If you’re new, many suppliers have beginner kits. These kits have everything you need to start growing microgreens.
Microgreens are easy to grow. With these simple tools and a little care, you’ll have fresh greens in 2-3 weeks!
Selecting the Perfect Growing Medium
Choosing the right microgreen growing medium is key for success. You can pick from soil-based or soilless options, each with its own benefits. Let’s look at the choices to help you decide.
Soil-Based Options
Many growers like a mix of 50% coco coir and 50% organic potting soil. This mix holds moisture well and provides nutrients. You can tweak the ratio based on your needs. Other options include peat moss, perlite, and vermiculite, each adding something special to the mix.
Soilless Growing Media
For those into soilless cultivation, there are many options. Coconut coir is popular for its neutral pH and water retention. Pro-Mix HP, with mycorrhizae for root growth, is also a favourite. These sterile, soilless mixes are easy to find and use for microgreen fans.
Growing Mat Alternatives
Hemp mats are a green, compostable choice for soilless growing. They fit standard trays and are easy to compost. Specialised microgreen mats also offer ease and minimal mess during harvest.
| Growing Medium | Benefits | Considerations |
|---|---|---|
| Coco Coir + Potting Soil | Balanced moisture and nutrients | May require adjustment for specific crops |
| Pro-Mix HP | Contains mycorrhizae, widely available | Higher cost compared to basic soil |
| Hemp Mats | Sustainable, biodegradable | Limited nutrient content |
The medium you choose impacts moisture, watering, and microgreen quality. Try different mediums to see what suits your setup and favourite microgreens best.
How to Grow Microgreens: Complete Process
Microgreen farming is becoming more popular. It’s a quick way to grow greens at home. This guide will help you start your mini garden easily.
To start, soak your seeds for 6-8 hours. This is key for some seeds to germinate. Then, get your growing medium ready, whether it’s soil or a soilless mix.
Spread the seeds out evenly on your growing surface. Make sure they’re not too close together. Cover the container and put it near a window until they sprout. This usually takes 2-3 days.
After they sprout, take off the cover and let them get some light. A sunny window can give them 4-8 hours of direct light a day. If it’s too dark, a 30-watt LED light can help.
Water your microgreens every day to keep them moist. Many people use bottom watering to avoid mold. Watch them closely as they grow their first true leaves.
From planting to harvest, it takes 7-21 days. When they’re about 2 inches tall and have true leaves, they’re ready. Use clean scissors to cut just above the soil line.
| Stage | Duration | Key Action |
|---|---|---|
| Seed Soaking | 6-8 hours | Soak seeds in water |
| Planting | 1 day | Spread seeds on growing medium |
| Germination | 2-3 days | Keep covered and moist |
| Growth | 4-14 days | Expose to light, water daily |
| Harvest | 1 day | Cut when 2 inches tall |
With this simple guide, you can grow fresh, nutritious microgreens in less than a month. Happy growing!
Optimal Growing Conditions
To grow microgreens well, you need the right conditions. The best environment for them has the right amount of light, temperature, and humidity. This mix helps them grow strong and taste great.
Light Requirements
Microgreens love lots of light. They need at least four hours of direct sunlight every day. In winter, they need even more.
A sunny windowsill is perfect for your microgreen tray. If it’s too dark, LED grow lights can help. They make sure your plants get enough light.
Temperature Control
The temperature is very important for growing microgreens. The soil should be about 24°C when they start to grow. After they sprout, lower it to 16°C for the best growth.
Most microgreens grow well in room temperature. This makes them great for growing indoors.
Humidity Management
Keeping the right humidity is key. It stops mould and helps them grow. Good air flow is important to keep moisture levels right.
A well-ventilated area helps create a great environment for growing microgreens.
| Growing Condition | Optimal Range | Notes |
|---|---|---|
| Light | 4+ hours daily | More in winter |
| Temperature (Germination) | 24°C | Reduce after sprouting |
| Temperature (Growth) | 16°C | Room temperature suitable |
| Humidity | Moderate | Good ventilation needed |
By managing these conditions well, you’ll have a great place for your microgreens to grow. They’ll be healthy and taste good. You can harvest them in 5-15 days for fast-growing types, or 16-25 days for slower ones.
Watering Techniques and Management
Learning how to water microgreens is key to growing them well. The right way to water ensures they grow strong and healthy. We’ll look at the best methods and what to avoid.
