Modern Home Raised Garden Bed kits are a new modular design that will simplify your gardening. Constructed of UV-Resistant High Density Polyethylene (HDPE), each kit includes 4 panels allowing you to quickly snap together a garden bed in minutes. The HDPE material will not crack, rot, warp or splinter like traditional wooden garden beds. The walls will absorb heat from the sun and help retain warm temperature needed for your plants to develop. Backed by the manufacturer 5 year limited warranty, each kit is durable and designed to last for years. The kit measures 47.25" x 47.25" x 9.8". Inside measurements are 42.1" x 42.1" x 9.8" or about 75 gallons if filled to the top.
