How to Start Growing Microgreens in a Simple Tray
Microgreens are edible seedlings harvested above the growing medium as their seed leaves develop and the first true leaves appear. Begin with one crop in a draining insert and solid catch tray. Use washable containers meant for food contact or edible growing.
Gather the Growing Supplies
- Untreated seeds sold specifically for edible microgreen production.
- A clean shallow growing tray with drainage and a separate solid catch tray.
- Fresh seed starting mix, prepared coconut coir, or a mat meant for growing edible crops.
- Drinking quality water, a small watering jug, and a clean misting bottle.
- A scale or measuring spoon, an exterior label, and clean sharp scissors for harvest.
- A light source, with a timer if using a grow light.
| Container arrangement | Useful for | Main care requirement |
|---|---|---|
| Draining tray and catch tray | A first crop or regular small harvests | Lift the insert and discard unabsorbed water. |
| Removable modules | Several crops with different schedules | Check each module rather than watering the whole grid automatically. |
| Glass or ceramic dish without holes | A small monitored display | Prefer a draining insert; direct planting needs careful moisture checks. |
| Shelves, wall holders, or a cart | Several batches in rotation | Provide good light and access to every level. |
Step 1. Choose a Crop and Record Its Growing Instructions
Choose seeds sold for edible microgreens, such as radish or broccoli. Keep crops with different germination and harvest times in separate modules. Record the variety and sowing date.
Use the seed supplier’s density and soaking directions. Scale quantities by growing area: a stated 20 g per 1,000 cm² becomes 5 g for 250 cm². The example explains the calculation; it is not a universal sowing rate.
Step 2. Prepare the Medium and Sow Evenly
Wash the tray and prepare fresh seed starting mix, coir or an edible crop growing mat. Moisten the medium, leave space below the rim and spread the measured seeds evenly without piles.
Press seeds into contact with the medium. Follow the crop’s germination cover directions, then uncover at the right stage for light and airflow.
Step 3. Set Up Light and a Bright Indoor Position
Choose a clean position with bright usable light, away from cooking heat, pet access and cleaning sprays. A grow light can supplement insufficient daylight; allow room to adjust its distance as seedlings develop.
Light every occupied tier and preserve gentle airflow. Avoid hot window ledges and cold glass contact. Crop instructions determine the right germination conditions.
Step 4. Water According to Moisture, Not the Calendar
Check moisture daily, including the tray’s center and edges. Mist gently during germination as needed. Once roots establish, bottom water a draining insert until the medium takes up moisture, then empty unabsorbed water.
Keep the medium moist without a persistent pool. Check wicks and reservoirs as well as the visible leaves; an automatic looking display still needs inspection.
Follow One Batch from Sowing to Harvest
Follow one batch from sowing to harvest. The Penn State Extension guide to growing microgreens at home photographs a tray day by day, with pea shoots ready on day nine in its example, and explains that species and conditions change the timing. Treat even a small decorative container as a crop that will be cut and restarted.
No household project cost or total labor time is published. For a first small daylight grown tray, allow 20 to 30 minutes to wash, fill and sow, brief daily moisture checks, and US$8 to 15 for seed, medium and reusable containers, with basic tools owned. Calendar growing time sits on top of that preparation; a grow light and rack need a separate budget. Label the sowing date and record the harvest day before expanding.
18 Microgreen Container Ideas for Indoor Spaces
1. Nest a Metal Growing Insert Inside a Solid Tray
A perforated metal insert nests above a solid tray. Choose openings that retain the medium or mat and leave its lifting edges accessible. For bottom watering, the medium needs direct contact with the water; a large air gap prevents transfer.
2. Arrange Removable Containers in a Modular Grid
Six individual pots fit inside one white catch tray, separating green and purple seedlings. Leave fingertip gaps around each rim. Equal pot sizes make replacement convenient while allowing each crop to follow its own watering and harvest schedule.
3. Frame a Small Batch With a Long Ceramic Dish
A long cream dish leaves a narrow growing strip on the counter. Fit a removable draining insert below its rim without wedging it tight. An intact food use glaze suits the outer dish; a hidden gravel layer does not create drainage.
4. Raise Small Growers on a Removable Rack
A rack raises small perforated growers above a broad base. Match any liner to the openings and leave the lower containers reachable. Water the raised pots separately unless a designed moisture transfer system connects them to the base.
