Microgreens Production Monitoring
Stage-aware climate recipes for 7-21 day microgreens cycles — germination → fluffing → harvest day — with per-rack dashboards and per-batch traceability records for the restaurant + retail buyers who actually ask.
Longer-cycle cultivation? See generic grow rooms. Mushroom-specific? See mushroom cultivation.
The Problem
7-21 day cycle leaves no margin for mistakes
Microgreens flip from germination to harvest in days. A bad afternoon during the fluff stage can drop yield 30% — and you don't get to replant fast enough to make up the lost crop.
Stack-shelf operations need per-shelf visibility
Commercial microgreens production uses vertical rack systems with 8–12 shelves per rack. Each shelf may host a different crop at a different stage. One sensor at the room level misses what each crop actually sees.
Light cycles + irrigation timing are manual
Most grow-room timers run on physical wall clocks. Switching cultivars or skipping a shift means hand-resetting them. Easy to forget; easy to drift.
Restaurant + retail buyers want traceability
Selling to restaurants and grocery means buyers occasionally ask for batch-level traceability. Paper logs from yesterday lose to digital records that auto-export.
How LoopString Solves It
Stage-aware climate recipes
Recipes that flip from germination (high RH, low light, 21°C) → fluffing (lower RH, light on, 18°C) → harvest day (lights, dehumidify) automatically. No paper sticky notes on the rack.
Multi-rack + per-shelf dashboard
Track sensors at the rack-level + per-shelf where you instrument it. Sparkline trends per cultivar lot. Schedule overlay so you can see when lights / irrigation actually fired.
Threshold alerts on the windows that matter
Configure alerts for fluffing-stage humidity drift + harvest-day temperature spikes. Anomaly detection catches misting-pump failure before the next watering cycle.
Per-batch traceability records
Per-lot PDF exports show the environmental conditions for each cultivar batch — useful for restaurant + retail buyers asking for traceability.
Built for these microgreens operators
Commercial microgreens producers
Multi-rack indoor producers selling to restaurants, grocery, and farmer markets — typical 50–500 trays/week.
Restaurant-supplied operators
Producers under-1000 trays/week supplying local chefs need per-batch records + reliability that beats their last paper-log incident.
Vertical-farm microgreens lines
Large vertical-farm operations running microgreens as one of multiple crops need per-shelf-row monitoring + multi-room dashboards.
School + research microgreens programs
Educational + research programs need clear per-cultivar logs for teaching + thesis defensibility.
Specialty cultivars + heirloom seed work
Niche cultivar producers (purple radish, sunflower, sango radish, fenugreek) often need per-cultivar timing different from the mainstream crops.
Wholesale + ghost-kitchen suppliers
Producers supplying ghost-kitchen aggregators need consistent batch-to-batch quality with audit-ready records.
