- Availability: Depending on your location, one type of coco coir may be more readily available than the other. It’s important to choose a type that is easily accessible to you.
- Budget: Compressed coco coir bricks are generally more cost-effective than pre-mixed coco coir, making them an ideal choice if you’re on a tight budget.
Importance of Choosing the Right Type Based on Specific Needs
Choosing the right type of coco coir is essential for successful microgreen growth. Using the wrong mixture can lead to poor drainage, overwatering, and nutrient deficiencies. By considering factors such as crop requirements, availability, and budget, you can select the best option for your needs.
Caring For Your Microgreens
Water your microgreens daily, making sure not to overwater and cause waterlogging; place them in a sunny location or under grow lights for 12-16 hours per day, and fertilize as needed with a liquid fertilizer.
To make sure your microgreens thrive in coconut coir, you need to keep the growing medium moist. Overwatering can cause mold growth and lead to the death of your plants, so it’s best to avoid watering too much.
As a general rule of thumb, if the temperature is below 25 degrees Celsius, watering once per day will suffice. But if it’s hotter than that, you should water them twice a day to ensure they don’t dry out.
When it comes to watering microgreens in coconut coir, it’s important to use the right kind of water. Rainwater, bottled water, or well water are all good options because they contain natural minerals that promote plant growth.
Avoid using distilled water as this lacks essential nutrients and may not support healthy growth for your plants.
Proper lighting is crucial for growing healthy and tasty microgreens. During their approximately 10-day growth period, microgreens require a moderate amount of light to thrive.
While a sunny south-facing windowsill is ideal for growing microgreens, they are flexible in their lighting requirements. For those without access to sunlight, full-spectrum LED grow lights are available as an alternative option.
It’s important to note that during the first few days after planting, it’s beneficial to place blackout covers over your seed trays until the seeds have germinated and started pushing through the soil surface.
After this time period, you’ll want to provide around 12-16 hours of proper light each day while ensuring they’re not exposed to too much heat, which can hurt or even dry out delicate leaves.
One of the great advantages of growing microgreens in coconut coir is that they require only light fertilization. A nutrient solution with around 80 ppm of nitrogen is recommended for optimal growth.
Because microgreens are harvested young, before they produce flowers, there’s no need for heavy fertilization or chemicals. In fact, many growers prefer to use natural amendments and minerals like peat moss to create their own potting mix instead of relying on synthetic fertilizers.
Harvesting And Storage
Once your microgreens have reached their optimal growth, it’s time to harvest them by cutting them off at the base with sharp scissors or shears. Store the harvested microgreens in an airtight container or plastic bag in the refrigerator for up to a week.
Timing The Harvest
Harvesting microgreens is a crucial step that requires careful attention to timing. Depending on the variety, most microgreens are ready for harvest within 7-21 days when they reach a height of 1-3 inches.
It’s important to monitor their growth regularly and harvest them at the right time to maximize their nutrient density and flavor. You can perform a taste test or visually inspect the leaves for clues like the emergence of true leaves before harvesting.
Once you’ve harvested your microgreens, store them in an airtight container in the refrigerator to keep them fresh for longer periods.
Techniques For Harvesting
Harvesting microgreens grown in coconut coir is a simple and straightforward process. When the plants are around 3-4 inches high or when the first two leaves have unfurled, it’s time to harvest them.
A sharp pair of scissors should be used to snip the stems just above the soil level. This ensures that you get a clean cut and don’t disturb any neighboring plants. For those looking to sell their microgreens, packaging plays an essential role in maintaining freshness and quality.
It’s important to note that different types of microgreens may require specific harvesting techniques due to varying stem thicknesses and leaf shapes. Some larger seeds, such as sunflower or pea shoots, may need to be cut with garden shears instead of scissors.
Once you’ve harvested your microgreens, it’s crucial to store them properly to maintain their freshness and flavor. To extend the shelf life of your microgreens by a couple of days, it’s best to store them in an airtight container in the fridge at 39°F (4°C).
However, not all containers are suitable for storing microgreens. Moisture is the enemy of freshness when it comes to these delicate greens, so choose a container that allows ventilation and doesn’t trap excess moisture.
Another tip is to avoid washing or rinsing your microgreens until just before you’re ready to eat them since too much moisture can cause wilting and spoilage.
Troubleshooting Common Issues
If you encounter mold growth while growing microgreens in coconut coir, reduce the amount of water used and ensure proper ventilation; for pests, try using natural remedies like neem oil; if your plants are wilting, adjust their lighting or watering schedule.
One of the most common issues that growers face when growing microgreens in coconut coir is mold growth. This can be caused by excessive moisture on the surface of the growing medium or poor air circulation, leading to a buildup of bacteria and fungi.
To prevent mold growth, it’s important to ensure that your microgreens aren’t overwatered and have proper ventilation. Additionally, it’s crucial to purchase quality seeds from reputable sources and avoid overcrowding them in one area.
Aphids, whiteflies, and fungus gnats are the three most common pests that can affect microgreens grown in coconut coir. These pesky critters can quickly multiply and cause significant damage to your crop if left unchecked.
To prevent these pests from infesting your microgreen garden, it’s important to maintain a clean growing environment by regularly removing any dead or decaying plant matter.
To tackle mold growth, another common problem encountered when growing microgreens in coconut coir, you should aim to reduce humidity levels by increasing air circulation around the plants.
Overwatering is another major contributor to mold growth; hence it’s essential not to water too frequently and allow excess water to drain from trays. If you do spot signs of mold growth on your plants, remove affected plants immediately and sterilize tools used between each planting cycle with bleach solution diluted as per instructions mentioned on bottles or packets available in markets.
Wilting is a common issue that can occur when growing microgreens in coconut coir. This happens when the young plants do not receive enough moisture, causing them to droop and eventually die.
However, misting the microgreens several times a day can help rejuvenate them and prevent wilting. Additionally, some other reasons why microgreens may wilt include using too much fertilizer or placing them under direct sunlight for an extended period of time.
