If one is growing in Coco, and using bennies (Mammoth P, Great White), would a flush during transition be detrimental to those colonies, or would it be an irrelevant variable? (Sorry, I have 2 questions just sitting here, might as well use them.)
I always flush a few extra gallons a week before flower. Helps get rid of all the extra salt. I also check my ppm runoff every water. If my ppms get to high I'll add a little more water than usual. Every water should have some runoff.
Hello,I grow in RDWC and why do you want to flush? You do not need to flush in DWC except for when its time is up or Harvest time. But just from veg to flower not needed You will loose those colonies if you do flush.😊
