Here's a good visual example of the difference between low stress training and no training. The one without any training (on the left) looks strange to me because I always LST and it's rare for me to grow a straight up & down type of plant. I did bend the top of the one on the left and the sides did branches out nicely but it was after it was older. These plants were approx. 4 months old. I like to veg at least 2.5 months but usually end up flowering them out at 3-4 months. I'm trying to improve my rotation time and flower them at 2 - 2.5 months. I think it's better overall to let them mature as much as possible. I think they prefer a longer veg period and I feel it improves the potency.
The plant on the right that received the LST produced more yield. I don't top I bend... Bend em' like Beckham I say!
