The right tray for starting, growing, and harvesting microgreens, whether you grow a tray at a time or run a microgreens business.
These shallow 1020 germination trays are the same style used on commercial microgreen farms, and they work just as well for home growers. The low profile lets you cut your greens right at the base for cleaner harvests, higher yields, and beautiful presentation on the plate or at market.
Built to the standard 1020 format, these measure 21 1/8″ x 10 3/4″ across the top edges and stand just 1 1/4″ deep, so they drop straight into any setup where your current 1020 trays already fit.
Why drainage holes are a must, not a maybe
Trays with drainage holes are essential for drainage and preventing mold. Excess water is the number one cause of failed trays. When water pools around the roots, you get damping off, root rot, and fungal growth that can wipe out a crop overnight.
The holes solve this two ways. They let excess water escape and drain after seeding, misting, or top watering, and, more importantly, they let you water from the bottom once sprouts are growing, which keeps the leaves dry and dramatically cuts your mold risk.
How to grow microgreens in these trays
Microgreens are one of the fastest, most forgiving crops you can grow. Most are ready in 7 to 14 days from seed. Here is the full process professional growers rely on, using a simple stack of three trays.
1. Set up your trays. Nest this tray with drainage holes inside a solid tray with no drainage holes. Early on, you water from the top and the solid bottom tray simply catches any runoff. Later, once the greens are growing, that same tray holds the water for bottom watering. The matching base is our 1020 Microgreen Trays with No Drainage Holes, double-thick and rigid so it holds water without flexing.
2. Add your medium and seed. Fill the tray with drainage holes with about an inch of growing media. Our Seed Starting Mix is a great fit, or you can use coco coir or a hemp mat. Level it, mist lightly so the seeds do not bounce, then scatter your microgreen seeds evenly across the whole surface. Seed densely, but avoid clumps and thick pa
