Understanding that farms are NOT a place for fragile objects, we decided to produce these trays for our own farm based off our own dissatisfaction with the flimsy and brittle quality of the other trays available online and in the big box stores. Tired of wasting money and putting more plastic into the landfills, we decided to produce trays that were thicker, could carry more weight and withstand even this farmers abuse. Key Features of our product: Extra Thick Green Plastic. These are meant to be reused over and over, season after season. They are perfect for microgreens, wheatgrass, fodder systems, and germination of seedlings in soil or hydroponics for hobby or commercial growers. The flat tray is a bit wider on the top and slightly tapers to the bottom. Outer dimensions: 21.25 Inches Long x 11 Inches Wide x 2.5 Inches Deep. Makes a great bundle or seed starter kit with our ultra-durable humidity domes.
