Summit Plastic NuPot | Black Square - 4.375in W x 4.75in H - #5 (Case of 450)

Side-Flute Square Pot for Root-Circling Control, #5

A square pot without side venting lets roots hit the wall and start circling instead of branching, which shows up later as a root-bound plant that struggles after transplant. Summit Plastic's NuPot square pots build side-flutes into the wall alongside standard bottom drainage, an established design growers order by name for its combination of side and bottom drainage.

This Black Square, #5 pot (4.375in W x 4.75in H) holds a generous amount of media for its footprint and uses side-flutes to minimize root circling.

Frequently Asked Questions

What does the side-flute design do?

It vents the pot wall so roots are directed downward instead of circling the inside of the pot. That supports better branching once the plant moves on to its next container.

Where does this pot drain?

Through combined side and bottom drainage points, which helps manage moisture evenly across the growing medium. Bottom-only drainage tends to leave the base wetter than the rest of the pot by comparison.

What size is this pot?

#5, 4.375in W x 4.75in H. Summit sells the NuPot line by that size number, so growers can reorder the same pot consistently.

Does it hold a generous amount of media?

Yes, relative to its footprint, which supports steady root development between waterings. That capacity is part of why growers order this pot by name rather than switching sizes.
