how to clean trays.jpg

Cleaning and desinfecting the growing trays after the harvest

When growing microgreens,it’s important to keep your trays clean, and sanitized. Removing soil and other residues from your growth, such as roots and dead plants, will protect against potentially harmful germs, fungus, and damping off. If you want to have strong and healthy microgreens, you have to handle your trays and other equipment with care.  If you leave your trays with residual roots, plants, and medium, it can get stuck in your trays. This leftover dirt can harbor bacteria, and over time that can cause fungus to grow.  First after the harvest get rid of the plants and roots.  Be sure yoiu have all the roots Secondly use hot water and soap(you can add vinegar) and clean the trays thoroughly. Be sure you have removed all  the plant and soil risidue. Thirdly rinse very well and spray with( a 2tbl Hydrogen Peroxide spoon and 1liter) water mixture and just let it dry.  If possible let it dry in the sun.   Hydrogen Peroxide is a great product not only for sterilizing your trays but it has several advantages: Antibacterial – it kills bacteria cells Anti-fungal – it treats fungal growth It kills mould and mildew and prevents damping off

How to sprout soy beans

Sprouting soybeans is a relatively simple process that involves soaking the beans in water and allowing them to germinate and grow small sprouts. Here's a step-by-step guide on how to sprout soybeans: Start by selecting high-quality, organic soybeans. Ensure that they are clean and free from any debris. Measure out the desired amount of soybeans you wish to sprout. Keep in mind that the beans will roughly double in size during the sprouting process. Rinse the soybeans thoroughly under running water to remove any dirt or impurities. Place the soybeans in a large bowl or container and add enough water to completely cover them. Leave some extra room for the beans to expand. Allow the soybeans to soak for about 8 to 10 hours. It's best to do this overnight for convenience. After the soaking period, drain the water from the beans using a colander or sieve. Rinse the soybeans again with fresh water. Take a clean, damp cloth or paper towel and spread it over a plate or tray. Spread the soaked soybeans evenly over the damp cloth. Make sure they are in a single layer and not overcrowded. Cover the plate or tray loosely with another damp cloth or plastic wrap to create a humid environment for sprouting. Place the plate or tray in a warm location away from direct sunlight. Ideally, the temperature should be between 70°F to 80°F (21°C to 27°C). Twice a day, rinse the soybeans with fresh water to keep them moist. Be gentle to avoid damaging the sprouts. Continue rinsing and draining the soybeans twice a day for about 3 to 5 days, or until the sprouts have reached your desired length. The sprouting time can vary based on temperature and personal preference. The sprouts are typically ready when they reach around 1/4 to 1/2 inch in length. Once the soybean sprouts have reached the desired length, give them a final rinse and drain well. Store the sprouts in the refrigerator in a covered container or a plastic bag. They can be kept for a few days, but it's best to consume them as fresh as possible. Soybean sprouts are nutritious and can be used in salads, stir-fries, sandwiches, and other dishes. Enjoy your freshly sprouted soybeans!

Don't let temperatuture and sunlight kill your little plants

Temperature is very important for growing microgreens. The optimal temperature range for growing microgreens is between 65°F (18°C) and 75°F (24°C) This can vary depending on the type of plant, the stage of growth, and the season. For example, some microgreens like kale, lettuce, and peas can tolerate cooler temperatures, while others like basil, rocket, and amaranth prefer warmer temperatures So during the Summer period when tempertures can go into the 30's please give your little greens a place in your airconditioned place otherwise they will suffer a lot! You can put them outside in the very early morning sun or in the late afternoon sunlight. But keep in mind when temperature is plus 27C let them enjoy the A/C. They love some extra water but do not over water them!

First of all we use a weight on the green tray to trap the humidity within the tray and it will help in the germination process. Secondly the weight is pressing the seeds into the growing medium(soil) and keep them moist all troughout the germination process. Thirdly it provides some resistance for the seeds top push off of especially as they grow,  it helps them to shed their seed holes and supposedly creates a stronger base and stem because they have to fight that resistance.​ All three of these factors gives us more even germination and generally a stronger growth throughout the entire process.

Why using a weight on top of tray during germination?

Help my microgreens are growing mould!!!

