20 Pack 1020 Trays, No Drain Holes, 20" x 10", Extra Thick Heavy Duty Seed Starting Trays -Reusable Propagation Flats for Microgreens, Seedlings, Plant Germination, Fodder and Transplant

I recently purchased the heavy-duty 1020 tray packs, and I’m really impressed with the quality. These trays are durable and ideal for seed starting, holding up well through repeated use. The bonus of getting a two-pack of heating pads, practically for free, was a great surprise. The pads work well to provide consistent warmth for healthy seedling growth. Overall, this combo offers excellent value for the price, and I’m very satisfied with my purchase. Highly recommend for anyone looking to grow plants in a controlled environment.

Very nice and sturdy trays. Helped to hold water for hot summers

Very sturdy will last a long time worth it

These root trainers are very durable and I use them to water my seed trays from the bottom. They are the right size to put trays of six packs in. They are a good weight I don't have to worry they'll buckle when moving. Great value and I keep them out of direct sunlight to keep them from getting UV and brittle.

Very sturdy

I bought two sets of trays. They are of uniform size, shape and design. The trays are thicker than other trays I’ve bought which is quite lovely. They don’t appear to have any imperfections in design.Good, trays are thicker than others, solid and don’t fold as soon as you load them. Tested with 20lbs.Cons, I’d like them a bit cheaper. In my personal opinion, they are about 15% more expensive than need be for what you get.Overall, good quality and uniform design.

Very sturdy--should last a very long time. I got the 5.5" pots and the 1020 trays. Both are just what I was looking for. No more flimsy pots and trays! I plan to order some smaller pots for seed starting in the fall.

These are sturdy enough without being excessively heavy. (They're much thicker than the ones you usually see at a big-box hardware store. I use them under potted orchids to provide extra humidity and prevent spills. At the top rim they actually measure 11 inches x 21.25 inches. These trays are 2.5 inches high from outside bottom, to top of rim. The base footprint is the "10/20" reference. Be aware of the overall size if you plan to use these on a plant shelf or in a tight space as I did. I was lucky, they fit snugly between the legs of my light units.
