I have a recirculating loop drip system with a rockwool buried in hydroton rocks grow medium. Each system is a three gallon net bucket housed within a five gallon bucket. Water is fed through the loop drip with the an airhose at the bottom of each five gallon bucket that pushes water up through the loop. There is always 6 to 8 inches water at the bottom of each five gallon bucket except when recirculating water back to the reservoir.
I have a friend much more experienced than I who just informed me that I should be turning the drip system off during the dark stage of flowering. I'm sure he is right as he has many years successful growing experience. I just wanted to understand the logic behind it. Any input would be appreciated. Also, does it really matter turning off the drip system in the dark stage if much of the root ball has grown through the three gallon buckets and is exposed to the standing water in the five gallon bucket or do I need to recirculate the water back to the reservoir during the dark period leavinig the five gallon buckets empty for the 12 hour dark period?
