Well, I've seen that the responses are varied. I know that TOPPING IS NOT LST. But anyway, I'll leave the question here. My growing space is only 90 cm tall, and I have to subtract the 20 cm for the lamp and its respective distance. I've seen many growers who use topping and get a very good response from the plants.
Anyway, I'll try to just do LST or maybe a Scrog to see how it evolves. Thanks, everyone!!!
