Key Features of 12-Cell Seedling Propagation Trays with Elevated Lids

• 12 extra-deep cells (18.5 × 14.5 × 16 cm each, ~350 ml volume) – gives roots the room they need to develop strong, non-root-bound systems for high-yield plants
• Tall 18.5 cm crystal-clear elevated lid with adjustable ventilation holes – creates an ideal mini-greenhouse microclimate while allowing precise airflow control to prevent mold and fungal growth
• Heavy-duty thickened food-grade PP (polypropylene) construction – BPA-free, reusable for 8–10+ seasons without warping or cracking, even with repeated sterilization
• Reinforced drainage holes + raised bottom for perfect water management – promotes soil aeration and prevents overwatering, critical for healthy root development
• Color options: Classic Green / Black / White / Transparent lid – transparent lids maximize photosynthesis; colored lids reduce light stress for shade-tolerant seedlings
