WHAT IS A 1020 PLANTING TRAY?

A 1020 heavy duty, plastic growing tray is a tray with approximately 10 in X 20 in dimensions used for propagation purposes. They are heavy-duty, nestable, and perfect for bottom-watering or carrying other trays. 1020 propagation trays can be directly grown in or used as a drainage tray.

SHOULD I USE A SHALLOW OR DEEP 1020 TRAY?

Whether to use a shallow or deep 1020 tray depends on the application. Bootstrap Farmer heavy duty cell trays fit perfectly into the 1020 2.5" Trays without holes for bottom-watering and are most commonly used for that application. 1020 2.5" trays with holes or the mesh style 1020 trays are typically used for soil blocking and for growing wheatgrass.

For growing microgreens, many opt for the shallow 1020 option for top and bottom trays. They are easier to harvest as the grower can cut close to the root line without fighting the extra tray height. They are also perfect for bottom-watering applications because they provide the ideal depth for the watering requirements of most microgreens.

For most microgreens, our shallow 1 ¼ inch trays are perfect for saving on growing media and making your plants easy to harvest. 

For tall-growing crops like pea shoots, sunflowers, and wheatgrass, our deep 2.5-inch flats give your crops a little more support and space for longer growing times. The added side height keeps plants at the edge from falling over. The ability to use a deeper layer of growing media allows your plants more nutrient uptake ability and root space.

WHAT IS THE DIFFERENCE BETWEEN A 1020 WITH A MESH BOTTOM AND ONE WITH HOLES?

Growers will opt for a mesh bottom 1020 tray as it is a good product for soil blocking as it provides significantly more drainage holes for the technique. Another advantage of the mesh trays is that larger seeded microgreens like peas, wheatgrass, and barley can be grown without media using them if the seeds are at least a tiny bit larger than the mesh holes. 

HOW TO CLEAN 1020 TRAYS?

If you are using our heavy-duty, reusable trays: 

• Remove any leftover dirt and root matter

• Spray the trays off 

• Wash the mostly clean trays in hot soapy water or run them through your dishwasher. (Just remember to turn off the heated dry function)

• Rinse your trays with clean water and allow to air dry.

• For added sterilization, you can use H2O2 or a mild bleach solution.
