I just finished up my second grow which consisted of 3 topped and 1 untopped lady. My first grow I grew 2 topped plants out.
After leaving a plant to do its own thing untopped, I noticed that the buds on my untopped plant were overall much more dense and yielded a significant amount (around 25%) more than my plants that were topped. Even the secondary branches fruited much more dense buds than the ones on the other 3 plants. It's important to note that this untopped plant was left to flower a week longer (9 weeks as opposed to
than the other plants due to the trichomes maturing slower. I also did a staggered harvest due to the height and gave the popcorn buds a bit more than a week to ripen up (10 weeks flowering total) and was impressed with the results although I probably could have left the popcorn to go even another week. All were sprouted from seed and were pineapple express feminized by G13.
Considering what I experienced, I am thinking about leaving all 4 of my plants to grow naturally this next grow to see if my results are consistent.
I see everywhere that people recommend topping to increase yields, especially with scrog grows... could the extra week of flowering been what really did it or is there any truth that untopped plants yield more dense buds?
