Sunflower midpoint seed = 80g/tray. Yield midpoint = 10 oz/tray. Monthly yield = 10 × 4 trays × 3 cycles = 120 oz. Revenue = 120 × $2.50 = $300. Seed = 80g × 4 × 3 = 960g = 2.12 lbs × $3.50/lb = $7.39.

Radish midpoint seed = 30g/tray. Yield midpoint = 8 oz/tray. Monthly yield = 8 × 10 trays × 4 cycles = 320 oz. Revenue = 320 × $3.00 = $960. Seed = 30g × 10 × 4 = 1,200g = 2.65 lbs × $8.00/lb = $21.16.

Broccoli midpoint seed = 12.5g/tray. Yield midpoint = 5 oz/tray. Monthly yield = 5 × 6 trays × 3 cycles = 90 oz. Revenue = 90 × $3.50 = $315. Seed = 12.5g × 6 × 3 = 225g = 0.496 lbs × $18/lb = $8.93.

Frequently Asked Questions

Q

How many ounces of microgreens does one tray produce?

A standard 10×20″ tray yields 3–16 oz depending on the variety. High-yield varieties like wheatgrass produce 12–16 oz per tray, while lighter greens like basil or amaranth yield 3–5 oz. Seed density, light quality, and grow medium all affect final harvest weight.

  • Wheatgrass: 12–16 oz per standard tray — highest yield variety
  • Sunflower: 8–12 oz per tray, popular at farmers markets ($2–$4/oz)
  • Pea shoots: 6–10 oz, fast turnaround of 8–12 days
  • Basil and amaranth: 3–5 oz, lower yield but higher selling price ($3–$5/oz)
  • Mixed blends: 5–8 oz per tray, good for subscription boxes

Radish6–105–825–35
Broccoli4–65–710–15
Q

How much seed do I need per microgreen tray?

Seed density varies widely by variety. A standard 10×20″ tray needs 5–130 grams of seed depending on the crop. Large seeds like pea shoots require 100–130g, while tiny seeds like amaranth need only 5–8g. Overseeding reduces yield per seed but can increase total weight.

  • Pea shoots: 100–130g per tray — heaviest seed requirement
  • Wheatgrass: 80–100g per tray, buy in bulk at $2–$3/lb
  • Sunflower: 70–90g per tray, pre-soak 8–12 hours for faster germination
  • Broccoli: 10–15g per tray — tiny seed goes a long way
  • Amaranth: 5–8g per tray, the most seed-efficient variety
Q

How profitable is growing microgreens?

Microgreens sell for $2–$4/oz at farmers markets and $25–$50/lb wholesale. A small operation with 10 trays and 3 cycles per month can gross $600–$1,200/month. Seed costs are typically 10–20% of revenue, making microgreens one of the highest-margin crops per square foot.

  • Farmers market price: $2–$4/oz retail, $25–$50/lb wholesale
  • Seed cost is typically 10–20% of gross revenue
  • 10 trays × 3 cycles × 10 oz avg = 300 oz/month ($600–$1,200)
  • Restaurant sales: $15–$30 per delivery, 2–3 deliveries per week per account
  • Subscription boxes: $20–$40/box for a mixed variety weekly delivery

Q

How long does it take to grow microgreens?

Most microgreens are ready to harvest in 5–14 days. Fast growers like radish and arugula take 5–8 days. Slower varieties like cilantro need 10–14 days. The growth cycle includes 2–3 days of blackout (germination), then 3–11 days under grow lights before harvest.

  • Radish and arugula: 5–8 days — fastest turnaround varieties
  • Sunflower and pea shoots: 8–12 days, requires soaking seeds first
  • Cilantro: 10–14 days, slowest common variety but high demand
  • Blackout phase: 2–3 days under dome/cover for germination
  • Stagger plantings every 2–3 days for continuous harvest supply
Q

What is the best microgreen variety for beginners?

Radish microgreens are the best starter crop — they germinate fast (5–8 days), tolerate temperature swings, and yield 6–10 oz per tray. Sunflower is another beginner-friendly option with high yield and easy handling. Avoid cilantro and basil until you master humidity and airflow control.

  • Radish: fastest grow time (5–8 days), very forgiving of mistakes
  • Sunflower: high yield (8–12 oz), large seeds are easy to handle
  • Pea shoots: simple to grow, popular flavor, 8–12 day cycle
  • Broccoli: low seed cost per tray (10–15g), consistent results
  • Avoid cilantro and basil as first crops — they need precise humidity control
