Who This Is For

  • You are choosing white trays because they reflect light back to the lower canopy rather than absorbing it like black.
  • You are investing in heavy-duty flats because standard trays buckle and spill when you lift them for transport.

What We Found

  • The white plastic is actually useful for lighting as it reflects light back up to the underside of the leaves
  • We noticed these do not shatter even when you stack a heavy pile of them together for off-season storage
  • The interior ridges are high enough to keep inserts out of the water even if you slightly overfill the base

What Users Say

  • Consistently bottom-watering the crop becomes possible once you have a tray that holds water without leaking
  • Spotting algae or debris in the water is much easier against the white plastic than it ever was in black trays

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

The Grow1 White 10x20" Propagation Tray is a staple for indoor gardening, providing a clean and professional foundation for your cloning and seed-starting needs. Proudly manufactured in the USA, this tray is constructed from a premium, pliable plastic that is far more durable than standard, brittle nursery flats. The bright white finish is not only aesthetic but also helps reflect light toward your lower canopy, maximizing every watt in your grow room.

This "No Drain" version is designed to act as a reservoir, making it the perfect choice for bottom-watering seedlings or catching excess runoff from rockwool cubes, seedling inserts, or starter plugs. By keeping the water contained, it protects your shelves, flood tables, and floors from moisture damage. The base of the tray features integrated raised channels that allow for vital air circulation beneath your pots or insert trays, preventing the stagnant conditions that lead to root rot.

Built to last season after season, this crack-resistant tray follows the industry-standard 10" x 20" footprint. It is perfectly compatible with standard humidity domes and all Grow1 50-cell, 72-cell, and 102-cell inserts. Whether you are managing a high-volume nursery or a home hobby tent, these USA-made trays offer the reliability you need for successful propagation.

FAQ

When should I use a tray without drain holes? +

Trays without holes are ideal for bottom-watering (wicking), as they allow seedlings to drink from the base. They are also essential for indoor use to catch runoff from your insert trays, preventing water from damaging your floors or grow tents. If you require drainage, we also offer the standard propagation tray with drain holes.

What is the benefit of the white color? +

White trays reflect light better than black trays. This reflection helps increase the light intensity reaching the underside of the leaves and the lower stems, which can lead to slightly faster growth and more vigorous starts.

Are these trays heavy-duty enough to carry? +

Yes. These trays are made from a premium pliable plastic that is much sturdier than standard "one-time-use" nursery flats. For maximum strength and light reflection, you may also consider the Extreme White Propagation Tray.

Will standard humidity domes fit? +

Yes, this tray follows the industry-standard 1020 (10" x 20") footprint and is compatible with almost all 7" and 2" humidity domes on the market.

How do I clean and sanitize these for reuse? +

Thanks to the crack-resistant plastic, you can scrub these with warm water and soap, followed by a sanitizing dip in a diluted bleach or hydrogen peroxide solution between growing cycles.
