  • What size water pump for recirculating dwc?

    Created by dan on July 24, 2018 at 2:41 pm

    Hello.

    I am wondering what the best water pump size (GPH) is best for a RDWC system that uses 5-gallon buckets. Can you please tell the best sizes for a 4 bucket, an 8 bucket and a 12 bucket system?

    Hi Dan –

    This depends on how many times you want the water to circulate water throughout the entire RDWC system per hour. I imagine once per hour would be appropriate, so a 20 GPH for the 4 bucket system, 40 GPH for the 8 bucket and 60 GPH for the 12 bucket system.

    Hope it helps!
