Recycled post-consumer plastic. For use with microgreens, wheatgrass, seed sprouting, seed propagation, hydroponics, and soil. Extra strength BPA-free 1020 trays by Bootstrap Farmer are the new standard for both commercial and home growers. Bootstrap Farmer trays with holes are created from the same number 5 PP plastic as many household kitchenware and food storage containers, offering the same durability and proven to carry up to 50 lbs without breaking or warping. Bootstrap Farmer trays are top-rack safe in dishwashers specifically designed for multiple uses. 1020 trays with holes are more shallow than most trays, only 1.25 inches deep, offering growers more airflow into their crop to better help manage mold. 1020 trays with holes are best nested in shallow Bootstrap Farmer 1020 trays without holes. Backed by a limited 2-year warranty, Bootstrap Farmer trays are guaranteed to be free of cracks and degradation. Warranty does not cover trays left exposed in the bare sun, as the sun degrades all plastics. Dimensions: 20 in. x 10 in. x 1.25 in."
