When staking my indoor trees that are in pots of soilless or soil, i stake each plant right at two weeks into flower. Every plant. 4 stakes per pot(5&7gals)and twist tie them up. I also clean up the bottoms at this same time and throw them into their spots, and that's that. No branches flopping around down the road
I drop the trellis down on my shorter plants in hydro at the very same time(2 weeks in). I supercrop everything to the height I want, I'll usually clean up the bottoms a bit, and slam the trellis on the canopy. Done fucking with them for the rest of the crop.
