Hydroponics is getting greener. Humboldt Wholesale has recently released their "Tray Hugger" line of reservoirs made from 90% recycled plastic content. The trays feature rounded corners, reinforced sidewalls, taller sides and stack without sticking. The California company that makes them even uses green power. Trays comes in 2x2, 3x6, 4x4 and 4x8 sizes. Look for more green products from Tray Hugger in the near future. Tray Huggers, made by gardeners for gardeners with Mother Nature in mind.
