Buy RooTrimmer 54-Cell Deep Trays – Deep Trays for Longer Growing

Description

Some seedlings are in no hurry. Tomatoes, peppers, brassicas and many cut flowers spend six to eight weeks indoors before the weather is warm enough to move them outside, and shallow trays run out of room long before transplant day. Roots circle, dry out, or tangle, and the plants that looked strong in week three start to stall. The rootrimmer 54-cell deep trays were made for exactly that longer window. Each of the 54 cells in the tray is 2.8 inches deep, so roots have room to grow down instead of wrapping around a shallow cup, and the tray measures about 14.6 by 11.14 by 2.8 inches, a size that sits neatly on a windowsill or a standard seed starting shelf. For gardeners who start seeds early and want sturdy plants at transplant time, that extra depth makes a real difference.

Key Features

54 deep cells in one tray. The rootrimmer 54-cell deep trays hold 54 seedlings in a single tray, so you can start a full round of tomatoes, peppers, or flowers without juggling several small trays at once.

2.8 inch deep cells. Every cell is 2.8 inches deep, giving roots room to grow downward. That depth suits seedlings that stay indoors for six to eight weeks, the kind of slow starters that outgrow shallow trays fast.

Thick reusable plastic. The tray is made from thick, reusable plastic that holds its shape when full of damp mix and lifts cleanly when you move it. Wash it at the end of the season and it is ready to use again next year.

A practical footprint. At about 14.6 by 11.14 by 2.8 inches, the tray fits the usual seed starting shelf or sunny windowsill without wasting bench space, while still giving each of its 54 cells a proper depth of mix.

Open top, no dome included. No dome comes with this tray, so you are free to run it open for better airflow or pair it with a humidity cover you already own. Many growers prefer that flexibility once seedlings are up and growing.

Built for longer indoor growing. This tray is made for the long haul indoors. It is our pick for gardeners who start slow growing crops early and need a tray that keeps plants healthy until transplant day.

Product Description

The RooTrimmer 54-Cell Deep Trays are a straightforward seed starting tray built around one idea: give roots more room. The tray holds 54 cells, and each cell runs 2.8 inches deep, which is noticeably deeper than the shallow cells in many starter kits. That extra depth matters most for crops that spend a long time indoors, because roots can grow down into the mix instead of circling the bottom of the cell. The tray itself measures about 14.6 by 11.14 by 2.8 inches, so it covers a useful area without taking over your shelf, and it is made from thick reusable plastic that stands up to daily watering and handling.

There is no dome with this tray, which keeps the setup simple. You sow, water, and place the tray where your seedlings get light, and you can cover it with a dome you already own if your setup calls for one. We gave this tray an editorial rating of 8.9 out of 10. That score reflects our editorial assessment, not hands-on testing. It earned its place as pick number 9 in our seed starting trays roundup because it does one job well: it keeps longer growing seedlings healthy until they are ready for the garden.

Benefits

• Deeper roots, stronger starts. Cells that are 2.8 inches deep let roots grow down into the mix, so seedlings build a stronger root system before transplant day.
• Seedlings can stay put longer. With room for six to eight weeks of indoor growth, slow starters do not need to be moved on before they are ready.
• Reusable season after season. The thick plastic tray is made to be washed and used again, so one tray can serve your seed starting for years.
• Room for a full sowing. With 54 cells in one tray, you can start a whole bed of tomatoes, peppers, brassicas, or flowers in a single tray.
• Fits standard shelves. At about 14.6 by 11.14 by 2.8 inches, the tray sits neatly on a windowsill or a standard seed starting shelf.
• Made for the crops that take their time. It suits tomatoes, peppers, brassicas, and flowers that spend weeks indoors before moving outside.
