RooTrimmer Growing Trays, 1020 Plant Nursery Trays Heavy Duty Seed Starter Flat Seedling Tray for 72/128 Cell Plug Tray Transplant Growing Microgreens (21"×11", 10 Pack, 1.6" Deep, Without Holes)

5 star. Excellent quality and durability. I won’t purchase the other cheap flimsy trays ever again. These will last a life time and I need to order more. Well worth it!

These worked really well for me. They are a little more shallow than the Ferry Morse trays I already have. They won’t stack with them either. But sturdy, well made and fit my budget.

Heavy duty, will last !

Very sturdy trays, will definitely recommend these trays.

Very sturdy! Highly recommend! Can use again and again!

Before buying 1020 trays a person needs to understand what else they're buying to go along with these trays. There isn't really standards for these types of trays so you can buy inserts such as cell trays and then find out they don't match the 1020 tray you bought. These are a shallow tray which is good for SOME of the 72 and 128 cell trays, but not the deep ones. I've mostly bought deep 72 cell trays and they don't match these. One way to solve most the problems other than looking at dimensions for everything is stick with one company or another. I like the longevity and strength of another company's line so I mostly use their products. I also like the fact that their cell trays are deep as that gives roots more area to move into before transplanting. Depending on how you like to transplant and the type of seed you're growing that may be good for you, maybe not. The main point is there's no magic bullet when it comes to these types of trays, however there are the more expensive ones from one company that are rated to last years, while some of these trays will start to deteriorate over a few seasons and then the recommendation is to get rid of them because you get more microplastics into your seedlings by continuing to use ones that deteriorate quicker. This is a type of plastic that's going to start breaking down. You will need to replace these after a few years. The company doesn't say that when I read the product information, but considering this is basically the same type of plastic as ones that do I have to think these do too. To recap, if you want deep cells then these aren't the right trays. Make sure you match cell trays to flat trays so you don't waste money. Next, if you want more than 8 - 10 years out of your trays there's only one company that uses a type of plastic that will last longer than that and it's not Rootrimmer. They're also stronger and stiffer, and cost more. These trays are not a one time investment but they'll last close to a decade, maybe a little longer if you don't use them outside. If they're always outside you probably don't get a decade out of them.

Good price, great size for what I needed, plastic was thick and durable, very good for starting a lot of seeds or just using them for bottom watering.

Nice and thick, has a thicker than normal lip at the top. but they are shorter than the average tray and slope in more. This means instead of 9 1/4" width at the base it is 8 3/4", this mean I cannot put 3" pots all the way across, I have to use a combination of of 2 and 3" pots or settle for my pots leaning on the edge. I know no big deal, until you pick up the tray to move it and the side pots fall over.

Very sturdy! I ordered these for starting 6 packs of seedlings. They are a little shorter wall (1.6 in deep) but very thick. I realized that these are also available in the deeper (2.35 in) trays so I ordered 10 of those also. Good trays!

Happy with the quality, wasn’t sure what to expect. Ordered the 128 cell flats also, fit like a glove. Solid product, better than I could find at my local stores.

Very heavy will stand up

How can such a simple thing go wrong. They didn't. Work fine.

Flimsy!!!! poor quality.
