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.<\/p>\n<ul>\n<li><strong>Location &amp; Space:<\/strong> Space requirements are minimal, especially with vertical farming. Large quantities of microgreens can be produced even in just a few square meters.<\/li>\n<li><strong>System Selection:<\/strong> Hydroponics, aeroponics, germination trays, multi-level shelving, or glass culture \u2013 the choice depends on product range, space, budget, and target market.<\/li>\n<li><strong>Lighting:<\/strong> LEDs with optimal light spectrum are crucial for fast, compact growth and high vital substances.<\/li>\n<li><strong>Nutrient Solution:<\/strong> The quality and composition of the nutrient solution is the key to color, taste, and nutrient density.<\/li>\n<li><strong>Filter and Climate Technology:<\/strong> Professional air filters and climate control ensure hygiene, stable conditions, and reduce the risk of fungal infestation and failures.<\/li>\n<\/ul>\n<p>Our experts advise you in planning and optimizing your professional microgreens facility \u2013 from the first germination test to scalable high-tech systems.<\/p>\n<h2>Growing Microgreens Without Soil \u2013 Methods, Systems &amp; Comparison<\/h2>\n<p>Below you&#8217;ll find an overview of proven methods for <strong>growing microgreens without soil<\/strong> \u2013 from small DIY approaches to commercial systems:<\/p>\n<ul>\n<li><strong>Hydroponics:<\/strong> 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.<\/li>\n<li><strong>Aeroponics:<\/strong> Here the roots &#8220;hang&#8221; freely in the air and are regularly misted with nutrient fog \u2013 this increases oxygen uptake and growth.<\/li>\n<li><strong>Germination Jars &amp; Glass Culture:<\/strong> Particularly popular with food startups and urban gardeners. Sprouts, microgreens &amp; Co. are grown directly in glass, usually on a sieve.<\/li>\n<li><strong>DIY Germination Trays &amp; Trays:<\/strong> Practical for small quantities or test runs. Place sprouting mat on a tray, moisten regularly, and harvest after a few days.<\/li>\n<\/ul>\n<p>Anyone who wants to <strong>grow microgreens<\/strong> or <strong>grow microgreens themselves<\/strong> will find the right solution for every scale and requirement with these methods.<\/p>\n<h2>Microgreens Growing Instructions \u2013 Step by Step to Success<\/h2>\n<h3>1. Selection of Microgreens Varieties<\/h3>\n<ul>\n<li>Popular varieties for soilless cultivation: Radish microgreens, broccoli, arugula, cress, sunflower, peas, mustard, and daikon.<\/li>\n<li>For gastronomy and superfoods: Amaranth, basil, cilantro, and shiso.<\/li>\n<\/ul>\n<h3>2. System Setup &amp; Preparation<\/h3>\n<ul>\n<li>Choose your system: Hydroponics, aeroponics, glass, germination tray, or tray.<\/li>\n<li>Prepare the necessary components: Nutrient solution, mats, filters, timers, LED lighting.<\/li>\n<li>Sterilize all work materials and maintain the highest hygiene standards \u2013 this reduces the risk of failure.<\/li>\n<\/ul>\n<h3>3. Prepare &amp; Sow Seeds<\/h3>\n<ul>\n<li>Use certified, germinable seeds \u2013 often organic quality for professional operations.<\/li>\n<li>Soak according to variety (e.g., growing radish microgreens: soak in water for 6-8 hours).<\/li>\n<li>Distribute evenly on the substrate, press lightly if necessary.<\/li>\n<\/ul>\n<h3>4. Promote Germination &amp; Growth<\/h3>\n<ul>\n<li>Keep the substrate\/nutrient solution consistently moist (not wet!).<\/li>\n<li>Optimal temperature for most microgreens: 18\u201324 \u00b0C.<\/li>\n<li>Promote dark germination in the first days (cover with foil or lid), then full LED lighting.<\/li>\n<li>Regular monitoring for mold, failures, or nutrient deficiencies.<\/li>\n<\/ul>\n<h3>5. Harvest &amp; Post-Processing<\/h3>\n<ul>\n<li>Harvest usually after 6\u201314 days when the first &#8220;true&#8221; leaves appear.<\/li>\n<li>Cut close above the mat\/net with clean knife or scissors.<\/li>\n<li>Remove residues, clean system, and start next culture.<\/li>\n<\/ul>\n<div class=\"ca_cta\" style=\"padding: 50px; background: #151821; border-radius: 18px; box-shadow: 0 6px 32px 0 rgba(0,0,0,0.16); margin-top: 3rem; margin-bottom: 3rem;\"><div class=\"ca_cta_wrapper\" style=\"display: flex; flex-direction: row; align-items: center; gap: 32px;\"><div class=\"ca_cta_logo\" style=\"flex: 0 0 auto; max-width: 250px;\"><img decoding=\"async\" src=\"https:\/\/carbonactive.com\/wp-content\/uploads\/2025\/02\/CA-Logo25-White-SFS.svg\" alt=\"CarbonActive Logo\" style=\"max-width: 250px; width: 100%;\"><\/div><div class=\"ca_cta_content\" style=\"flex: 1;\"><div style=\"font-size: 28px; font-weight: 700; color: #fff; line-height: 1.2; font-family: DM Sans, Arial, sans-serif; margin-bottom: 8px;\">Training &amp; Workshops for Microgreens Cultivation<\/div><div style=\"font-size: 17px; color:#fff; margin-bottom: 28px; font-family: DM Sans, Arial, sans-serif;\">Book training for your team now \u2013 from cultivation techniques to hygiene and marketing.<\/div><div style=\"display: flex; gap: 18px; flex-wrap: wrap;\"><a href=\"https:\/\/meetings-eu1.hubspot.com\/lminks?uuid=9ab3097b-8de4-4ff5-b2fb-dfac2e6b564d\" class=\"ca_btn_primary\" target=\"_blank\" rel=\"noopener\">Book consultation<\/a><\/div><\/div><\/div><\/div>\n<h2>Growing Microgreens in Glass \u2013 Possibilities and Advantages<\/h2>\n<p><strong>Growing microgreens in glass<\/strong> is trending, especially for creative gastronomy concepts, startups, and private customers.
