Additional Information

Trays for Our Deep Root Seedstarting System

  • Long-lasting, reusable seedstarting trays
  • Deep cells encourage large, healthy root systems
  • Heavy, dishwasher-safe plastic is easy to clean for use year after year
  • Sized for use with the reservoir base of our Deep-Root Seedstarting System

The secret to growing stocky, vigorous seedlings that thrive when transplanted outdoors is a strong root mass. The tapered cells of these trays are 50% deeper than similar seed trays which means more room for root mass. This unbreakable tray is designed for using on the reservoir base of our Deep-Root Seedstarting System.

      I used these trays to start my cabbages, broccoli, Brussels, and peppers this week. The tray fits nicely on my grow rack. The trays are sturdy and easy to move when rotating trays under grow lights.

        Large cell size is great. Hoping this will help to to avoid need for potting-up prior to transplant.

            Comments about : 15-Cell Tray, Black:

            I use this seed starter to move early starts into, but I am becoming more enamored with just starting plants, particularly things that get big fast like tomatoes, cucumbers, sunflowers, zinnias in these from the get go.
            It cleans easily and I reuse it multiple times over the summer. Just used it late summer to pull out some small plants like perennial begonias and Black eyed Susan's to establish some roots before transplanting elsewhere and they did beautifully! Much better than my direct transplants.
            Highly recommend these. I keep buying more!!

              Comments about : 15-Cell Tray, Black:

              I started perennial wildflower seeds in about 15 different kinds of starter cells last fall. This was the best. The plants developed a good healthy root system, because the cell is big enough. The hole in the bottom is big, so I can put my finger in and push the whole plant out at once. It comes out in one piece, without breaking up, so the root suffers minimal disturbance, and the plant has a great chance of transplanting successfully. After seeing how great my seedlings came out, I order four more of these and will use them for my most valuable plantings this year.

                  I wish they were still available. If your other systems could survive a dishwasher, you'd advertise it.

                  Excellent Deep Tray! It is very sturdy!
                  It doesn't fit a standard 10"x20" seed tray.

                    I will be planting my tomato seeds in it, and am looking forward to better, healthier plants, thanks to the additional depth. I also think they will be much sturdier than others I have tried, and should last for quite some time.
