Vom einfachen Tray bis zum Kreislaufsystem

Growing Methods for Microgreens

There are four fundamental methods for growing microgreens. They range from simple trays lined with natural fibres to fully controlled recirculating and multi-tier systems. The most suitable method depends on the crop, production volume, available space, hygiene requirements, investment budget and desired degree of automation.

Substrate-based crops are robust and well suited to beginners. Pure hydroponics provides particularly precise control over water and nutrients. Aquaponic integration combines plant production with a fish-rearing system and requires careful biological balance. Vertical farming describes the spatial arrangement of production across several tiers and can be combined with various irrigation methods.

Substrate-basedTrays with hemp, jute, coir or celluloseLow to intermediateReliable germination and an accessible starting pointControl moisture and consumable materials
HydroponicsDWC, adapted NFT or aeroponicsIntermediate to highPrecise management of water and nutrientsSafeguard equipment, light exclusion and cleaning

Vertical farmingStacked trays under controlled LED lightingIntermediate to highExcellent use of limited floor spaceManage energy, climate and uniformity on every tier

This classification is intended as a guide. Actual complexity depends on system size, automation, crop and hygiene plan.
