50-Pack Deep 3.5-inch Square Nursery Pots with Drainage Holes – Extra Tall Plant Starter Containers for Seedlings, Herbs, Succulents, and Cuttings (50 Count)

Grow Healthier Plants with Our 3.5-Inch Deep Roottrainer Nursery Pots – Designed for Optimal Root Development

Unlock the full potential of your plants with our professional-grade, 3.5-inch deep square nursery pots, specifically crafted with vertical interior grooves, or rootrainers. These carefully designed grooves encourage downward root growth, effectively preventing tangled rootballs and promoting a more robust, fibrous root system. The result? Healthier, more vigorous plants better equipped to handle temperature fluctuations and resist diseases.

Each sturdy pot is crafted from durable, reusable #6 polystyrene, ensuring consistent performance season after season. Their black finish naturally warms soil, accelerating germination and root development. With a practical tapered square shape, you can fit approximately 25% more pots per standard 10" x 20" propagation tray compared to round pots, maximizing your growing space efficiently.

Key Benefits:

• Designed with Rootrainers: Vertical grooves guide roots downward for healthier, transplant-ready plants.
• Extra-Deep Root Zone: 5.02-inch interior depth gives ample space for strong root systems.
• Superior Drainage: Four strategically placed drainage holes prevent waterlogging and promote proper aeration.
• Space-Saving Design: Tapered square shape maximizes tray capacity and improves propagation efficiency.
• Durable and Reusable: Built from rigid #6 plastic for long-term, repeated use.
• Efficient Storage: Pots nest neatly together, saving space when not in use.
