Great for winter growing!
I used these trays to sprout barley for my chickens in the winter. They're pretty shallow so they work for drip trays for indoor plants, too. Very impressed with quality, I've been using them for a year and no cracks or chips!

Sturdy & Reliable – The Perfect Dome for Healthy Seedlings!
This heavy-duty humidity dome fits perfectly on my 1020 trays and is a major upgrade from the flimsy ones I’ve used before. The plastic is thick and durable, holding up well to repeated use and cleaning. It retains moisture effectively, creating a stable environment for seed starting and cloning. The vents on top allow for easy humidity control, which is great as seedlings mature. Highly recommend if you’re looking for a long-lasting, reliable dome for your grow setup.

Do not fit trays from the same company
Was disappointed that these do not fit the trays ordered from the same company. Would return but needed to get planting and am just balancing them on top

High quality, sturdy, long lasting seed tray dome lids!
Very sturdy, high quality plastic seed tray domes lids. They have lasted me two planting seasons so far and looking to last even longer!

Nice quality
These are a good price and quality. They will last for years due to their sturdiness.

Very shallow, will melt in the sun even in diffused light
The plastic is at least thick enough that they don't split, but they will *melt.* We have a hoop house that has a clear white plastic cover that we use to start seeds and to propagate plants. I had 2 of these trays stacked with wet soil and seeds, covered with another tray. Even in the diffused light, the cover tray melted. Also they are so shallow. Like not even an inch deep. They're ok for my purposes because I'm just making seedlings to feed to my chickens, but I will not purchase any more of these. They are so small it's like a snack for 2 chickens.

GD545 humidome
I ordered td542 and gd545a from you on mason. Excellent product. Then I decided to order gd545 humidome off Amazon as well because your description says it would fit the td5542 tray. Well it doesn’t fit. It is to small and it will not fit any 1020 tray. I can not believe you can make one product that fits like a glove and the other humidome (gd545) that is absolutely junk. This is being returned. If I read your reviews on gd545 before purchasing, I would have not bought. This going to placed in your reviews on Amazon as well. You should fix the problem instead of screwing people out of money.

I really like the strength and durability of these domes and they fit over my seedling tray very well. They really help to maintain the moisture level for seed germination as well as maintaining the warmth.

I am absolutely livid that these domes do NOT, in fact, fit ANY 1020 trays. There's no possible way that the seller isn't aware of this, however, they STILL continue to claim that they do; it's a bold faced lie. Honestly, I feel that Amazon should have the right to FORCE these sellers to be honest in their product descriptions, otherwise they should be responsible for eating the return charges. Why should I be responsible for paying to ship these garbage domes back, when I only purchased them based on the lie that they would fit? I can't even use these for anything else, so, they're essentially garbage... Actual garbage. They will NOT stay on top of the trays, as the width is the EXACT SAME SIZE!... So, they just slide around, falling over the edges of the trays, as there's no where for the edge to rest. Like I said... There's NO POSSIBLE WAY that the seller is unaware of this, but they just go on lying to customers, and essentially robbing them of their hard earned money. Do better. Be honest. Change the product description so that everyone will KNOW that these DOMES WILL NOT FIT ANY TRAYS; 1020 or otherwise. This is just disgusting marketing, imo. I went ahead and ordered domes that WILL properly fit, from Indoor Farmer; I highly recommend everyone to head there. Do NOT purchase these if you need them to properly fit 1020 trays. They won't fit.

I ordered these 1020 covers for my 1020 trays and they don’t fit! They are nearly 1/2 inch too short and 1/4 inch too narrow. Very disappointed. :(
