5 PCS Reusable Seed Starter Tray, 60 Cells Seed Starter Kit with Flexible Pop-Out Cells, Seedling Starter Trays for Seed Starter, Indoor Greenhouse Seeding Planting Growing

I did a lot of product research in setting up my seedling start set-up and happily decided on these. They are good products, sturdy plastic structure and silicone bottoms with cute smiley faces for drains - which my kids loved. Functionally, they are doing their job with plenty of starts growing well. I still have them with bottom pans, but they would easily work in cross-hatch open trays when I'm not bottom watering. I also bought the new Burpee silicone trays and I will say Burpee's silicone is thicker, but these will still work fine, just be a little gentle when using tools at the bottom.Amazon has several of these style trays and I bought 4 types. Three are these silicone style - and all three are exactly the same in quality/product (they even stack together), it just color that's different. The fourth style is a transparent hard plastic tray with the same dimensions, but no silicone bottom. It came in a kit I bought. All four starter styles are interchangeable with the kits that have these approx. 5"x7" trays. I like these silicone ones better than the clear hard plastic as they seem to be able to remove the seedling better and they have better drainage than the clear plastic ones which only have one 1/4" hole. (I'm actually not sure how I'm going to remove the ones from the clear plastic as unless they grow thick root systems as the plastic is too hard to push out without bending up the tray.)I have two set-ups for these silicone starters - one is a 4 tray, 96 cell kit and the other is an individual tray, 12 cell kit with domes, bottom trays and some with lights and heating mats. (The individual kits and the 4 tray kits are found on Amazon). Both are great. I use these starter trays with individual 12-cell bottom tray/dome for germination and then after sprouting move the starter tray to the 96 cell/4 starter tray for growing and bottom watering. This allows me to control plants per individual 12 cell tray instead of the larger trays, giving my plants better optimal germination conditions and me small enough crop sizes to not have loads of extra plants. In additional to the interchangeability, I also like that these are reuseable and super easy to clean.That said, it's important to note that these are made for the approx. 10"x14" trays and do not fit evenly in the greenhouse standard 10x20 tray. For my rack size, the 10"x14" trays fit two to a rack rather than one 10x20, increasing my useable space (although the heating mat is still only 10x20 and doesn't catch every cell, but it's still working great for me). If you're looking for the 10x20 standards for larger scale growing you can use the Burpee silicone trays as they fit two to a 10x20 tray, but they don't have domes (at least not yet from what I could find). For me and my household sized needs, these trays are better suited and work great. Happy Gardening!

I've been using these for a couple of years now, and have been very satisfied. I only use the individual pots; the connected planting cells (not sure what to call them) are too shallow for root development. I dunno, maybe those work for sprouts? But the main part of the set—the domes, the trays, and the little clear pots—have been great. They have improved my seed starting and help keep bugs away from my seedlings while ensuring they get enough humidity (but not too much).I love the clear pots; they ARE a little flimsy, but I have reused mine several times and they're still going strong. Being able to visually asses root development is incredibly helpful. No more guessing if your baby plants are really ready for potting up!The one caveat I have to potential buyers is that these are not very UV-resistant; if you leave the domes and trays outside for a season, the plastic will crack. But for starting seeds indoors, even under grow lights, they are great.

The silicone makes it easier to remove seedings and push the entire root ball out. It will hold up to use but the drainage hole in the bottom is quite large so when you try to fill it with dry potting soil, it runs out. I cut small squares of newspaper to place in the bottom to hold soil in, or you can wet the soil first, then put it in the bottom. It may drip out with watering later, but I haven't tried this way, so don't know for sure. All other silicone seeding trays seem to have the same size drainage hole, so doesn't seem like you can escape this problem.

I didn't know quite what to expect, but for the price I was well pleased. I don't know what it's longevity will be but the pieces all fit together snugly and seem of decent quality. Can't beat the price. And the tags and extra tools are handy. Each of the 7 starter trays has room for 12 seedlings. The fitted lids with adjustable air is nice for humidity control and the transparency of the "individual" pots is great for checking for root growth. The size of each pot is very good and eliminates the need for continuous up potting.

I loved that these were small for my indoor seedlings but also could be used year after year! The silicone sleeve also makes getting seedlings out so easy!

Just received the Cell starting trays and the Cell size was totally not what was advertised. They’re supposed to be about 2 inches deep and they’re a little bit more than one inch. Not much root for root development.. The trays and domes themselves are very well-made in a thick material. Also they are not individual cells which was the whole reason that I bought this set. Not worth the hassle to return this item. I will use the humidity domes on other sets. I already have.

I love these compared to the hard plastic trays I usually use. Perfect size for starting seeds. I used these to start my flowers and vegetable seeds for our garden.