Bottom-Watering Method
The bottom-watering method fills a tray under the plants with water. This lets microgreens take up water from below, helping their roots grow strong. It’s great for young plants that might get hurt by water from above.
Top-Watering Approach
Top-watering uses a spray bottle or can to water from above. It’s best for keeping the top soil moist, where seeds start to grow. Use a fine spray to avoid harming the tiny plants.
Common Watering Mistakes
Too much water can cause mould, while too little can slow growth. The goal is to keep the soil just right, not too wet or dry. Check the soil daily to adjust how often you water.
| Watering Method | Advantages | Disadvantages |
|---|---|---|
| Bottom-Watering | Promotes root growth, reduces risk of fungal diseases | May not provide enough moisture to upper soil layers |
| Top-Watering | Ensures even moisture distribution, ideal for seed germination | Can disturb delicate seedlings if not done carefully |
Microgreens in a 10×20 tray need about 44 to 74 millilitres of water each day. This can change with temperature and humidity. Knowing these watering tips will help you grow healthy microgreens.
Disease Prevention and Troubleshooting
Keeping microgreens healthy is key to a good harvest. Fungi are the biggest threat. To fight this, don’t overwater and make sure air can move freely. It’s vital to tell harmless root hairs from harmful mould when you spot problems.
Root hairs grow from the sprout base. Mould looks like a web on the seeds. Keeping things clean, using sterile tools, and having enough air can stop most diseases.
Grow microgreens in a room that’s 18-24°C to stop mould. Too cold slows growth, and too hot encourages mould. Make sure to water from the bottom to keep seeds wet and prevent uneven germination.
Remember, larger seeds are more prone to mould growth due to their larger surface area for holding mould spores.
To fight off common diseases like Pythium and Rhizoctonia solani, grow microgreens indoors or in a greenhouse. This way, you can control the climate better and avoid contamination.
| Disease | Symptoms | Prevention |
|---|---|---|
| Damping off | Pre-emergence and post-emergence plant collapse | Sterilise seeds, maintain proper humidity |
| Pythium | Wilting, yellowing leaves | Use clean tools, avoid overwatering |
| Mould | Web-like substance on seeds | Ensure good air circulation, control temperature |
By using these prevention tips and fixing problems quickly, you can have a healthy and plentiful microgreen crop.
Harvesting Your Microgreens
The art of microgreen harvesting is key to enjoying these greens at their best. Knowing when and how to cut them can greatly improve their taste and quality.
Timing Your Harvest
Microgreens are ready when they grow their first true leaves. This happens 7-21 days after planting, depending on the type. For example, Minowase Daikon Radish is ready in 10-15 days, while Bok Choy Cabbage takes up to 30 days.
Proper Cutting Techniques
Cleaning and precision are vital when cutting microgreens. Use sharp, clean scissors to cut just above the soil. This way, you get only the edible parts and keep the plant healthy. It’s wise to only take what you need to keep them fresh.
Post-Harvest Handling
After harvesting, treat your microgreens with care. If they need washing, do it gently and dry them well. Store them like cut flowers by placing the cut ends in water and refrigerating. This way, they can stay fresh for up to a week.
| Microgreen Variety | Days to Harvest | Flavour Profile |
|---|---|---|
| Minowase Daikon Radish | 10-15 days | Spicy, peppery |
| Dark Opal Basil | 15-20 days | Zesty basil flavour |
| Early Wonder Beet | 20-25 days | Slightly bitter with sweet beet notes |
| Bok Choy Cabbage | 25-30 days | Mild, slightly peppery |
Storage and Preservation Methods
Keeping microgreens fresh is key. After picking, they need gentle care to last longer. Here are top tips to keep your greens crisp and tasty.
One simple way is to use a sealed container with a damp paper towel. Put the greens in, cover with the towel, and chill in the fridge. This keeps them moist and fresh for 5-7 days.
For longer storage, some greens can be dried or frozen. But this might change their texture and nutrients. Always store them dry unless you must wash them, to prevent quick spoilage.
| Microgreen Type | Storage Method | Shelf Life |
|---|---|---|
| Pea Shoots | Sealed container with damp paper towel | Up to 3 weeks |
| Broccoli, Cabbage, Kale | Sealed container with damp paper towel | Up to 14 days |
| Mustards, Arugula, Amaranth | Sealed container with damp paper towel | Up to 10 days |
To keep greens at their best, grow them and pick as you need. This way, you always have the freshest greens. Remember, the right storage is vital for keeping microgreens fresh and full of nutrients.
