Buy Burpee SuperSeed Windowsill 8 XL Tray – Seed Starting Tray

Description

The Burpee SuperSeed Windowsill 8 XL Tray is a narrow, single-row seed starting tray with eight extra-large cells, made for gardeners who have only a windowsill to spare. It is 11 inches long and 5 and a quarter inches wide, so it fits a narrow sill while giving each seedling a generous cell.

In our roundup, the burpee superseed windowsill 8 xl tray earned 8.7 out of 10 and was named the most space efficient tray, because it uses a single row of large cells instead of a wide block. If you want to start a few big-seeded plants without giving up bench space, this tray is a practical choice.

Key Features

Eight extra-large cells. The tray holds eight XL cells in a single row. The larger cells give big-seeded plants room to grow strong roots before they move to a larger pot or into the garden.

Narrow single-row design. The tray is 11 inches long and 5 and a quarter inches wide, with all eight cells in one row. That narrow shape fits a windowsill neatly and leaves the rest of the sill free.

Food-grade silicone. The tray is made from the same food-grade, dishwasher-safe silicone as the 36-cell SuperSeed tray. It is flexible, durable and easy to clean, so it can be washed and reused season after season.

Drainage hole in every cell. Each cell has a drainage hole, so excess water can escape and the mix does not stay waterlogged. Good drainage helps roots stay healthy while seedlings grow.

Pop-out cells for easy transplanting. Like the 36-cell tray, the flexible silicone cells let you pop seedlings out cleanly when they are ready to move, without prying or tearing roots.

Product Description

This tray is made for a specific job: starting a small number of large-seeded plants on a windowsill. Tomatoes, peppers, squash, cucumbers and sunflowers all grow fast and need room, and the eight XL cells give them that room from the start. The single row means every cell gets light from the window, instead of some cells sitting in the shade of others.

The burpee superseed windowsill 8 xl tray has no dome or light, so you add those yourself if you need them. Its strength is its shape and its material. The narrow tray fits where a wide tray cannot, the silicone cells pop out cleanly, and the tray can be washed in the dishwasher and used again next season. It is a simple, focused tray for gardeners with limited space.

Benefits

The main benefit is space efficiency. A tray that is 11 inches long and just over 5 inches wide fits a windowsill that a standard tray would overhang, yet it still gives eight plants a large cell each. That makes it a good choice for flats, small homes and anyone who starts seeds on a sill rather than a bench.

The large cells are another benefit. Big-seeded plants grow quickly, and a small cell can hold them back. The XL cells let roots develop properly before transplanting, which helps plants settle in faster outdoors. For gardeners who grow tomatoes, peppers, squash, cucumbers or sunflowers, the burpee superseed windowsill 8 xl tray gives those plants the room they need in a narrow tray.

How to Use

The burpee superseed windowsill 8 xl tray is ready to use once it is set on a windowsill or a flat surface. Fill the eight cells with seed starting mix, sow one seed per cell for large seeds such as tomatoes, peppers, squash, cucumbers or sunflowers, and water gently. The drainage hole in each cell lets excess water escape, so water little and often and let the tray drain.

Place the tray where it will get good light, and turn it occasionally so seedlings do not lean toward the window. When seedlings are ready to move, press a cell from below and pop the plug out whole, then plant it into a larger pot or into the garden. Wash the tray in the dishwasher between uses.

Why Choose

Choose this tray if you have a narrow windowsill and want to start a few large-seeded plants. It is a good fit for gardeners growing tomatoes, peppers, squash, cucumbers or sunflowers, for anyone with limited indoor space, and for gardeners who want a reusable silicone tray they can wash and use again. It was rated the most space efficient tray in our roundup, which reflects its narrow single-row shape.

Keep in mind that the tray holds only eight plants and has no dome or light, so it will not suit a large sowing or a dark room. If you want to start many seeds at once, a larger tray may suit you better, but for a few big plants on a sill the burpee superseed windowsill 8 xl tray is a strong choice.
