Square Black Form Pots are thin-walled plastic nursery pots for seedlings, cuttings and annuals. Their square footprint packs more pots per tray than round pots and lines up with Black Form Trays and standard 1020 flats. They come in 3.5-inch and 4.5-inch squares, each in a regular and a deeper version for longer roots. Buyers rate them highly for value and uniformity; the trade-off is light plastic that can crack if handled roughly.

Buyers give these pots high marks for value and uniformity, and many use them season after season for seedlings and cuttings. The main complaints are thin walls that crack under pressure and fast drying in small sizes.
These square black nursery pots are made of polystyrene plastic and are BPA free. They are used for annuals, vegetable cuttings and other seedlings, and for bringing potted plants to market. Each pot has bottom drainage holes.
The pots come in eight configurations. The 3.5-inch and 4.5-inch sizes are offered in regular and deep square versions for seedlings with longer root systems. They are designed for use with Greenhouse Megastore Black Form Trays, and they can also be added to traditional 1020 trays and other flats to organize plants before transplanting.
Avoid excessive heat. Do not store the pots outside, especially in direct sunlight, because extreme temperatures may cause empty containers to deform.