Fine cobwebs between the leaves and the stem is a sign that you are growing mould in your microgreens.  Don’t be confused with the fine hair which is growing on the stems. These are called root hairs and are bright white and always appear to congregate around the root itself. Remember, they radiate out from, and are attached to, the central root. Mould on the other hand can be many different colours including grey, black and even blue. Mould will never be as bright white as the root hairs.  They will be more greyish.  Do the watering test.  Spray gentle water from above the area that you think is mould.  When they are roothairs the fluffiness will disappear.  If it stays fluffy it will be mould. What are the causes? A warm and humid environment, poor air circulation and moisture are the key ingredients for the mould spores to grow and thrive.  Mould in your microgreens is mainly caused by too much humidity. This can happen when you are continuously giving them too much water or if they are placed in a humid environment where they are not getting the right temperature and enough light.  Yes you can remove the mould!  When spotted remove all the visuable mould with a soft cloth. Wipe gently across all the microgreens I know it is challenging.  Try not to break and stems.  Remove dead and yellow leaves. Try to remove Continue by removing all dead and yellow leaves and clean out the tray so you only have the healthy microgreens left. It’s important to go through the entire tray, leave by leave, to ensure you remove any mold. You can also use a mix of Hydrogen Peroxide (3%) and water and spray gently over the grow medium . Use about 2 tablespoons of Hyd Per with half litre of water in a spray bottle. Do not overwater the microgreens and try to reduce humidity by using humidifier if you have a lot of damp in the room and open the windows to promote  airflow. Very important to keep the space where you grow your microgreen in a dry condition and with good airflow. When whole crop is affected, get rid of it and start all over again.

Signs that your little plants are not doing well!

A)….They grow mould: When you see that you have a fine cobweb between the leaves and the stem you are suffering from mould. This is not to be confused with the fine hair which is growing on the stems of some microgreens. Mould is different as it shows itself in a way that it looks like a cobweb or silvery hair which extends from the leaves. What is causing it and how to remove it from your precious plants. We have explained the difference between root hairs and mould in another post. B)….They germinate slowly Not enough darkness Your seeds need to spend some time in darkness to germinate. If you don’t put them in a dark space or/and cover with potting mix they will not germinate evenly or sometimes not at all. Solution: Put your tray in a dark place ex cupboard, basement, shed. Put another tray on top or just cover it with anything else to make it dark. Too many seeds in the tray! The trays you are using are small. When you saw too many seeds, each seed start fighting for their space, sunlight, water and nutrients in the growing medium(potting mix). Too many seeds will stop the airflow. They will just block each other from growing. C)….Are growing unevenly After your germination and black out time your crop is not evenly growing. You have tall, short microgreens and some of them didn’t came out of their shell ☹ Bummer.. This is because you sew too many seeds or they did not all have the same amount of light Too many seeds in the tray They are all fighting for air and light! Uneven distribution of light Rotate your trays so all of the microgreens get the same amount of light or use artificial growing lights. D)….Are turning yellow When your superfood greens come out of the darkness they are yellowish. This is because they did not have sunlight to produce Chlorophyl. This is a very normal process. Once in the sunlight they start to turn green. When your greens stay yellow it could be possible that you gave them to much to drink ☹ Using the wrong fertiliser can also cause the microgreens to turn yellow. E)….Are welting Not enough water to drink or just overcrowded little seedlings. Always water the from below when they are coming out the dark period. Do not overkill with adding water. It is better to add frequently water than overfilling. When there are too many seedlings in a tray they don’t have enough space to grow and there won’t be enough food for them and they will wilt ☹ F)….They don’t smell well ☹ When your crop is starting to smell it will likely to be caused by overwatering and will create mould and the stems to rotten. Do not soak them and keep them in a dry environment. High humidity that is not unusual in Queensland will contribute to unhappy microgreens. G)….Are sticking together When you have seeds grouping you have a chance that they will clump together and will not germinate. So do not put the seeds to close to eachoter to avoid this. H)….Little pests are crawling all over Sometime when you growing microgreens you can see little insects invading your crops. It may be caused by different reasons like too much water, too little water, light and heat, use of fertilizer, and more. Keep your trays away from other plants!

