What are the dimensions of the Deep 1020 tray?
The Deep 1020 tray measures approximately 53 centimetres by 28 centimetres with a depth of 6.4 centimetres (2.5 inches). These dimensions are designed to fit standard shelving units and grow racks. The extra depth provides more room for root expansion and soil volume compared to standard shallow microgreen trays.
Why should I use a deep tray instead of a shallow microgreen tray?
Choosing a deep tray is beneficial for crops that require a longer growing period or a more substantial root system. The 6.4 centimetre depth allows for more growing media, which helps with nutrient uptake and water retention. It is also ideal for tall crops that need extra side support to prevent them from falling over the edges as they reach maturity.
Which crops grow best in the 2.5 inch deep 1020 trays?
These trays are perfect for tall or heavy crops such as pea shoots, sunflowers, wheatgrass, and fodder. They are also the preferred choice for starting larger vegetable seedlings like tomatoes, peppers, and cucumbers before they are transplanted into the garden. The depth ensures that the roots have plenty of space to develop without becoming root bound too quickly.
Can I use the Deep 1020 tray for bottom watering?
Yes, the Deep 1020 tray without holes is the industry standard for bottom watering. You can place a tray with drainage holes or a mesh tray inside this solid deep tray to create a reservoir. This method allows the plants to wick up moisture from the bottom, which keeps the foliage dry and reduces the risk of soil borne diseases and mould.
Are these trays food safe and durable?
These trays are made from high quality, food grade plastic that is free from BPA. Unlike flimsy single use trays found in many garden centres, these are heavy duty and built to last for many seasons. They are designed not to warp, crack, or break under the weight of wet soil or when being moved around the farm.
How do I clean and sterilise my Deep 1020 trays between uses?
To maintain a healthy growing environment, you should wash the trays in warm soapy water to remove any leftover debris or root matter. They are also dishwasher safe as long as the heated dry cycle is turned off. For professional level hygiene, you can sterilise them using a diluted bleach solution or food grade hydrogen peroxide to ensure no pathogens remain for the next crop.
Do these trays work with standard humidity domes?
Yes, these trays are compatible with standard 1020 humidity domes. Using a dome during the germination stage helps to maintain a consistent level of moisture and warmth. Once the seeds have sprouted and reached the top of the tray, the dome can be removed to allow for better airflow and light exposure.
What is the difference between micro herbs and microgreens when using these trays?
While microgreens are typically harvested very early, micro herbs such as basil, coriander, and parsley are often grown for a few extra weeks to develop a more intense flavour. Because micro herbs stay in the tray longer, they benefit from the extra soil depth provided by the Deep 1020 tray. This extra media gives the roots more stability and access to nutrients during their extended growth cycle.
How do I choose between a tray with holes and one without holes?
Trays with holes are used for the actual planting and growing of the seeds as they allow excess water to escape. Trays without holes are used underneath as a catchment or reservoir for bottom watering. If you are growing fodder or wheatgrass hydroponically, you may prefer the mesh or holed version to ensure the roots never sit in stagnant water.
