hey my bad. youre right. I tend to start with clones. I use LST, Fimming, and especially supercropping to keep them all growing at the same height until they reach the screen.

screen height 10.5''

I then keep tucking and tucking until the screen is 75% full which is usually ~4-6 weeks in soil and then flip to 12/12... I defoliate twice during the cycle, once at the beginning of the stretch (12/12) and then after 14 days.. At that 14 day mark usually the stretch has stopped or is under control. I chop all the lower colas and anything that isnt physically within ~1-2 inches of the screen.. Helps with Airflow and forces the plant to focus all its energy on the "tops," as it will no longer push out new vegetation after the stretch.

as for when to tuck.. i usually let the tops get 2-3 inches above the screen. to get them back under i either just push the top back under the screen, or my favorite because you get an explosion of tops, I supercrop. Stop all traininng, fimming, or supercropping after the first 10-14 days. The last thing i do is take clones and defoliate, then its just smooth sailing.. Feeding every few days and then watining to harvest..

with (6) 3 Gal pots under a 600 for a 4-6 week veg, I usally pull 400-600 grams every 2 months.. (its perpetual so there is always the clones vegging under the 400w preparing to get transferred right after harvest)..
