Grower's Solution Square Greenhouse Pots 3.5" x 5" Black - 25-Pack, Deep Rooting & Drainage

The Grower's Solution 3.5-inch deep square greenhouse pot is a durable, thermoformed black plastic container designed for cuttings and annuals that gives extra root depth and reliable drainage in a compact footprint.

These square greenhouse pots combine economical thermoformed construction with an improved, more pliable plastic blend to reduce cracking and extend service life. At 3.5 inches across the top and 5 inches deep, the design supports longer growth between repots and fits common propagation systems such as 1020 trays and pro-totes. Each purchase includes 25 pots with die-cut side and bottom holes for consistent drainage and airflow.

How do these pots improve seedling and cutting success?

The deeper profile gives young plants more room for root development, which delays the need to transplant and reduces root circling. Die-cut drainage points at the sides and bottom keep excess moisture away from the root zone while still retaining enough moisture for steady growth.

• 5" depth for extended root growth time
• Die-cut side and bottom holes for consistent drainage
• Square shape packs closely to save bench space
• Thermoformed walls that are flexible and less prone to cracking

Will these pots fit standard trays and propagation systems?

Yes — the 3.5" square footprint is designed to nest securely in standard 1020 trays and many pro-tote systems, making them easy to move and water in bulk. One 1020 tray accommodates up to 18 of these pots for efficient bench layout and transport.

• Compatible with 1020 bench trays (18 per tray)
• Stackable and stable for carrying and storage
• Designed to work with common greenhouse handling equipment
• Lightweight for easy bench rearrangement and propagation tasks

What makes these plastic pots more durable than standard options?

Grower's Solution updated the poly-form blend used in manufacture to increase pliability, reducing brittleness and the risk of cracks during handling or temperature swings. The vacuum-formed construction keeps production costs low while delivering consistent wall thickness and reliable performance season after season.

• New plastic blend for increased flexibility and impact resistance
• Vacuum/thermoform manufacturing for uniform, economical containers
• Reinforced edges resist chipping during loading or transport
• Black color helps moderate light and supports heat retention when needed

How should I use and care for these pots to get the most life out of them?

Clean and inspect pots between uses to remove root debris and soil; mild detergent and a rinse are usually sufficient. Store nested in a cool, shaded area to protect material from prolonged UV exposure and prevent warping.

• Rinse and brush out soil after each growing cycle
• Sanitize with mild solution if needed between batches
• Store nested off the ground in shade to preserve plastic strength
• Use with appropriate potting mixes and avoid overcompaction
