SUNPACK® Tall Square Pot - 7in x 7in x 9in - White (50 Pack)

Frequently Asked Questions

What makes SUNPACK 7×7×9in Tall Square Pots a good choice for greenhouse and indoor growing?

SUNPACK® 7×7×9in Tall Square Pots are engineered for the demands of professional greenhouse and indoor growing environments. Their injection-molded food-grade virgin BPA-free plastic construction is free of harmful chemicals that could leach into growing media or nutrient solutions, making them safe for edible crop production. The UV-resistant composition prevents degradation from high-intensity grow lighting (HPS, CMH, LED) and direct sunlight in greenhouse settings, extending pot life across multiple crop cycles. The white exterior reflects light rather than absorbing it, helping keep root zone temperatures lower under intense lighting — a critical factor for root health and nutrient uptake. The tall 9-inch profile encourages deep vertical root development, while the 7×7in footprint provides a versatile mid-size root volume suitable for a wide range of crops from propagation through early production.

What is the approximate volume of the SUNPACK 7×7×9in Tall Square Pot, and what crops are they best suited for?

The SUNPACK® Tall Square Pot measures 7 inches long × 7 inches wide × 9 inches tall, with an approximate volume of 1.5–2 gallons. This mid-size format is well-suited for herbs, leafy greens, strawberries, compact fruiting crops, cannabis in vegetative stage, and transplant production for larger containers. The tall square profile maximizes usable root volume relative to the footprint, allowing more plants per square foot of bench or floor space compared to round pots of similar volume. The 50-pack format makes this size particularly popular for commercial propagation operations, nurseries, and greenhouse growers who need a consistent, high-volume supply of mid-size containers.

How does the drainage system work on SUNPACK Tall Square Pots, and are they suitable for hydroponic systems?

SUNPACK® Tall Square Pots feature stand-off feet with vertical drain holes that provide excellent drainage and prevent the pot base from sitting in standing water or runoff. The elevated stand-off feet also improve air circulation beneath the pot, which helps prevent root rot in high-humidity environments. These pots are well-suited for run-to-waste drip irrigation systems, hand-watering, and flood-and-drain (ebb and flow) setups commonly used in greenhouse and indoor growing. They are not designed for deep water culture (DWC) or NFT systems, which require net pots or channel-specific containers. For coco coir, perlite, or soilless media-based growing systems, SUNPACK Tall Square Pots are an excellent, cost-effective container choice.

How many pots come in a pack, and are SUNPACK pots reusable between crop cycles?

Each pack contains 50 pots, making this listing ideal for commercial greenhouse operations, nurseries, and serious hobby growers who need a consistent supply of quality mid-size containers. SUNPACK® Tall Square Pots are designed for multi-cycle reuse. Between crop cycles, remove spent growing media, rinse pots thoroughly to remove root debris and salt buildup, and sanitize with a dilute bleach solution (1:10 bleach to water) or hydrogen peroxide wash, followed by a clean water rinse and air drying. The UV-resistant, food-grade plastic construction holds up well to repeated sanitization cycles without cracking or degrading, making these pots a cost-effective long-term investment for commercial operations.
