Defoliation

No it is absolutely not necessary. If the plant would not need those leaves, it would not grow them in the first place! Just remember - Maximum amount of healthy green leaves = maximum energy production = maximum growth! I am very anti defoliation and rely on the plant knowing what is best to do, after all, they have been doing so for millenia without defoliation or dinky little humidity cribs, another of my pet hates. Have been growing for close to 40 years and plants definitely grow better not defoliated. I only ever remove yellow leaves, for by the time they are yellow, they have done their job, which is making energy for the plant to grow. Less leaves = less energy = less growth - it is that simple! Hope this helps, Organoman.

I have heard it isn't good to defoliate autos, but for my photos, I lollipop about a week or two before entering flower, then defoliate during flower at days 21 and 42. Sometimes they don't need a full defoliation, I just try to make some space for airflow.

It's never good to defoliate an auto. Try to tuck as many as you can.
