The Ultimate Professional Guide for Innovative Microgreens Systems & Sustainable Harvesting
Growing microgreens without soil has long been more than just a trend among urban gardeners and foodies. More and more professionals, agricultural businesses, gastronomy startups, and ambitious indoor farmers are discovering the enormous potential of microgreens systems – completely without traditional soil. Whether you want to grow microgreens professionally, are looking for the best methods for resource-efficient harvesting, or want to know how to grow microgreens in glass and thus open up completely new worlds of taste: In this comprehensive specialist article, you’ll find all relevant basics, cutting-edge methods, and practical professional tips. The goal: Make your microgreens project – from sprouts, microgreens & Co. to superfoods – a sustainable and economically successful venture.
Microgreens – What Are They Actually?
Microgreens are the young seedlings of vegetables, herbs, and grains that are harvested after just a few days and contain particularly high levels of vitamins, enzymes, and secondary plant compounds. They are considered true superfoods and are equally in demand in upscale gastronomy, retail, and among conscious consumers. Unlike sprouts, microgreens are harvested after germination with stem and leaf greens – this provides intense flavor, high nutrient density, and attractive appearance.
The key point: Growing microgreens yourself is possible both on a professional scale and at home, in small spaces, and without traditional soil.
Growing Microgreens Without Soil – Advantages, Systems & Future Potential
The trend of growing microgreens without soil is establishing itself worldwide – for good reasons:
- Maximum hygiene: No risk of soil mold, fungal diseases, or unwanted microorganisms.
- Precise nutrient control: Exact dosing and control of all growth factors possible.
- Space and resource saving: Perfect for indoor farms, vertical farming, and urban agriculture.
- Year-round production: Independent of weather, season, and location.
- Economic efficiency: Faster harvest cycles, less risk of failure, better planning and scalability for professionals.
The microgreens cultivation systems without soil range from simple germination trays to hydroponic and aeroponic systems to high-tech vertical farms. Innovative growing microgreens in glass concepts, as used by urban gardening startups and specialty restaurants, are also increasingly being applied.
Growing Microgreens Professionally – Requirements, Planning, and Success Factors
Anyone who wants to grow microgreens professionally needs more than just good seeds. The focus is on the right technology, climate control, lighting, nutrient supply, and hygiene concepts. Successful microgreens operations rely on standardized processes, automation, and digital control systems to ensure consistently high yields and quality.
- Location & Space: Space requirements are minimal, especially with vertical farming. Large quantities of microgreens can be produced even in just a few square meters.
- System Selection: Hydroponics, aeroponics, germination trays, multi-level shelving, or glass culture – the choice depends on product range, space, budget, and target market.
- Lighting: LEDs with optimal light spectrum are crucial for fast, compact growth and high vital substances.
- Nutrient Solution: The quality and composition of the nutrient solution is the key to color, taste, and nutrient density.
- Filter and Climate Technology: Professional air filters and climate control ensure hygiene, stable conditions, and reduce the risk of fungal infestation and failures.
Our experts advise you in planning and optimizing your professional microgreens facility – from the first germination test to scalable high-tech systems.
Growing Microgreens Without Soil – Methods, Systems & Comparison
Below you’ll find an overview of proven methods for growing microgreens without soil – from small DIY approaches to commercial systems:
- Hydroponics: Microgreens grow on an inert mat (e.g., hemp fiber, coconut, rockwool) or a net. The roots are bathed or sprayed with a nutrient solution.
- Aeroponics: Here the roots “hang” freely in the air and are regularly misted with nutrient fog – this increases oxygen uptake and growth.
- Germination Jars & Glass Culture: Particularly popular with food startups and urban gardeners. Sprouts, microgreens & Co. are grown directly in glass, usually on a sieve.
- DIY Germination Trays & Trays: Practical for small quantities or test runs. Place sprouting mat on a tray, moisten regularly, and harvest after a few days.
Anyone who wants to grow microgreens or grow microgreens themselves will find the right solution for every scale and requirement with these methods.
Microgreens Growing Instructions – Step by Step to Success
1. Selection of Microgreens Varieties
- Popular varieties for soilless cultivation: Radish microgreens, broccoli, arugula, cress, sunflower, peas, mustard, and daikon.
- For gastronomy and superfoods: Amaranth, basil, cilantro, and shiso.
2. System Setup & Preparation
- Choose your system: Hydroponics, aeroponics, glass, germination tray, or tray.
- Prepare the necessary components: Nutrient solution, mats, filters, timers, LED lighting.
- Sterilize all work materials and maintain the highest hygiene standards – this reduces the risk of failure.
3. Prepare & Sow Seeds
- Use certified, germinable seeds – often organic quality for professional operations.
- Soak according to variety (e.g., growing radish microgreens: soak in water for 6-8 hours).
- Distribute evenly on the substrate, press lightly if necessary.
4. Promote Germination & Growth
- Keep the substrate/nutrient solution consistently moist (not wet!).
- Optimal temperature for most microgreens: 18–24 °C.
- Promote dark germination in the first days (cover with foil or lid), then full LED lighting.
- Regular monitoring for mold, failures, or nutrient deficiencies.
5. Harvest & Post-Processing
- Harvest usually after 6–14 days when the first “true” leaves appear.
- Cut close above the mat/net with clean knife or scissors.
- Remove residues, clean system, and start next culture.
Growing Microgreens in Glass – Possibilities and Advantages
Growing microgreens in glass is trending, especially for creative gastronomy concepts, startups, and private customers. Advantages include absolute freshness, hygiene, attractive presentation, and simple logistics. Microgreens in glass are also excellent as gifts or seasonal specialties for farm shops and organic stores. For professional operations, there are special germination glass systems that can be modularly integrated into larger production lines.
Growing Radish Microgreens – Particularly in Demand in the Professional Sector
Radish microgreens are among the most popular varieties for professionals and food startups: Fast-growing, sharp-spicy taste, high yields, and great demand in upscale cuisine. For professional cultivation, the most important success factors are:
- High-quality seeds, optimally suited for hydroponics.
- Short-term dark germination, then 12–14 hours LED lighting per day.
- Correct nutrient supply and pH control (pH 6.0–6.5).
- Hygienic conditions, regular filter and climate control.
Pro tip: Radish microgreens are ideal for continuous culture cycles – optimally combinable with superfoods, sprouts, and Co.
Growing Superfoods at Home – Microgreens, Sprouts & Co.
