Pro Cal Thermo Pot, Squat, 3 gal

Recycled-Polyethylene Nursery Pot With Ribbed Sides, Squat, 3 Gallon

Nesting pots that stick together cost time every time you need to pull one off a stack, and thin-walled pots can crack or split under the weight of a full root ball. Pro Cal's Thermo Pot is molded from 100 percent recycled polyethylene with sturdy ribbed sides for structural strength, and its rim is shaped specifically to make de-nesting stacked pots faster and easier.

This 3-gallon Squat pot trades height for a wider base, suiting root systems that spread more than they grow deep.

Key Features & Benefits

• 100% recycled polyethylene — durable construction built from reclaimed plastic rather than virgin resin.
• Sturdy ribbed sides — adds structural rigidity so the pot resists bowing or cracking under a full root ball.
• De-nesting rim — shaped to separate stacked pots faster than a plain straight-walled rim.
• Squat and Tall profiles — choose a wider, shallower footprint or a narrower, taller one depending on bench space and root habit.

Who Should Use This Pot

Growers who want a durable, recycled-content nursery pot that de-nests quickly during transplanting, whether running a single bench of starts or a full commercial pot-filling operation.

Frequently Asked Questions

What is this pot made from?

It's molded from 100 percent recycled polyethylene, which keeps the material out of the waste stream while still providing a sturdy, ribbed-wall pot. The recycled-content construction doesn't trade away structural strength.

What does the de-nesting rim do?

The rim is shaped specifically to help separate stacked pots faster than a plain straight-walled rim would. That matters most when you're pulling pots off a tall stack repeatedly during a potting session.

What's the difference between a Squat and a Tall pot in the same gallon size?

Both hold the same volume, but a Squat pot spreads that volume across a wider, shallower footprint, while a Tall pot uses a narrower base and more height. Choose based on your root habit and how much bench or floor space you have.

Will the ribbed sides hold up under a full root ball?

Yes, the ribbing adds structural rigidity that helps the pot resist bowing or cracking under the weight of established roots and moist media. That's part of what the ribbed-wall construction is designed for.

How do I choose the right Thermo Pot size?

Match the pot size to your plant's current root mass and how long it needs to stay in that container before the next transplant or finishing stage. Sizes range from 1-gallon starts up to 5-gallon Squat and Tall finishing pots in this line.
