Really, don't be nervous. There is no way you can let me down. I'm tickled you asked to grow a plant together.
In hindsight, two of each strain would have been better.. next time!
I used to love topping, bending and cracking the plants stems, they respond to the stresses great. Still do! The topping and bending can greatly increase yield. Now I grow straight up as i'm squeezing multiple plants and strains into a small space each grow. Growing straight up is probably the most simple way, it can also more clearly show what the plants can do. It might be easier to observe what they want. With a short veg the yields can also be quite good. There is some degree of training or control that can be achieved using the lights height and/or strength.
