Product Information

About this item

• 【STACKABLE EDGE-SUPPORT DESIGN】Designed with an edge-supported structure that allows seed trays to stack securely without crushing the growing area below. Ideal for maximizing vertical space during germination, propagation, storage, and greenhouse growing applications.
• 【HELPS CREATE A DARK GERMINATION ENVIRONMENT】When stacked, seedling trays naturally reduce light exposure to support blackout germination practices commonly used for microgreens, wheatgrass, and other densely seeded crops. A practical solution for indoor growing rooms and greenhouse propagation.
• 【HEAVY-DUTY PP CONSTRUCTION】Made from extra-thick 1.8–2.0mm PP plastic for lasting durability through repeated growing seasons. The reinforced construction resists bending and warping during repeated handling, stacking, and seed-starting use.
• 【UNIFORM PERFORATED DESIGN FOR AIRFLOW & DRAINAGE】Designed with evenly distributed drainage holes across the planting tray surface to promote airflow and allow excess water to drain efficiently. Helps create a balanced growing environment for microgreens, propagation, and greenhouse applications.
• 【IDEAL SIZE FOR MICROGREENS & PROPAGATION】Measuring 23.6" × 11.8" with a shallow 1.4" profile, this growing tray provides ample space for microgreens, dense seeding, propagation projects, and hydroponic growing setups. Pair it with foam growing boards or inserts for sprouting beans, wheatgrass, and other hydroponic crops.
