How refreshing to see this modern kitchen garden full of robust and healthy plants. The photo is from Jacquie's HomeGrown blog.
These are EarthBoxes and there are good reasons to buy them. The planters are made from UV resistant recycled plastic and EarthBox donates many planters for good causes through the Growing Connection, a UN agency.
Just know that sub-irrigated grow box (or bed or bucket) technology is generic rather than proprietary.
