Part 1: 1020 Microgreen Tray Specifications
Q: What are the dimensions of a standard 1020 microgreen tray?
A: A standard 1020 microgreen tray has dimensions of approximately 10 inches by 20 inches (25.4 cm x 50.8 cm) and a depth of about 2 inches (5.1 cm). These dimensions are well-suited for growing a wide variety of microgreens and are compatible with most standard growing systems.
Q: What is the difference between 1020 trays with holes and those without holes?
A: 1020 trays with holes, also known as mesh trays or drainage trays, have perforations throughout the bottom of the tray. These holes allow for better drainage and air circulation, which can help prevent waterlogging and mold growth. Trays without holes, or solid trays, are best used as a lid or cover for the mesh trays to maintain humidity and protect the growing microgreens.
Q: Can I stack 1020 trays to maximize growing space?
A: Yes, 1020 trays are designed to be stackable, allowing you to maximize your growing space vertically. When stacking trays, make sure to use trays with holes on the bottom for proper drainage and air circulation. You can then use solid trays as lids to maintain the right humidity levels for your microgreens.
Part 2: Growing Microgreens in 1020 Trays
Q: What are the most popular microgreen varieties to grow in 1020 trays? A: Some of the most popular microgreen varieties to grow in 1020 trays include:
- Broccoli
- Radish
- Sunflower
- Pea Shoots
- Arugula
- Kale
- Beet
- Basil These varieties are known for their fast growth, high yields, and versatility in culinary applications.
Q: What is the best growing medium to use in 1020 trays for microgreens?
A: The best growing medium for microgreens in 1020 trays is one that provides good moisture retention, proper drainage, and adequate support for the roots. Some popular options include:
- Coconut coir
- Potting soil
- Peat moss
- Hemp mats
- BioStrate felt
Choose a medium that is sterile, free from contaminants, and specifically formulated for microgreen production to ensure the best results.
Q: How often should I water my microgreens grown in 1020 trays?
A: The frequency of watering your microgreens in 1020 trays will depend on factors such as the growing medium, ambient temperature, and humidity levels. As a general rule, aim to keep the growing medium consistently moist but not waterlogged. Water your microgreens when the top of the growing medium begins to feel dry to the touch. Bottom watering is often preferable, as it allows the roots to absorb water as needed without disturbing the delicate shoots.
Part 3: Harvesting and Yield
Q: What is the average yield of microgreens per 1020 tray?
A: The average yield of microgreens per 1020 tray can vary depending on the variety being grown, the seeding density, and the growing conditions. However, as a general estimate, you can expect to harvest between 8 to 12 ounces (227 to 340 grams) of microgreens per 1020 tray. Some varieties, like sunflower or pea shoots, may yield slightly more due to their larger size.
Q: How long does it take to grow microgreens in 1020 trays?
A: The growth time for microgreens in 1020 trays can range from 7 to 21 days, depending on the variety and the desired size at harvest. Some fast-growing varieties, like radish or broccoli, can be ready to harvest in as little as 7 to 10 days. Others, like beet or cilantro, may take closer to 20 days. On average, most microgreens will be ready to harvest within 10 to 14 days.
Q: How do I know when my microgreens grown in 1020 trays are ready to harvest?
A: Microgreens are typically ready to harvest when they have developed their first set of true leaves, which usually occurs between 7 to 21 days after planting, depending on the variety. The true leaves are the second set of leaves that appear and resemble the leaves of the mature plant. Harvesting at this stage ensures that the microgreens have reached their peak flavour and nutrient content. Avoid waiting too long to harvest, as the microgreens may become overgrown and lose their tender texture.
Part 4: Maintaining Optimal Growing Conditions
Q: What are the best lighting options for growing microgreens in 1020 trays?
A: Microgreens require sufficient light to achieve optimal growth and colour development. Some of the best lighting options for growing microgreens in 1020 trays include:
- Natural sunlight: If you have a sunny window or greenhouse, you can use natural light to grow your microgreens.
- LED grow lights: LED lights are energy-efficient, long-lasting, and emit minimal heat, making them ideal for indoor microgreen production.
- Fluorescent tubes: Cool white or full-spectrum fluorescent tubes can provide adequate light for microgreens and are a more affordable option compared to LED lights.
Aim to provide your microgreens with 12 to 16 hours of light per day, and keep the lights about 6 to 12 inches (15 to 30 cm) above the trays.
Q: What are the best temperature and humidity levels for growing microgreens in 1020 trays?
A: Microgreens grow best in a relatively cool environment with high humidity. The optimal temperature range for most microgreen varieties is between 60 to 75°F (16 to 24°C). Temperatures above 75°F (24°C) can cause the microgreens to become elongated and leggy, while temperatures below 60°F (16°C) can slow down growth.
For humidity, aim to maintain levels between 40 to 60% to prevent the growing medium from drying out too quickly and to promote even germination. You can use a humidity dome or cover the trays with a clear plastic lid to maintain the desired humidity levels.
Q: How can I prevent mold growth in my 1020 microgreen trays?
A: Mold growth can be a common issue when growing microgreens in 1020 trays. To prevent mold, follow these tips:
- Ensure proper air circulation by using trays with holes and avoiding overcrowding.
- Maintain consistent moisture levels in the growing medium without overwatering.
- Use clean, sterile equipment and growing media to minimise the risk of contamination.
- Remove any fallen leaves or debris from the trays, as they can harbour mold spores.
- Provide adequate ventilation in your growing area to prevent stagnant, humid air. If you notice any signs of mold, remove the affected areas immediately and adjust your watering and ventilation practices accordingly.
Part 5: Cleaning and Maintenance
Q: What is the best way to clean and sanitise 1020 trays between growing cycles?
A: Properly cleaning and sanitising your 1020 trays between growing cycles is essential to maintain the health and quality of your microgreens. Follow these steps:
- Remove any remaining growing medium, roots, or debris from the trays.
- Wash the trays thoroughly with hot, soapy water and a soft brush or sponge to remove any dirt or residue.
- Rinse the trays with clean water to remove all soap residue.
- Sanitise the trays by soaking them in a solution of 1 part household bleach to 9 parts water for about 10 minutes.
- Rinse the trays again with clean water to remove any bleach residue.
- Allow the trays to air dry completely before storing or reusing them.
By following this cleaning and sanitising procedure, you can help prevent the spread of disease and ensure that your microgreens have a clean, healthy growing environment.
Q: Can I reuse the growing medium in my 1020 trays for multiple microgreen harvests?
A: In most cases, it is not recommended to reuse the growing medium in your 1020 trays for multiple microgreen harvests. Reusing the growing medium can increase the risk of disease, pest infestations, and nutrient depletion, which can negatively impact the quality and yield of your microgreens.
It is best practice to start with fresh, sterile growing medium for each new planting to ensure optimal growth and minimise potential issues. Properly dispose of the used growing medium, or if suitable, compost it for use in other gardening applications.
