Description
The Square-to-Round Pot Adaptor is a simple but useful growing accessory that allows square-bodied growing containers to be used in systems that require round pot bases — including round drainage saucers, recirculating tray systems designed for round pots, and growing rack layouts that use circular apertures or pot holders. At a fraction of the cost of replacing entire pot sets, it allows growers to adapt their existing container inventory to new growing system configurations without waste.
Square pots offer a well-known advantage over round pots of the same nominal volume: better use of tray and bench space, with less dead space between containers and more growing medium per square metre. However, many flood-and-drain trays, recirculating systems, and growing racks are designed around round pot footprints, creating a compatibility problem when growers want to use square containers. The square-to-round adaptor bridges this gap, fitting over the base of a square pot to create a round profile that sits correctly in round-pot-designed systems.
The adaptors are moulded from food-safe polypropylene, are resistant to nutrient solution chemistry, and can be cleaned and reused across multiple grow cycles. Available at very low cost — stock a supply alongside your pots and saucers so you have the flexibility to reorganise your growing layout without needing to replace containers. Available at The Horticulture Company alongside our full range of growing pots, fabric pots, saucers, and tray systems.
