10x20 Inch Black Plastic 10 Pack Plant Propagation Tray No Holes | Growing Trays For Garden, Planting, Seedling, Soil & Hydroponic Horticulture - Microgreen Trays Grow Plants - No Drain Holes

These domes are good quality: sturdy and well-ventilated. They fit the trays offered by the same supplier. I had to order the trays separately. The supplier should offer the tray-and-dome combination for convenience and at a favorable price.

I'm very happy with the quality of these domes. They are quite sturdy and the height is AWESOME. One was missing from the pack, but customer service was awesome and is sending me a replacement without a hitch. Now I get to stand back and watch my babies GROW, BABIES, GROW!

Very good deal for the price. Use them all the time.

Recently purchased these domes. Not as sturdy as I had hoped but purchased again because of their versatility. 1) Propagation indoors on a heating mat with plenty of headspace for when they are transferred outside, 2) can be used outside as a rain guard over trays with drainage holes, very important to me because I utilize sunny space along the south side of the house that takes the full brunt of roof/eave rain runoff. The domes can be placed over plants when rain is expected rather than rushing out and moving trays all over the place to more protected areas; 3) The tall domes fit perfectly between my outdoor shelving . . . which will protect seed trays from birds during during warm-weather germination and (later) plant protection from nighttime critters. And because of the snug fit between my particular shelving, I no longer have to worry about wind blowing off the domes. Fits my needs very well . . . just wish they were sturdier.

They are very thin so you have to be careful of the amount of stuff with weight that goes in it to grow your seedlings

These are 10x20s and are fine when flat, supported on a table or shelf. They are watertight, as advertised. They are too flexible to be used to carry starts, however. They tend to warp however you carry them, so I use 2 or 3 at a time when potting out starts.

Works great for what I use it for. These fit perfectly on the shelves in my room, then I put the smaller planters in these trays so any dirt or water that comes out of the planters stays in the trays. Easy to use and seems durable

These trays ended up being a no for me. They are standard 1020 trays, which is the main upside, but they are extremely thin and flimsy. I had issues with them bending, dropping things, and generally not feeling stable enough when moving seedlings or supplies around. To make them useful, I often had to double or even triple them up. In several cases, I ended up moving plants or materials into better-quality trays because these just did not hold up well enough. They may work for very light-duty use, but I would not recommend them for seed starting or anything that needs regular moving, carrying, or watering. I would spend a little more on sturdier trays next time.
