THROUGH THE Cultivator's LENS Product Evaluation

  • You are managing a propagation setup because standard trays keep buckling and cracking under heavy saturated media.
  • You are bottom-watering your seedlings because holding water at the base lets delicate mixes wick moisture evenly without surface disturbance.

  • The reinforced double-thick plastic construction resists the warping that happens when you move heavy saturated media.
  • The watertight base acts as a reliable reservoir for bottom-watering applications without risking leaks.
  • The raised floor channels elevate your pots so oxygen can reach the bottom of your root zones.

  • Growers using these as master trays say they stopped worrying about flats sagging under the weight of heavy insert pots.
  • Operators utilizing the watertight base for bottom-watering report healthier root zones without disturbing delicate surface seeds.

Grow1 Double Thick Propagation Tray No Drain Holes - 10" x 20"

For growers who demand industrial-grade durability, the Grow1 Double Thick Propagation Tray is the ultimate heavy-duty solution. While a standard propagation tray can become flimsy or brittle over time, this tray is engineered with a reinforced, double-thick plastic construction. It provides a rock-solid foundation for your clones and seedlings, resisting the warping, buckling, and cracking that often occurs when moving heavy, saturated media or full inserts.

This "No Holes" version serves as a completely watertight reservoir, making it the premier choice for bottom-watering applications. By holding water and nutrient solutions at the base, it allows your 50-cell seedling tray, rockwool, or seedling mix to wick up moisture evenly, reducing the risk of disturbing delicate surface-sown seeds. Its reinforced strength also makes it the perfect "master tray" to house multiple 3.5" square black injection molded pots or heavy insert flats without the tray sagging under the weight.

Like the rest of the Grow1 line, the base incorporates integrated raised channels to facilitate vital air circulation beneath your media. This ensures that even in a watertight environment, the root zone remains oxygenated. Proudly built to survive season after season of rigorous use, this double-thick tray is the last propagation flat you’ll ever need to buy.

FAQ

How much thicker is this compared to a standard tray? +

This tray is roughly twice as thick as standard nursery flats. This added density prevents the tray from "twisting" or bending when you lift it, making it much safer for transporting heavy pots or saturated seedling blocks.

Can I use this for microgreens? +

Absolutely. The "No Holes" design is perfect for microgreen growers who want to bottom-water to keep the foliage dry and prevent mold. Because it is double-thick, it can handle the weight of dense soil and water required for high-yield harvests, offering similar rigidity to the Grow1 Extreme Black Propagation Tray.

Is the plastic BPA-free and food-safe? +

Yes, Grow1 trays are made from high-quality horticultural plastic designed for food production, ensuring no harmful chemicals leach into your plants or water supply.

Will standard humidity domes fit on this double-thick tray? +

Yes. While the plastic is thicker, the exterior dimensions remain a standard 1020 footprint, ensuring a perfect seal with standard 2" and 7" propagation domes or a Super Sprouter 72-cell plug tray.

Why are there raised channels if there are no holes? +

The raised channels elevate your pots slightly off the flat bottom of the tray. This prevents your plants from sitting in a complete anaerobic "puddle" and allows some air to reach the bottom drainage holes of your pots or inserts.
