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)

I really enjoyed the quality and fast shipping. It is rigid enough to hold a full tray of seedlings as I walk through the greenhouse and not feel like it will not break. Its lightweight, fits my standard 50 cell count tray and does a great job of maintaining the moisture and water levels needed. The ridges built into the tray are great and are extremely useful.

Functionality:These are great. Fit my seedlings and are strong enough to hold with one hand during transport. Really like them and after washing they seem ready to go for next years seed starting. Great purchase.

I needed some sturdy trays and these are sturdy. They are going to last a very long time

These are excellent, very sturdy. I am able to load these with heavy pots and they don’t buckle! I will be replacing all my cheap trays with these. The standard size pots fit perfectly in the trays.

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.

I like the size and they are pretty sturdy. Only issue is if I’m moving them when full of water is they sag at the corners a bit so I have to be a little careful. They fit 12 of my 3” net cups each. I did find some cat litter containers I can reuse that these fit perfect in so that’s pretty cool.

The quality is exceptional. Had to bought another set

Solid! These have been through thousands of seedlings so far this year and not a single one has cracked.