5. Use a Clear Produce Container for a Short Trial
A clear produce box exposes the root layer as well as the shoots. Reuse only intact washable packaging, check for base drainage and provide a catch tray. Keep its hinged lid open after germination rather than enclosing emerged growth.
6. Step Three Growing Trays Toward the Light
Three stepped levels make each tray’s front edge reachable for checking moisture and cutting. Match the stand to the loaded trays, with removable waterproof catch bases. Harvest each batch at its crop’s seedling stage rather than waiting for it to match a taller neighboring planting; move larger companion herbs to their own growing pots.
7. Compare Flavors in a Divided Sampler Tray
Four independent inserts offer a small flavor sampler in a dark tray. Lift one section for watering or harvest without disturbing the rest. Label crops outside the growing area and compare them in a meal before choosing a larger batch.
8. Adapt a Nested Box for Controlled Wicking
An upper growing tray sits above a reservoir like base. A wicking setup needs a continuous wick or capillary mat meant for growing edible crops, with one end in the water and the other in contact with the growing medium. Test even moisture transfer before sowing and keep both layers removable for cleaning.
9. Show the Root Layer Through a Glass Dish
A square glass dish makes the root layer visible for observation. Prefer a fitted draining insert where possible. With direct planting, inspect the bottom for pooled water and keep the dish away from hot cookware and abrupt temperature changes.
10. Use a Small Cell Tray for Seed Comparisons
Small horizontal cells hold limited seed samples rather than a large harvest. Keep a matching crop diagram and check outer cells for drying. Compare one changed factor at a time, such as two densities of the same seed under equal conditions.
11. Pull a Growing Tray Forward Beneath a Light
A pull out bay brings the crop forward from beneath its light. Keep the growing tray and catch base independent of the wooden drawer. Size runners for the wet load and move the tray elsewhere for watering, clear of electrical connections.
12. Plant a Circular Tray Around an Open Center
A ring of seedlings leaves an open center around a small bowl. Calculate seed quantity over the planted ring, excluding the center. Leave scissors access along both edges and keep any serving bowl separate from growing runoff.
13. Pair a Clear Rectangular Grower With a Separate Base
A clear rigid grower sits on a pale base with a narrow footprint. Leave an accessible lifting edge. The base catches runoff only when the upper container drains; beneath a sealed dish, it protects furniture but cannot remove trapped water.
14. Give Each Wall Shelf Its Own Growing Light
Separate light bars serve successive wall shelves. Space each shelf for its tray, canopy and fixture clearance, with room to lift out a loaded crop. Keep watering removable and electrical connections outside the runoff route.
15. Keep a Bamboo Look Cover Separate From the Wet Tray
A rounded timber look cover softens the pale inner tray without becoming the growing container. Measure the curved interior and choose the removable draining insert and catch tray first. Lift those wet parts out for washing and leave the decorative cover dry.
16. Create Distinct Blocks of Seedling Color
Adjacent green and purple seedling inserts form distinct color blocks. Use crops with similar growing times or keep independent schedules within the pattern. Harvest each section when ready rather than delaying it to preserve the whole arrangement.
17. Organize Repeated Batches on a Growing Cart
A wheeled rack organizes repeated crops and their lights in one station. Lock casters during care and keep clean supplies protected below. Stagger sowing to match consumption before filling additional shelves, and manage cables before moving the rack.
18. Fit Interchangeable Growers Into a Countertop Housing
Four dark inserts share a rounded timber housing while retaining accessible rims. Select the growing and catch components first, then fit the cover around them. Keep the wood dry and remove each finished batch independently.
Harvest, Clean, and Prepare the Next Batch
Cut at the crop’s recommended stage with clean sharp scissors, above the medium. Leave roots and loose growing material behind. Plan fresh sowings as batches finish rather than expecting a permanent display.
Rinse the cut greens in drinking quality water just before eating. If storing the harvest, refrigerate it promptly in a clean container and avoid packing it wet; Penn State notes that washing can shorten its storage life. Discard a spoiled or uncertain crop rather than trying to rescue it by rinsing.
Remove spent roots and medium. Wash trays and clean reusable components according to their planned use, then dry before storage. Penn State’s home growing guide and microgreen production overview provide further crop and watering guidance.
