Our square plastic planting pots offer excellent surroundings for annuals, vegetable cuttings and other seedlings. Used in conjunction with Black Form Trays, these economical vacuum-molded pots are designed with performance in mind. You also can add them to traditional 1020 trays and other flats to organize plants and prepare them for transplanting.

Small black planters are available in a variety of configurations to meet different handling, labeling and bench space requirements. The 3.5-inch and 4.5-inch square nursery pots come in regular and "deep square" versions to accommodate seedlings with longer root systems. See below for the full dimensions and capacity of each pot.

Square Black Form Pots are an effective method of bringing potted plants to market. Save money with our large cases of mini black planters for commercial and teaching greenhouses.

Black Square Nursery Pot Features:

  • Made of vacuum-molded (i.e. thermoformed) polyethylene plastic
  • Bottom drainage holes
  • Eight configurations
  • For use with Greenhouse Megastore Black Form Trays

NOTE: Carrying trays must be ordered separately.

Edward (Salt Lake City, US)

Usually go through a box or two with spring sales. Holds plants well. Drains well. Labels stick well (l use printed side labels). Comes free when planting.

Gail Thurman (Columbia, US)
The pots worked well for our purposes

We appreciated being able to buy the pots in bulk, and they have been of good quality. No complaints.

M.A. (Kings Park, US)
Perfect size

These were the size I need for potting up. Shipping was very fast! The quality was less than I would prefer, but the price was right, so I'll just be gentle with them.

Paul Reising (Evansville, US)
Good pirchase

Good quality, good price, fast service. I’ll be back for more purchases


Exceeded my expectations! The pots are sturdy, and so is the form. The quality of the products is why I continue to return to Greenhouse Megastore for my gardening needs!

Dirk Hagar (South Deerfield, US)
Sturdy Little Pots

Loved the pots but they don't fit in the TRK 18350 trays very well. They are so tight in the trays you really have to cram them in to get them to fit and them it bows the tray making it difficult to pick up.


The pots were exactly what we ordered, great price and were delivered earlier than originally expected.

Square Pots

They are perfect. Nice and solid not floppy.

Jessica Ely (Chicago, US)
Great pots

I like these a lot, they aren't the ones I usually order from Greenhouse Megastore but these were the deepest I could find in the size I needed. They aren't the super thick plastic that I prefer but they aren't the cheap feeling plastic that you find other places. They will work for several years. Very pleased with them.

Marcia Goodrich (Houghton, US)

The pots came in almost no time and the quality was excellent, as was the price. What else is there to say?
