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.

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?

Black Square Form Pots are a Great Deal!

I was very happy with the size, and the quality was great! I got the 3 3/4" pots, and 18 of them fit perfectly into a tray. Delivery was prompt, and they all arrived in great shape.

N Morrison (Gladstone, US)

I loved these 3" square black pots! 18 fit nicely in a tray. I use them to prestart dahlia tubers before planting out, or to get seedlings up and growing in my greenhouse.

These transplant pots were perfect for what was needed. Good quality at a fair price.
Can't go wrong with these.
