Who This Is For

  • You are moving to bottom-watering because top-down misting keeps washing seeds out of their pockets.
  • You are using these as catch trays because runoff from your insert flats is creating a mess on your benches.

What We Found

  • The pliable plastic is the big win here because it stays flexible instead of getting brittle after a few cycles.
  • We suggest these for bottom-feeding since the watertight design acts as a perfect reservoir for nutrients.

What Users Say

  • Growers who move trays frequently say the flexible material prevents the corners from cracking under pressure.
  • Users who bottom-water say their crop develops more robust root systems by seeking moisture at the base.

Grow1 Standard Propagation Tray No Drain Holes - 10" x 20"

The Grow1 Standard 10x20" Propagation Tray is the industry-standard foundation for successful seed starting and cloning. Engineered for versatility, this tray provides a reliable environment for propagating with rockwool cubes, seedling mix, or 50-cell seedling inserts. Unlike flimsy, single-use alternatives, Grow1 trays are manufactured from a pliable, crack-resistant plastic designed to withstand the rigors of a busy grow room season after season.

This "No Holes" version is a completely watertight reservoir, making it the essential choice for growers who prefer the bottom-watering method. By holding water and nutrient solutions at the base, it allows your media to wick up moisture as needed, ensuring consistent hydration without disturbing delicate surface seeds or stems. It also serves as the perfect catch-tray for propagation trays with holes, keeping your grow area clean and dry.

To enhance plant health, the base of the tray features integrated raised channels. These ridges provide structural support and elevate your pots or insert trays, allowing for vital air circulation underneath the root zone. With a standard 10" x 20" footprint, this tray is perfectly compatible with all Grow1 humidity domes, heat mats, and various nursery inserts.

FAQ

What is the benefit of a propagation tray without drain holes? +

Trays without holes are ideal for bottom-watering seedlings, as they act as a reservoir to hold water and nutrients. They are also used as "leak-proof" base trays to sit under 72-cell seedling inserts that do have holes, preventing water from spilling onto your shelves or floor.

Are Grow1 trays stronger than standard nursery trays? +

Yes. These trays are made from a pliable, crack-resistant plastic blend. While standard trays are often brittle and break after one use, Grow1 trays are designed to be flexible and durable enough for multiple seasons.

Can I use this tray with a heat mat? +

Absolutely. This tray is designed to sit directly on standard 10x20 heat mats. The plastic is thick enough to withstand the heat while conducting it evenly to your starting media.

Will standard humidity domes fit this tray? +

Yes, this follows the industry-standard 1020 footprint. It is compatible with all Grow1 domes (2" or 7" tall) and most other standard domes on the market.

What are the raised channels at the bottom for? +

The channels serve two purposes: they add structural strength to the tray and they lift your pots or insert trays slightly off the floor. This elevation allows air to circulate underneath, which helps prevent root rot and keeps the root zone healthy.
