Hydroponic Grow System for Indoor Lettuce – Premium Greenhouse Foam Sponge Setup
High-quality foam sponge nursery trays ensure optimal water retention and root aeration for rapid, healthy seedling growth. Durable PVC-free foam material resists mold and degradation, maintaining structural integrity through multiple growing cycles. Precision-cut planting holes (standard 1.5" spacing) accommodate most lettuce varieties with secure stem support. Modular design allows seamless integration with NFT, DWC, or aeroponic systems in greenhouses or indoor farms. Commercial-grade construction supports high-density planting (200+ seedlings per tray) for bulk production efficiency. Includes pH-neutral sponge composition to prevent nutrient lockout and promote consistent germination rates. Ideal for urban vertical farms, restaurant herb gardens, and educational hydroponic lab demonstrations. Wholesale-priced with bulk discounts – direct factory supply eliminates middleman markup for large-scale growers. Sterilized packaging ensures contamination-free delivery ready for immediate use in sterile grow environments.
