<span class="link_user">@bankster</span>, That is a very good question and unfortunately I don't have an exact answer. I didn't bother weighing them separately for a few different reasons.
1. The flower structure was unique to each plant. The taller, non-topped pheno had bigger buds at the end but they weren't as dense as the shorter, topped plant.
2. I smoked some nugs right at trim time. Not sure which pheno I took them from.
3. Trichomes were all over the bud matter/sugar leaves of the non-topped plant, however, the nugs on the topped plant were super sticky.
Personally, I prefer the tight, dense nugs from the topped pheno. I don't think topping really affected quality since the plants were finished correctly. With that being said, I won't be tossing out the nugs from the other pheno. Both turned out top shelf in the "effects" area.
Yield is a big question but to give you an honest opinion, I would have to grow 8-10 of these side by side while topping half of them to get an average. I am assuming that the yields were similar with the non-topped plant coming out on top by a little bit.
Thanks for stopping by the garden and checking it out! Peace
<span class="link_user">@Sgtoso</span>, thanks bro, I'll be pulling #2 and #5 later today. They have a few amber trichs popping up and I don't want to lose the cerebral for the couch. What do you recommend? Peace
