it appears as though one might get a larger harvest by having more plants in smaller containers and not topping them ect. This is supposed to be true when growing with very limited space
I don't know about that..
But then again, I'm a huge believer in topping and LST.
To each their own though. Some can obtain amazing yields from multiple smaller "sphere" plants like you speak of..Hempy's, SOG, etc.
I'm one that's learned (for me) that big containers give massive root balls which in turn give "more" big buds.
Conditioning the medium with everything needed to produce healthy roots. Not just food, but Enzymes, vitamins, and root stimulants. Everything you'd "have" to do with hydro to ensure healthy roots, just adapted to drain to waste..
I'd rather give my plants tons of room and an ideally loaded medium to do whatever they wanted below ground, than have them decide they're going to go nuts, and get root bound by being stuck in a smaller container. (stress equaling less yield)
But that's just my opinion.
Plus it limits your numbers of plants..
In this day and age when people have to worry about their plant numbers.
I think the future is combining tried and true techniques, to grow healthy monster plants!
Don't know about you, but I get pretty stoked when I see people pulling a half pound or pound(s) off a single plant.
I'm like,
wiw!
