I tucked my plants on my last grow through a screen for almost the first 3 weeks of stretch....i do NOT recommend. if your gonna tuck, id say do it for a week and let the rest of the stretch happen upwards, I ran 8-9 week strains 10 weeks and I think i could have gotten another week out of 3 of my plants. I can only speculate that each time you weave your branches downwards, the plants have to readjust and kinda recover from the training. it slowed my flowering down.