Growing microgreens in coconut coir, hemp mats, and potting mix each have their own pros and cons. Here's a breakdown of the advantages and disadvantages of each medium: Coconut Coir: Pros: 1. Sustainable: Coconut coir is a byproduct of coconut processing, making it an environmentally friendly choice. 2. Excellent water retention: Coir holds water well, which helps maintain optimal moisture levels for microgreen growth. 3. Good drainage: It provides adequate drainage, preventing root rot and waterlogging. 4. Neutral pH: Coir usually has a neutral pH, creating a suitable growing environment for microgreens. Cons: 1. Lack of nutrients: Coir alone is relatively inert and lacks significant nutrients. Additional fertilization might be necessary. 2. Salinity concerns: Some coir products may have excessive salt content that can negatively impact plant growth. Quality assurance is important. 3. Potential compaction: Over time, coir can become compacted, reducing its ability to hold air and water. Hemp Mats: Pros: 1. Renewable and eco-friendly: Hemp mats are made from natural hemp fibers, making them a sustainable choice. 2. Good water retention: Hemp mats retain moisture and provide hydration to growing microgreens. 3. Easy to use: Mats are convenient for sowing and harvesting as they come in pre-cut sizes, reducing the need for cutting and measuring. Cons: 1. Limited drainage: Hemp mats might retain excess water, potentially leading to root rot if adequate care is not taken. 2. Prone to mold growth: If not properly managed, the moist environment on the hemp mats can lead to mold development. 3. Nutrient deficiencies: Like coir, hemp mats generally lack significant nutrients, necessitating additional fertilization. Potting Mix: Pros: 1. Nutrient-rich: Potting mixes are often formulated to have a balanced nutrient profile, providing essential elements for microgreen growth. 2. Well-draining: Good potting mixes allow excess water to drain properly, reducing the risk of overwatering. 3. Versatility: Different potting mixes are available, catering to various plant needs and preferences. Cons: 1. Costly: High-quality potting mixes can be more expensive compared to coconut coir or hemp mats. 2. Bulkiness: Potting mixes can be heavy and less convenient when it comes to transportation and handling. 3. Environmental concerns: Some potting mixes may contain peat, a non-renewable resource, which raises environmental concerns in their production. Ultimately, the choice depends on your specific requirements, availability, and personal preferences. Combining mediums or using a different growing method like hydroponics may also be alternatives worth considering.

Storing microgreen seeds.jpg

Storing microgreens

Storing seeds properly is important to ensure their viability and germination. There are some general principles that apply to most seeds, but some seeds may have specific requirements. Here are some tips and tricks on how to store seeds long term: Dry the seeds thoroughly before storing them. Moisture can cause seeds to rot, mold, or sprout prematurely. You can dry the seeds by spreading them on a paper towel or a screen in a well-ventilated area. Avoid direct sunlight, as it can damage the seeds. The drying time may vary depending on the type and size of the seeds, but it usually takes a few days to a week. Store the seeds in airtight and moisture-proof containers. Glass jars, metal tins, or plastic bags are good options. You can also use envelopes or paper packets, but make sure to seal them well and place them inside another container. Label the containers with the name, variety, and date of the seeds. Keep the seeds in a cool and dark place. The ideal temperature for seed storage is below 40°F (4°C), which can be achieved by storing them in a refrigerator or a freezer. However, make sure to avoid temperature fluctuations, as they can reduce the seed viability. If you store the seeds in a freezer, let them thaw gradually before planting them4. You should also keep the seeds away from light, as it can trigger germination or degrade the seed quality. Check the seeds periodically for signs of damage or deterioration. Look for any mold, insects, or sprouting. Discard any seeds that are damaged or infected. You can also test the germination rate of some seeds by placing them on a damp paper towel and observing how many of them sprout within a week or two

Growing microgreens in a high temperature and humid climates.

“Keep the little seeds/pants inside when it is too hot and too humid!” Mould can be a real challenge when growing microgreens in hot and humid conditions. However, there are strategies you can use to prevent it and ensure a successful harvest. Mould thrives in stagnant air, high temperatures, and high humidity. Prioritize good ventilation and keep temperatures below 26°C (78°F). Weighing seeds during germination can restrict airflow, increasing mould risk. In hot, humid climates, remove weights after 24 hours to allow airflow. Continue germinating but in a dark, well-ventilated area. Monitor for mould carefully. Remove affected seeds promptly. Please have a look at to get an idea how mould looks like. Just continue with spraying the seeds twice a day as you would do in normal temperatures and humidities. If mold persists, use a diluted hydrogen peroxide solution (2 tablespoons per 500ml water). If it does not go away please start all over again. When growing greens in a temperature and humidity-controlled area(airconditioning) just follow the germinating and growing process as specified in growing instructions.
