no flushing is the process right before harvest, generally 2 weeks before harvest. I like 3 weeks.

it get's the excess nutrients out of the soil and plumps the buds up
BobBong Reviewed by BobBong on . Flush Plants are at 5 wks now and I started the flushing process to get rid of all the ferts and salts. I used 6 gallons of water on a 2 gal. pot. I was rather amazed that with the first 3 gallons, the water drained out with a heavy yellow tint and by the end of the last gallon I was draining clear water. I take it the yellow was all the yech I wanted to get rid of....right? :D Oh yah, and a pic of the children! :D Rating: 5
