All depends on the grower. If u like the idea of having more colas rather than one fat cola on top, then yes, it's very beneficial. U gotta remember tho, plants, like humans, respond differently to stress. Some plants love it and thrive, while some plants may not. All depends on the strain ur growing. So far, I have compared lst vs vertical and I must say that lst is the best way to not stress ur plants out too much.
Both plants are the exact same age, just one has been lst'd. Either way, I'm happy I get to grow my own Meds. Just keep practicing and u will get it down. Lst is not rocket science, either ur plant will love it, or she will let u know quickly that she don't. And yes, if u do not have a strong enough branch system, u may need to add some stakes to help u hold up those buds once they start putting on weight. Keep up the good work and u will be very happy, 1) cause u grew it so be proud of it, 2) it's urs to smoke. So when shes ready to harvest, pack a bowl like u never packed one before, and enjoy the fruits of ur labor. Happy growing, and aloooooooooojahz.
