Hi, nice looking plants you have there.
Theres ways to avoid heigth problem, next time have a plant on the side wich you trie out diffrent teqhnices on. I always do a combination of limb stressing and using wire to tie her down. This will help you utulize your ligth better as you can make the plant into a more receptive "bed" of flowering, instead of the classic straigth up growing colas. Adding a bit side ligth is neat too. At the beginning I grow the seedling to it have about 5 nodes, then "break" it at node 3-4, tie that down to the edge of the pot. Repeat when each new branch reaches 4-5 nodes. I always have 1 or two fresh nodes beneath the node i "break", so that the new branches can be made into fresh breakable branches. How you tie it down and if you start breaking branches already grown 5-10 nodes after breaking them initially, is up to you. This will mostly just widen your plant more. The longest i've done this during vegetive state is 4'n'ahalf months, and almost run out of space on a single plant. It was 2x2 metre wide, and 1.5 metre high when i harvested it. Basically you can shape the plant to your ligthing and growstyle. Its a very resillent plant
When it come to breaking it, its a matter of doing it a couple of times to learn how and what. I've seen people break it to much and gaffa taping it after wards, and it would still continue to grow. although break it to much and the branch dies. Break i t too little, and the thing will stretch back within a couple of days.
