Equipment Required To Grow Microgreens
Radish Microgreen Seeding Density & Germination
Crop Cycle: 4 to 9 days from seed to harvest.
Sanitize Radish Seed: No
Soak Radish Seed: No
Radish Microgreen Seeding Density Per 1020 Tray: 50 – 80g (1.75 – 2.85 oz)
Step #1 Have your 1020 tray with holes inside 1020 tray without holes, bottom watering is required to reduce mold issues and increase shelf life.
Step #2 Spread seed over pre-moistened tray using multiple passes to get even distribution while spreading seeds over the top of the soil while broadcasting.
Step #3 Once radish seeds are sprinkled evenly over the soil, mist the seeds prior to stacking the trays so the dry radish seed is now wet (this greatly increases germination rates).
Step #4 Stack trays 1 to 3 high with empty 1020 tray on top (no holes) and 15 lb weight for 2 to 4 days.
After 2 to 4 days radish microgreens will be sticking out along the side of the trays, unstack when radish is 1″ tall, top or bottom water heavily the day you uncover and place under the grow lights.
How To Grow Radish Microgreens
Step #1 Watering: Top or bottom water the radish the day you unstack from the germination phase.
Then bottom water the radish throughout the rest of the growing cycle to keep the foliage dry. It is pretty much impossible to spin dry wet radish foliage.
Packaging wet radish foliage into a clam shell or plastic bag will greatly decrease your shelf life.
Step #2 Growing: Keep under lights for 2 to 5 days. It is important to ensure good airflow & low humidity in your grow room to prevent mold issues.
Step #3 Possible Problems: During the growth phase grow rooms or areas with poor airflow (not enough fans), hot/humid conditions. or overwatering can experience mold.
If you discover your radish or a portion of your radish have fallen down and are laying flat on the soil, they have been under-watered. Bottom water your tray and within 4 to 6 hours your radish will be standing back up again.
How & When To Harvest Radish Microgreens
Average Yield: 340 – 500 g (12 – 18 oz) per 1020 tray
Step #1 Harvest Tools: Sharp knife (Radish microgreens should be harvested once they are 1 to 2 inches tall.)
Step #2 Harvest Process: Do not water for at least 12 hours prior to harvest to ensure greens are dry.
Cut and place directly into the packaging. If greens are wet they must be dried prior to packaging to improve shelf life.
Step #3 Packaging: Package into clamshells or bags as dry as possible because when packaged dry radish microgreens can easily last up to 7 to 9 days when refrigerated.
Absorbent pads may be used to remove moisture.

- Magnesium: Improve the body’s biochemical reactions and has anti-inflammatory benefits.
- Phosphorus: Helps build strong teeth, manage body energy stores, and decrease muscle pain after exercise.
- Potassium: An increased potassium intake may reduce the risk of overall mortality by 20 percent by decreasing the risk of stroke, lower blood pressure, and protecting against loss of muscle mass.
- Zinc: Helps your immune system, metabolism function, wound healing, and your sense of taste and smell.
Radish Microgreens Grow Tips Summary
#1 Grow Tip: Easy microgreen to grow and harvest with consistent yields.
#2 Grow Tip: Wet your soil bed, spread seed, and be sure to mist your seeds prior to stacking. The misting process will greatly improve germinations.
#3 Grow Tip: Bottom water to reduce potential of mold and rotten smell.
#4 Grow Tip: Important not to water 12 hours prior to harvest. It is very hard to get foliage dry if recently watered prior to harvest. Packaging wet will quickly decrease shelf life!
#5 Grow Tip: Amazingly nutritious 40 times more nutritious than mature radishes.
I hope these tips above helped you improve your yields!
