my current SLH, SUPER LEMON HAZE. It's a sativa dominate photoperiod which would easily outgrow a tent in height. I've grown this strain 4 times, this is the first time trellising it. The pot size is 20 gallon, it's 20 inches across, the bush is 24 inches across, approx 18 inches in height at day 48 of veg, I just switched to flower the day before yesterday. I have no cut, or topped this plant at all. As you can see I have many tops, and an even canopy to start. I will be having to add a second trellis for the stretch but here is an example of using the techniques I laid out for you with a very stretchy sativa to create a bush, not a Christmas tree.
