Q. about , Flushing , screen, and nuts.

Hi guys, i hear about flushing but how its done and when?

screen, is screen is only that the plant will grow like a bush?

nutrients, where i live there is only biobizz, and GHE (GHE for hydro grower)
does BioBizz will do the work?

Search button is your friend! Sounds like all your questions can be answered quite easy, biobizz will be fine I'm sure. Screen is for scrogg type growing witch is control hieght and at the same time evenly distribute light across the canopy. As far as flushing, good luck figuring that out on here lol.. again search is your friend!
