The GRO Products Color GRO Vertical System (CGS) may have a small footprint, yet it will change the way you garden in a big way. The Color GRO series is the perfect way to add color and personality to your gardening space. The new planter box style combines the warmth of western red cedar with a wide array of colors. The CGS is quick and easy to assemble-it only takes a few minutes. The CGS is constructed right here in the USA with unfinished Cedar, a naturally rot and insect resistant material. The kit includes 2 removable planter boxes that can be adjusted on the CGS to accommodate different plant heights, each CG Planter Box has removable, heavy duty plastic liners with interlocking reservoir bottom. These plastic liners provide a barrier between the soil and cedar. And here's a helpful hint: you can remove the plastic liners and conveniently plant them on your potting table. All assembly hardware is included. Want to move your Color GRO Vertical System around? Add Casters and your CGS will be MOBILE! And check out the Irrigation System too!
