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.
