in future instead of using 2 canopy nets try using one at desired height and keep bending the streching tips under the canopy UNTIL the stretch has finished, usually week 3 ~ 4. Might mean less plants and tips all overlapping each other but doesnt matter.
I only have 11 plants covering 2 4'X8' areas and first time growing these seeds indoor. It's really just one plant stretching too much so I won't be growing it again. I still have more than a foot to raise the lights just complaining about the stretch of the one plant.
One layer wouldn't work for me and i can get netting free. First layer is down low for lst. They wouldn't have the support the need to grow this big (some over 6ft already) if only using one net up top. I don't like to keep bending past one week of 12/12. I prefer no stress in flower. Only the left side has a second layer now as it stretched way more than expected. Both sides will get another layer (3 on the left 2 on the right) of netting as the buds form more.
The first layer down low adds support and let's me make them more bushy than tall. The bottom branches would have fallen down if not for the first layer of net.
