i know you are supposed to replace nutes every week but how often is it necessary to clean out your buckets and reservoirs? the reason i ask is i cant picture what i am supposed to do with a lid with a giant plant attached to it while i clean the bucket. i cant imagine it is too healthy to leave your roots exposed like this for very long as well. with a scrog it seems damn near impossible. another problem would be cleaning the small parts of a recirculating system. how do you guys manage this?
