    • Great seed starting trays
Size: 40-Cells 5-Pack
So far these seed trays are great for the price. I love that they have a tray to contain water dripping out. The top clear dome has vent holes which is great to give your seeds fresh air. I love that it comes with 5 trays and is made sturdy enough I should get many years worth of use out of it. The size is a great starting size. ... show more

    • Very nice and economical trays!
Size: 40-Cells 10-Pack
These are very nice quality. Good enough I would have spent twice as much. Not flimsy at all. The domes don't lock on in any way, so they slide off easily, and that is my only negative. They fuction great, are easy to move, and are just all around a nice, solid investment. Definitely 5 stars at the price point! ... show more

    • Sturdy & perfect for starting seeds indoors
Size: 15-Cells 10-Pack
I purchased the 40 cell 5 pack and then decided to order more seeds and purchased the 15 cell 10 pack. Heads up that the 15 cell trays have larger holes than the 40 cell trays; my bad for not realizing but it will give the starts more time to mature before needing to up-pot. Great sturdy trays that allow for bottom watering. This is my first year starting seeds at home but I left the humidity domes on without the round circular inserts to allow humidity with some air flow until ~80% had germinated then removed the domes. I only had to lightly spray the trays once while the domes were still on so they do help with moisture retention. The humidity dome is sturdy enough to prop under the trays after removing so that the plants can be closer to my grow lights. ... show more

    • Wonderful trays
Size: 15-Cells 5-Pack
Good seed starter trays. 2 were cracked in the bases but still work decent, we just put a drying dish mat under to keep from messes happening. Holds in the humidity super well and our seeds sprouted faster than expected in all except the cracked ones. I would give 5 stars if it wasn't for some damaged ones because they are great and easy to use. ... show more

    • perfect size
Size: 15-Cells 5-Pack
great seed starting trays. Like the fact that they have a vent I can open or close. Perfect size for the plant shelves I ordered recently. sturdy and well made so I should be able to use them for several years to start plants from seeds.

    • Decent trays
Size: 40-Cells 10-Pack
You know what you’re getting with these. No surprises. It’d be nice if they were sturdier and lasted longer, but any trays you get are going to be thin and fragile.

    • 4.5 stars. Not quite perfect, but a great deal!
Size: 70-Cells 5-Pack
For the size, sturdiness, and PRICE it is a great deal. The cell size is decent, and if you're considering the type of tray with many small cells already, then you already know what you're using them for. I did go back and forth between 4 and 5 stars solely because it truly is IMPOSSIBLE to push the venting covers into place. It's so difficult, you will need tools made of metal to do it. Ultimately, though, unless you need a super humid starting environment, you won't use the covers much, anyways. I bought these for winter sowing, and I was planning on drilling more holes, anyways, so I didn't even bother to attach the vent cover. Good quality trays are insanely expensive, and these are sold at a great price. Perfect for beginners (besides the covers) and for winter sowing. It seems like they'll last for a few seasons, at least. ... show more
