Finally found a way to tie down the stems but still having it mobile for daily water/pH checks, fills and the weekly resevoir cleaning. Command strip hooks and soft rubber ties. Put the hooks directly on the lid so it's still mobile! Was able to make the canopy more even, created a lot more light penetration through the middle, and stabilized the base. I think this will work for most of flower and I will get the plant yo yo's if they start getting top heavy.
Nice work! commend you for going for a photoperiod strain for your first grow.. wish I wouldnt have wasted months dabbling in the autoflowers. curious to see how this ends up, good luck!
