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

Usually, I prefer using wide-mouth mason jars to grow sprouts (without soil). However, I'm using these SUNSPRO seed sprouter trays to grow arugula sprouts which are small and delicate, and have "gelatinous" seeds that would clog the mason jar mesh lids. I'm using coconut coir mats as the growing substrate to prevent the tiny seeds from falling through the mesh of the inner tray. So far, it's working great, even without plant food. The transparent lid acts as a kind-of mini greenhouse that keeps the environment inside of the tray humid. I just put some water in the bottom tray, and spray the sprouts twice a day with water, to keep sprouts and substrate moist. The sprouts seem to be growing quite well at my kitchen window.

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 trays are easy to use and germination rate is very good! The one thing I would suggest is adding to the instructions that the customer needs to put either a paper towel or another growing medium in the bottom of the tray. Most seeds are very tiny and will fall through the mesh if some type of growing medium isn't added. As an experienced gardener,I know this, but a beginner might not.

Works fine

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)

After a few trials, I've gotten cat grass growing down perfect 👌! I don't use the cloth anymore. 1. Soak seeds in 2 inches of water for 8-12 hours in the green tray. 2. Lay 3/4 inch of dry soil in the white perforated tray. 3. Sprinkle seeds evenly and loosely 4. Water gently just enough to moisten soil (I use a spray bottle on mist). 5. Add an additional layer of soil 1/2 inch to 3/4 inch. 6. Gently water until soil is soaked. 7. Cover with lid for 24-36 hours, making sure soil stays moist, spray with water if needed. 8. By 48 hours or so I see little shoots starting and then leave uncovered, continuing to water. 9. At 4 days or so you have shoots of cat grass, day 6 full grass growth. Keep them watered as needed and it should thrive for approximately 3 weeks. That's about the time I repeat the process above with the second hydroponic tray so the next batch is ready for my kitty! The old batch, I just let dry out, lift it up and scrape the roots, turn it over and dump out the old stuff, then rinse it out. Easy easy cat parent (and kitty) approved!

I really enjoy making sprouts with these trays.

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

affectional and durable

Facile à utiliser

The holes in the plastic grid are too big for most sprouting seeds. About all its good for is chickpeas.Brassica variety seeds will mostly fall through. Very disappointed

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.
