Who This Is For

  • You are organizing your nursery shelf because loose square pots always tip over when you move them between lights.
  • You are focusing on root health because standard flat trays trap water and drown the bottom of your root zones.

What We Found

  • The plastic on these has a glossy flex to it, so they bend under weight rather than snapping like cheap inserts.
  • The webbed base works like a mesh tray, giving roots air from below which stops them from circling the pot bottom.

What Users Say

  • Users moving hundreds of starts to the greenhouse say the grid layout keeps their canopy organized and spill-free.
  • Nursery managers tell us they save labor hours because the smooth finish wipes clean with a quick sanitizer dunk.

Grow1 18-Site Carrier Tray for 3.25" & 3.5" Square Pots (10" x 20") 

The Grow1 18 Site Carrier Tray is an essential organization tool for nurseries and serious home gardeners. Engineered to provide a stable, space-saving foundation, this tray allows you to manage 18 individual plants with the ease of a single unit. Proudly made in the USA, it is constructed from a high-quality, glossy black plastic that is both pliable and crack-resistant, ensuring it survives the rigors of a busy growing season without the brittle snapping common in cheaper alternatives.

This carrier tray is specifically sized to hold eighteen 3.25" (0.5qt) Square Pots or 3.5" Square Black Injection Molded Pots. By locking these pots into a fixed 18-site grid, you eliminate the tipping and sliding that often occurs during transport. The design features a "web tray" style base, similar to the heavy-duty mesh web propagation tray, which provides structural support while allowing for maximum drainage. This open architecture ensures that water never pools at the bottom of your pots, maintaining the high-oxygen environment necessary for vigorous root development.

With a smooth, easy-to-clean finish, these trays are designed for repeated use. Simply sanitize between cycles to keep your nursery pathogen-free. Whether you are organizing a light shelf or moving hundreds of starts to a greenhouse, this 18-site tray offers the professional-grade stability required for efficient plant management. For those using larger containers, we also offer the 8-site carrier tray for 5.5 inch pots.

FAQ

Which specific pots are compatible with this tray?+

This tray is designed to hold (18) 3.5" Square Black Injection Molded Pots or (18) 3.25" x 3.25" x 3.5" 0.5qt Square Pots perfectly. It is also compatible with DL Item 907350.

Can I use this tray for bottom-watering?+

Because this tray features a web-style (open) base, it cannot hold water on its own. To bottom-water, place this carrier tray inside a Grow1 standard propagation tray no drain holes.

How does the web-base benefit my plants?+

The web-base ensures that the drainage holes of your pots are never blocked. This promotes superior aeration and allows for "air pruning," which prevents roots from circling and encourages a more robust root system.

Is the tray sturdy enough to be lifted when full?+

Yes. Unlike standard "thin" inserts, this carrier tray is made from a thicker, more pliable plastic designed specifically to handle the weight of 18 pots filled with wet soil or media.

What are the exact footprint requirements for my shelf?+

While often called a 10" x 20" tray because of the pots it holds, the exterior dimensions are 21.75" x 11". Ensure your shelving or flood table can accommodate these specific dimensions.
