Used twice, then broke
Used twice. The second time while popping the plants out, the silicone cracked on several cells. I was told it has a 90 day warranty.
    I love the size of these trays. So much easier to handle than the 1020 flimsy plastic ones when they are full. For all those that have issues with the lack of humidity domes....I am using the domes from my 1020 trays. Two of these silicone trays fit perfectly under these clear domes. Alternately, these can be placed inside the black bottoms of the 1020 trays, then the bottoms from these can be used as the top humidity domes. Since I only use the domes until everything in the tray germinates, this method works perfectly for me.

      The ONLY reason this does not get 5 stars is because I WISH it had a clear lid/cover. Other that that I LOVE these trays. I dishwasher mine every year to sanitize them & reuse. I would be willing to buys covers if they ever make them! PLEASE!!

        Best start ever!
        The seedlings are strong and healthy with a wonderful root ball. The trays are sturdy - mine have been going in and outside this week to harden off. I used some old domes when I first planted, but a little sheet of plastic wrap would have worked also. Not a big deal - that only matters for a few days. These are easy to water and easy to pop out! I'm ordering more.

          Best seed starter tray ever.
          I had a similar setup with folding soil containers that watered from the bottom, but the folding part is thin crnkly plastic that is on its last legs. Used this new tray for broccoli this winter. Just transplanted outside and the root ball was so thick, not one grain of soil fell from any of the 32 plants. I highly recommend this tray. I thew away my old stuff that required foam pyramids to start seeds and transplanting to peat pots. This requires much less time and over-underwatering just doesn’t happen. These things are sturdy and will most likely outlast this gardener. Owe, I left out the price. They practically give them away.

            Bought more for 2021
            Bought a Pop-Out tray last spring and loved the convenience. Went back for more and they were sold out. Works as advertised. The flexible cells slide the seedlings out and then flex back into form. The raised rim on the edge of the tray keeps the soil and water contained inside the tray. Would like more size options.

              Great size & shape, but silicone doesn’t last
              I bought my tray 2 years ago. It’s a great design and size and is easy to use. The silicone makes it easy to release the plant without damaging the root. The only downside is that the silicone gets brittle and breaks by year 2. I still have the base tray which I can use with standard seed pots but it’s a shame I can’t buy a replacement top through the site.
                Excellent material! The bottoms are easy to push out while keeping your starts intact with soil
                I just bought this. I’m going to grow watercress in them. I’m making liners for inside each compartment out of fine mesh fabric netting so my vermiculite and peat moss won’t fall through. I wonder if you make a lid/ cover for this tray. If so I’d like to buy two.

                  Great feature
                  I was very disappointed to find after purchasing 10 of these beauties there is NO humidity dome. Will not purchase again until the KIT comes with a DOME!!!
                    nice but disappointing
                    As soon as I picked one up I was sold, these are very well made stronger and better made than any I've ever seen but I should have paid better attention to them ,I assumed they were like all the other seed starter kits and came with a humidity dome ....sadly they don't I didn't find it out til I got them home and as well made as they are I will be returning them and going with a seed starter kit with humidity domes
