Hello Rollituppers! My harvest is in 3 days, I am using a dwc system. im going to use florakleen during the last 2 days im just wondering how long i let the solution sit in my resevoir for before exchanging. The instructions for nutrient changes say to drain it after 2 hours. But says nothing for the final harvest time. i dont want to leave it in for 24 hours until i get some clarification. Thx
