SUNPRO 2-Pack Seed Sprouter Tray with Humidity Lid, BPA Free Food Grade Soil-Free Sprouting Kit, Large Capacity Wheatgrass Grower & Microgreens Germination Station for Beans, Peas, Cat Grass (Green)

So, I got the 2 pack with lids because I had two different uses for them. First, I wanted a nice big tray to grow some cat grass for my fur baby. It does the job as well as any sprouting tray I've used, it feels nice and sturdy, and the bottom tray is deep enough for the grass to develop pretty good roots without drowning. The seeds I had sprouted in 4 days (not 5 like I expected), even though I didn't really rinse and drain them as often as I was supposed to. I think that's because I used the lid, which trapped the humid air inside and kept the seeds moist with very little effort on my part. The other use I had in mind, though, was unconventional. I just bought an RV and will be living in it half-time with my cat. I use pine litter, so I needed a litter tray that would let me sift out the sawdust and keep the good litter on top. Regular sifting litterboxes are made for clay litter, so the holes tend to be much smaller, and they're designed in such a way that you keep the stuff that falls through the holes and throw away the stuff left on top. Pine litter is the exact opposite, and it requires larger holes. In my house, I use the (large and pricy) Happy Cat sifting litter box, which is fantastic, but not really compatible with the smaller space of a motor home. But this little tray is just right. It fits in an unobtrusive corner, my cat took to it immediately, and the holes are just the right size to let the sawdust fall through without clogging. Now, I have a pretty small cat. She's full-grown but only weighs 8.5lbs, and she's short (both lengthwise and height - AFAIK she's not a munchkin breed, but I wouldn't be surprised if she had some in her lineage, either). So this definitely wouldn't work for a larger cat. She's also a real princess about her potty usage and isn't prone to scattering litter. And the amount of litter that will fit in this tray is fairly small -- I expect to scoop and sift daily, but so far I haven't had to do so *more* than once a day. You *do* have to put the lid on before you shake and sift, or you'll get sawdust and pine pellets everywhere, but that's zero percent a problem for me. I also put the lid on and secure it with a file band when I'm in motion so that I don't have to worry about spillage. I expected to have to attach a small support to the center of the upper tray to keep it from bowing under my cat's weight, but it doesn't bend at all when she steps on it. It feels surprisingly sturdy, and the plastic is lightweight but thick and not brittle. All in all, much better quality than I expected for the price. If you've got a small space and a small cat who is tidy when using the litterbox, these seed sprouting trays are worth a look as an alternative solution. I can see them being really useful for kittens who are too small to climb over the edge of the Happy Cat box (which is pretty tall, actually) or maybe even older cats with mobility issues. And they're less than half the price! I'm very pleased with them and may end up buying more to donate to my local cat shelter before "Kitten Season" in the spring.

These are convenient and awesome for growing sprouts for my chickens! Shown in the pic with alfalfa seeds sprouting.

I bought these to grow catgrass, and they work great. My only issue with them is that they're large and grow SO much that 90% of it goes to waste. I also am not a huge fan of the plastic mat because the roots obviously grow into it and they're impossible to extricate.

These are fabulous! Perfect for sprouting microgreens. Bottom tray is a good size for the roots to reach the water reservoir. I will be purchasing more soon!

Very happy with this product. It is versatile. You can use it with or without soil, water from below, and the lid keeps humidity high for sprouting. I've been using these trays to sprout sunflower seeds without soil and to sprout seeds in a layer of soil for transplanting into pots. I started 4 packs of onion seeds in soil. I watered the soil down once, put the lids on, and they all sprouted in 4 days. Couldn't be happier and just ordered some more.

Great idea, but you need to be careful moving it due to the high water level needed or it will spill. Only about half of my seeds sprouted! Don't know if it was the seeds or tray. For me, a little to big in size.

I use these to sprout wheat grass for my chickens. Very durable and easy to use! Easy to clean with soap and water.

I began growing grass for my cats and dogs about a month ago. Since I hadn't anticipated the high demand, the small trays I purchased couldn't grow enough grass to keep my babies satisfied. Well...I upgraded to these large trays and couldn't be happier! I used the very same seed mix as before (same bag) for these trays and am blown away by how quickly the seeds germinated and grew. The cover seems to create a humid microclimate that seedlings like, leading to ultra fast growth! Once the blades touched the lid, I removed it and kept spritzing water on the grass every day. Today is day 6 and the blades of grass are around 5.5" tall! I harvested the first batch this morning, and my dogs/cats loved it. Some of the seeds in my mix are really small and fall through the holes. These trays came with a screen, which I haven't used yet. I plan to experiment with the next batch, using the screen for a day or two, during the sprouting phase only, to see if it helps the tiny seed in the mix survive and thrive. These two trays were a wonderful investment. I plan to begin a new tray every week so there's always fresh grass on hand. If you like to grow cat grass or microgreens, I highly recommend this product.

Parfait pour faire mes micro-pousses. Agréablement surprise par la grosseur du produit. Merci

Love these. Use them all the time for fresh sprouts and greens.

affectional and durable

Facile à utiliser

Buried deep in the description is the tiniest mention that small seeds can’t be sprouted in it. I missed it. Now I have to purchase sprouting papers so that I can make this gadget work for my broccoli and alfalfa sprouts. Definitely inconvenient and would benefit from an update to warn people in the description.
