SUNPRO 2-Pack Seed Sprouter Tray BPA Free PP Soil-Free Big Capacity Healthy Wheatgrass Grower Sprouting Container Kit with Lid (2, Green)

Works great. Must keep an eye on water level or grass dies

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.

I like these a lot. I am able to make batches of fodder for my chickens and parrot.

Great product. Easy to use, works great. I've had other sprouters that were alot more work to use requiring frequent rinsing and monitoring . This one is easy to use and the sprouts hold up well for days after sprouting .

I really like this sprouter. I like it much better than bottle sprouters. It's easy to access the sprouts, and cleaning is simple. I line the sprouting tray with cheese cloth which makes harvesting the sprouts and cleaning up the sprouter easy. It also helps when using small seeds.

These are merely ok, neither good nor awful. For me, the flaws are this:> The bottom tray is too deep, and leaves too much vertical space underneath, causing the root radicals to dangle straight, instead of tangling together to form a secure and healthy root mat. Without a proper root mat, any attempt to upend a tray to shake out unsprouted pulses (to discourage mold/wilt) causes many of the sprouts to simply dump out.> The clear dome lid lacks adjustable humidity vents (I drilled a bunch of 1/4" holes on all 4 sides, to improve ventilation), and the top is sloped inwards from vertical, which precludes it from being used upside down to weight down the sprouts during germination. The lid is also not quite tall enough to accomodate mung bean sprouts.> I'm not a fan of the non-standard size. Most standard size trays are 10x20, so a more logical and cross brand compatible size would be 5x5 (8 per tray), 5x10 (4 per tray) or 10x10 (2 per tray). If they'd sized it like that, and maybe offered an optional support rod, they'd work well inserts into a larger 1020 tray system, instead of just a stand alone setup. A missed opportunity, IMNSHO.I will probably end up recycling these, once I evrntually upgrade to a rack system (perhaps a 6 tier NSF design, with shelves that are 14d x 30w, 18d x 48w, or full size 24d x 48w . . . I'd prefer the former, but most grow lights seem sized for 48" racks)

I love this sprouter, but you better have a restaurant or a family of 4 or more as these make a lot of sprouts. They work well.

These are nice in principle. When following directions, the grass does grow almost nicely. Some chunks grow out of the mesh instead in into it, leaving clumps of grass that can't reach the water source. Another problem is when my cats go to eat it. My cats pull on the grass, which then uproots it from the tray; seeds, roots, and all. It may be that my cats try to eat it before the grass is tall though. Hopefully this uprooting won't be a problem once the grass in fully grown, but I won't be finding out. I'm returning these bad boys.
