Square Plant Pot & Tray System Buyer's Guide

Your plants need the perfect growing environment to grow and flourish. Our square plant pots and carrying tray systems give your plants the stability, durability, and sleek design they crave. Refer to our buyer’s guide to find the perfect square pot or tray system.

NuPots™ and Square Pot Systems

Square pots offer efficiency and maximum retail shelf capacity. They range in size from 1 pint to 2 quarts with matching trays. The side-fluted NuPots™ offer side and bottom drainage, a Summit Plastic innovation that minimizes root circling.

Smooth-sided square pots allow easy labeling. They are strong, durable, and true to size. The 3 1/4″ pot holds one pint, the 4″ square pot holds one quart, and the 2-quart square holds two quarts of media. 

Punched round holes ensure good drainage support in the matching trays. Greenhouse growers will appreciate the time and labor savings that come with these systems.

Our trademarked Duo™ manufacturing process allows us to offer NuPots™ in various plant pot colors. And now, Summit proudly offers tag slots on our full-pint and full-quart NuPot™ pots. This new feature helps you stay compliant with state-mandated plant tags while maximizing valuable retail shelf space.

NuTrays™ and Square Pot Trays

You can’t have great NuPots™ without our signature NuTrays™. They are the ideal complement to our square pots and are available in 10 unique designs. All trays are available in classic black for a sleek, finished look.

Square trays are slightly recessed to protect surfaces from water damage. The raised-lip design on all four sides of the tray prevents spillage and keeps your plants neatly contained. Sturdy construction and thoughtful design make our square trays perfect for both hand-held and automated potting lines.

What should I consider when choosing a square pot or tray system?

Selecting the right size square pot or tray system is essential for the growth and development of your plants. Here are a few factors to consider when deciding:


Pot size should be based on the size of the plant. A small plant will need a smaller pot, while a larger one will need a larger one. We recommend square pots for plants 12 inches or less in height as they offer better support.


Choose a potting material that is durable and lasts for years. Our square pots are made from high-quality, durable plastic built to last.


The shape of a pot can impact plant growth. Square pots allow for more consistent growth as the plant has four equal sides to grow, while round pots can cause the plant to grow lopsided.


Square pots offer more stability than round pots and help prevent plants from tipping.


Proper drainage is essential for plant health. Our square pots have drainage holes to allow excess water to drain out, preventing root rot and promoting healthy plant growth.

Round vs. Square Pots

Not sure if a square or round system is right for you? Here’s a quick comparison:

Square Pots

Nu Pot 3


  • More stability than round pots
  • Easier to pack and ship
  • More even growth
  • Stackable for easy storage
  • Give roots more room to spread


  • Take up more space on shelves
  • May be more expensive than round pots

Round Pots



  • Round pots are cheaper than square pots
  • Occupy less space on shelves
  • Allow more sunlight to reach plants


  • Less stable than square pots
  • Roots can become tangled
  • Plants can grow lopsided


Square pots offer many benefits for both plants and growers. They automate through equipment well and provide space savings vs. equivalent round pots on benches, shipping racks, and greenhouse footprint.

We offer custom labeling and colors on our square pots and trays. This allows you to add personalized brand messaging, along with barcoding (UPC) options for efficiency at retail POS. In addition, containers can be produced in custom colors (minimums apply)
