Grower Select Round Co-Extruded Standard Pot | 4.33in - Black - 1.25pt Capacity (Case of 1850)

Light-Blocking Round Nursery Pot for the Greenhouse, 4.33in

Light reaching a young root system through a clear or thin pot wall can encourage algae growth and stress roots that are used to growing in darkness. Grower Select Round Co-Extruded Standard Pots use a co-extruded black plastic wall with a dark inner lining that blocks light from the root zone, in a sturdy, economical build made for repeated greenhouse handling.

This 4.33in pot (1.25pt capacity, case of 1850) has a 4.33in Diam x 3.75in H footprint custom fit to Grower Select carry trays built for the same round pocket size.

Frequently Asked Questions

Why does this pot have a dark inner lining?

The dark inner lining blocks light from reaching the root zone, which helps discourage algae growth on the inside of the pot wall. Roots also generally develop better without direct light exposure through a translucent pot wall.

What does co-extruded construction mean?

Co-extrusion combines two layers of plastic, typically an economical inner layer and a more durable outer layer, into a single pot wall during manufacturing. It lets the pot hold up to repeated greenhouse handling and sun exposure without the cost of an all-premium-resin pot.

Will this pot fit my existing carry trays?

This pot is custom sized to fit Grower Select carry trays built for the same round footprint, so it seats without rocking or gaps around the pocket. Confirm the specific carry tray model matches this pot's diameter and capacity before ordering at volume.

How do the different round sizes compare?

The line runs from a 4in pot at 16oz capacity up to a 6in pot at 1.5qt capacity, with 4.33in and 5in sizes in between, each fitted to a matching Grower Select carry tray. Choose the size based on the crop's root volume and how many pots need to fit per tray.

What is the difference between the 4.33in and 4.33in Wide pots?

Both share the same 4.33in diameter, but the Wide version holds a slightly larger capacity, 1.3pt versus 1.25pt, for the same footprint on the bench. Choose the Wide version when a crop needs a bit more root volume without changing the tray layout.
