This is a series of four videos that provide a valuable insight into the methods used by Will Allen's Growing Power in Milwaukee. This award winning urban agriculture project is a leader in the use of aquaponics and compost.
To the best of my knowledge they are not doing any growing in sub-irrigated planters (SIPs). If they were, it would be an ideal place to conduct valuable testing of compost use in SIPs.
We desperately need applied research regarding SIPs that we are not getting from the USDA Extension Program. Growing Power could be a major help in this effort.
