Learn how to set up and use Microgreens Grow Mats for soil-free growing, with watering tips and a step-by-step routine for healthy, even germination.
Quick answer
Place one Microgreens Grow Mat in your EZ Microgreens Planter, moisten it evenly, scatter seeds across the surface, and keep the mat consistently damp—not soaked—until harvest. The 40-pack gives you enough mats to fill both planters 10 times, so you can stagger plantings.
Why use a grow mat instead of soil
A grow mat replaces loose potting mix with a clean, compostable bamboo-fiber surface. That means no soil dust, no fungus gnats, and no mess on your countertop. The mat holds moisture at the seed level, which helps germination stay even across the tray. For anyone growing microgreens in a kitchen or small apartment, this is a practical alternative to soil-based trays.
Watering: the most common failure point
Mats dry out faster than a deep soil tray, especially in dry indoor air. Check moisture daily by pressing a finger gently on the mat; it should feel damp but not drip when you tilt the planter. Bottom-watering—pouring water into the planter’s reservoir rather than over the top—keeps seeds from being displaced and reduces mold risk. If you top-water, use a spray bottle and mist lightly.
When a mat is not the right choice
If you want to grow microgreens with a thick root mat for easy lifting, or you are growing varieties that need a deeper root zone, a soil-based tray may suit you better. Grow mats are best for small-seeded crops like broccoli, kale, radish, and mustard. Also note that the 40-pack is designed for the EZ Microgreens Planter; if you use a different container, check that the mat fits flat without folding.
Step-by-step: using Microgreens Grow Mats
- Fit the mat to your planter: Place one mat flat in the EZ Microgreens Planter tray. If it overlaps the edges, trim with clean scissors so water can wick evenly. Common mistake: folding or doubling the mat, which creates dry pockets. A flat, single-layer fit is the checkpoint—no wrinkles or overlaps.
- Moisten the mat before seeding: Pour water into the planter’s reservoir or mist the mat until it is evenly damp but not pooling. Let it sit for a few minutes so moisture wicks across the whole surface. Mistake: seeding a dry mat, which wicks moisture away from seeds. The mat should feel like a wrung-out sponge, not a wet paper towel.
- Sow seeds evenly: Scatter seeds across the mat, aiming for about 1/8 inch spacing for small varieties. Do not bury them—most microgreen seeds need light to germinate. Mist lightly after sowing to settle them. Mistake: dumping seeds in a clump, which causes overcrowding and mold. Even spacing now means less thinning and better airflow later.
- Maintain moisture daily: Check the mat every morning. If it feels dry, add water to the reservoir or mist the surface. Keep the planter in a bright spot but out of direct harsh sun until sprouts appear. Mistake: soaking the mat, which invites damping-off. Consistent dampness—not sogginess—is the daily goal.
- Harvest and replace: When greens are 2–3 inches tall, snip above the mat with clean scissors. Compost the used mat and start a new one. With 40 mats, you can replant immediately. Mistake: trying to reuse a mat, which can harbor pathogens and falls apart. One mat per crop—compost after harvest, then start fresh.
