5 Pack : Plant Tray Clear Plastic Humidity Domes: Pack of 5 - Fits 10 Inch x 20 Inch Garden Germination Trays - Greenhouse Grow Covers

We all know how flimsy, cheap, and thin are the covers that come with most multi-cell sets. Out of desperation, that’s what I THOUGHT I was buying.Now don’t get me wrong... $5.50 for an ounce or 2 of plastic?! Somebody’s making out pretty nice on these lids.But aside from that, I’m very impressed by their build quality. They’re heavier and thicker than any others that serve the same purpose (at least, that I’ve ever seen). They also fit the base with a little more wiggle room than others — which I think is a benefit. Not so much as to let out heat, though.I just got them today, so I haven’t used them, and obviously can’t rate them on anything having to do with length of life, or such.I just wanted to pass along that they APPEAR to be high-quality lids... just in case, like me, you’re waffling on buying them because they’re so outrageously expensive.*** UPDATE ***Indeed, they ARE well made! They honestly hold the moisture better and longer, due, I think, to their (heavier) weight. Very happy I bought them.

Quick delivery and lids fit perfectly. Happy to recommend

I have excellent luck with these fitting just about any seed tray I have.In fact, I replaced all of my "Jiffy" lids this morning with these guys.They have a great fit and stay on in high winds.Would recommend these.

These covers are very strong, could be a little taller. But they do the job and are sturdy!!

These were great fit 1020 trays perfectly
