Hey mate👌
Is always nice to have, but no needed if you split your plant across the tent alrdy, all the do now is grow up straight, you can use a scrog to keep certain branches down if you want. everything above you can suppercrop. I mainly use a second net on my diary, so i can put my plants into different zones also. Underneath the first net is lollipopping area. Between the nets i only defoliate small amounts and top i take off all big leaves to give penetration to the middle.
