Reusable, stackable, and built to last, this 20-pack helps you scale your growing operation efficiently. Ideal for home growers, urban farmers, and commercial starters.

• ‌Optimized 5" Height for Grow Racks Designed with a scientifically balanced 5-inch vertical profile that maximizes vertical clearance on standard shelving units. This specific height provides the ideal internal growing volume for seedlings and clones to develop, ensuring efficient space utilization in multi-layer grow systems without wasting shelf height.
• Universal Compatibility with 1020 Trays Engineered with a precise rim design to ensure a secure, airtight seal on standard 10x20 inch propagation trays, specifically suitable for heavy-duty bottom trays and cell plug inserts. This tight fit creates a stable microclimate essential for consistent germination across the entire tray.
• 20-Pack High-Volume Commercial Set A bulk quantity bundle designed for continuous harvest cycles and large-scale propagation. Providing 20 reusable domes in one package offers a scalable and consistent solution for expanding nurseries, microgreens businesses, and hydroponic systems requiring uniform equipment.
• Dual-Vent Humidity Management Features adjustable rotary vents that allow precise regulation of airflow and internal temperature. This control system is critical for the "hardening off" process, enabling growers to gradually acclimate seedlings to ambient conditions and help reduce excess moisture buildup.
• High-Transparency Reinforced Material Manufactured from extra-thick, crystal-clear plastic that withstands repeated handling and high-humidity environments. The high light transmission material supports efficient photosynthesis, while allowing growers to easily observe general plant development without disturbing the ecosystem.
