Bubble Brothers XL 4 Pot DWC System



The Bubble Brothers XL 4 Pot DWC kit provides a perfect, easy to use hydroponic solution for those looking to grow larger plants. Based on the wildly popular original Bubble Brothers DWC system design, the Bubble Brothers XL replaces 3.5-gallon buckets with larger 5-gallon buckets and swaps out the smaller 6" lid for the higher-volume 10" lid. Each 10" bucket lid holds approximately 6.5 liters of hydroton clay pebbles or hydroponic growing medium, and features a center channel to increase root-zone aeration. With larger buckets and lids, Bubble Brothers XL 5-gallon DWC kits provide a higher capacity grow site capable of supporting larger plants. For best results, plants should be started in seed starter plugs or rockwool cubes, and transferred to the basket lids once roots are established.
