Vegetables harvested at an immature growth stage:Sprouts: germinated seeds with emerging root Microgreens: 2-3
inches in height; 7-21 days(harvest stem, cotyledons, and emerging true leaves) Baby greens: 4-6 inches in height; 21-40 days Mature greens: >6 inches in height; 40-60 days Slide6

Nutrients assessment
Objective: to analyze the concentration of vitamins and carotenoids in 25 commercially available microgreens.Nutrients analyzed: 1) Ascorbic Acid (Vc) 2) Phylloquinone (VK1) 3) Tocopherols (VE)
4) Carotenoids (Provitamin A: β-Carotene, Lutein/
zeaxanthin, Violaxanthin.)Slide12
Top 5 microgreens
rich in carotenoids (provitamin A)No. 1 CilantroNo. 2 Red sorrelNo. 3 Garnet amaranthNo. 4 Red cabbage
No. 5 Pea tendrilSlide13
Simple steps to microgreens Fill
a shallow container with 1-1.5 in. of moist soilless growing mediaSow seeds thickly and evenly Water from bottomHarvest with scissors when 2-3 in. tallENJOY!Slide14
Try a variety of crops, containers, and locationsSlide15
What can I grow?
Fast and easy: arugula, kale, radish, broccoli, mustard, broccoli raab, bok choy, komatsuna and other Asian greens, cress, lettuces (fragile)More challenging: amaranth, beet, Swiss chard, cilantro, basil, pea and sunflower shoots Questionable:
spinach (hulls), cabbage (odor?)Slide16Slide17
Crops in same tray should have similar germination rates!Slide18
Commercial flats (trays) for growing larger quantities of microgreensSlide19
Repurposed shallow food container
(lid becomes saucer)Slide20
1 ½-in. depth of growing media
Tray-in-tray or container-in-container for bottom wateringSlide21
Salad tables can be used for for outdoor microgreen productionSlide22
5 quarts of growing media/tray
($1.50 - $4.00)Re-use mix after roots dry out (add to fresh mix)Slide23
Recommended plant spacing: 3/16 in. to 1/4-in.
Difficult to sow seeds evenly (no thinning necessary)20-row seeding flat contains around 1,000 plantsSlide24
Invasion of the “white
fuzzies”Slide25
Indoor growing: need light and heat
Window light may be insufficientLettuce, arugula, mustards, Asian greens will grow ok in low lightT-8 fluorescent lights can supplement or replace sunlight (keep tubes < 2 in. from plants)Slide26
20-row seeding flat produced larger plants and root systems than plain flatSlide27Slide28
Cut at “soil line” when greens are 2-3-in. tall
No re-growth Refrigerate for up to 10 days Slide29
