Product Details The Root Spa is a Deep Water Culture system. This 5 gallon bucket system is very simple, yet it grows large plants efficiently. After a very short time, you will realize the advantages of this uniquely easy-to-use, inexpensive, and forgiving system! Pumping raw air into the nutrient solution, without the use of air stones, is not only cost-effective but is also highly effective at providing the maximum possible oxygenation for your nutrient solution. • Water tight seal to guarantee no leaks • 8" bucket basket to hold your choice of growing medium • Multi-purpose air hose delivers air from the pump to the bottom of the bucket • Air pump to oxygenate your water to encourage root growth • ½" grommet fitting • ½" elbow fitting • ¼" black tubing Media sold separately: You can use your choice of hydroponic media, such as clay pebbles, #4 perlite, rockwool mini cubes, coco chips, etc. Since this is a hydroponics system, soil should be avoided. Soil may contain dust, fungi, and bacteria, all of which can contaminate a hydroponics system. Praise for the Root Spa: “It’s easy to tell when your plants are supercharged. You don’t need any fancy meter for that—it’s visually apparent. Every time you open the door to your garden your plants almost roar at you! The speed of their development is shocking—even over a single day—they are visibly taller, fuller, bigger, and happier. I love it when my garden is cranking like this.” Specifications Attribute name Attribute value Alternate Keywords bubble bucket, DWC Barcodes 638104010931 (UPC-A) Dimensions 13.0L x 13.0W x 15.0H (EA) 48.0L x 40.0W x 68.0H (PL) Weight 6.4 lbs.
