Bubble Brothers 4×4 DWC System




The Bubble Brothers 4×4 DWC kit is a proven hydroponic growing system perfect for novice and experienced gardeners alike. Modeled after the original Bubble Brothers hydroponic bucket system, the Bubble Brothers 4×4 DWC offers a compact alternative with a higher volume of planting sites. It’s convenient configuration also simplifies lighting needs for the system with uniform square or smaller inline layout options. Using high-quality air stones to constantly aerate and agitate the water and nutrients in the 3.5-gallon site buckets, the Bubble Brothers 4 Pot DWC hydroponic system provides a constant supply of highly oxygenated and nutrient-rich solution for the root zone. Plant roots hang freely in the water, where they can absorb nutrients directly. Your plants will grow faster and larger than plants grown in soil mediums, thanks to the Bubble Brothers DWC system!

The Bubble Brothers 4×4 DWC system comes complete with 4 net pots for each bucket as well as hydroton clay pebble grow medium. For best results, plants should be started in seed starter plugs or rockwool stater cubes and transferred to the basket lids once roots are established.
