The product is made of UV-protected resin with easy swivel casters give you complete control over the box’s positioning, letting you take maximum advantage of moisture, temperature, and sunlight. This portable garden bed is ideal for homeowners with limited space that wish to grow plants and vegetables. Owners can take advantage of the Big City Picker’s small footprint and the mobility provided by casters to grow vegetables on their deck, balcony, and other areas with limited space. Additionally, the Big City Picker automatically waters plants by wicking water from its water reservoir. Plants rest above an aeration screen to improve the flow of oxygen to their roots, promoting faster growth. The product’s resin is a food-safe, high-density polyethylene that is BPA- and phthalate-free, which makes it safe for growing edible vegetables.
