I agree and concur with VG regarding defoliation on an outdoor plant. Really, you wanna just pluck off the stuff that the plant clearly isnât using anymore. Dead or dying yellow leaves etc. Cleanân er up so to speak. I also agree on his answer respecting the intensity of the sun in relation to an indoor grow light. Thereâs simply no comparison there. Where we may have divergent opinion however is with respect to lst. At least with regard to outdoor plants. We have to keep in mind that the sun moves - and the plant being a living thing moves with it. If the plant has been growing in its natural form since time immemorial, why would one need to change how it captures what it needs from itâs light source? Albeit, from a mobile light source that also changes in intensity throughout the day. Seems counter intuitive. I tried it once too - both it and i sucked on that grow. I donât think lst satisfies a need for, or improves upon, the plants ability to photosynthesize. Rather (and if your shooting for yield especiallyđ), youâd be best suited to topping or main lining the plant in a biiggg container. Youâll grow out a low (by comparison) and bushy monster with a massive nutrient highway for a stem that splits off like a âfork in the road to gloryâ - so to speak. The principle idea being multiple main colas as opposed to a tied back single main takeân the lions share of the nutes away from a bunch of side branches. In the alternative and to answer the question simply - let a bitch grow up, out and as high as she damn wants. Donât defoliate er but do whatâs in her best interests by pruneân Er up from time to timeđ. holy fuck, Iâm high....
