Hydroponics Sponge Grow Sponges [Pack of 50] – Organic, Sustainable, USA-Made AeroGarden Compatible Refill Sponges – 100% Coco Coir Seed Sponges – Garden Sponges with Seed Divots by Urban Leaf

After ordering the 50 pack replacement sponges (non-Aerogarden brand) only about 45 came. They likely had their weight threshold off in their manufacturing. I let the seller know and they sent another bag STUFFED TO THE BRIM free of charge. Note that these have the hole punched in random places instead of always in the center. I promise your plants don't care as long as they have clear view of the light. At first I used taped on saran wrap to simulate the iron on transfers. I had an X shape cut into them. I eventually realized my seeds don't care if it's open air, so I stopped using saran wrap. Just reused plastic holder + this sponge + sometimes the clear plastic seed cover/cap (read on to see why I recommend skipping the cover/cap). I had mold issues with every seed I planted after the first round of plants established themselves. (I.e. not starting over with every pod - just a few). 0% success rate with each one. I tried leaving the cover cap off the seeds and success went to about 50 success. (Note that when a seed failed due to being covered in mold or fungus, I would remove the dead seed, run water over the sponge while on a plate so that there's a small pool of water, and microwaved the sponge (Only the sponge! No plastic pod.) Until there was a healthy rapid boil and tons of steam. Any algae in it will turn to these bright green clumps. Once it cooled, I ran the sponge under cool water to make sure it was completely cool before putting a new seed in. I brushed the plastic pod with a toothbrush to remove any green algae or fungus spores, sometimes with dish soap, sometimes not. This is what gave me the 50% success rate. If you don't do that and reuse the fungusy sponge you'll likely still have a 0% success rate even with the top off. Replacing the sponge with a new one would also work but why waste them? To get the rate close to 100% success while having other established plants, I waited till the Aerogarden needed more fertilizer and then I cleaned the Aerogarden unit. (This is on an Aerogarden Harvest unit.) To do this, I pulled all the plants out. Any new or young seeds/sprouts were manually removed from the sponge (the others were too established and could not be removed). The removed sponges were microwaved after being put on a plate. Once cooled and had cold water run over them, the seeds/sprouts would be returned to the sponges. The plastic pods that could be separated were all brushed with a toothbrush, with or without dishsoap. The white plastic top that holds the pods was removed from the water basin. Pressing on the tabs on the white top one by one separated the 2 pieces that make it up. This was scrubbed with dish soap and a toothbrush. The water in the basin was dumped and the inside was lightly scrubbed with a soapy sponge. The little sponge in the basin that protects the pump was removed, root bits were extracted and the sponge was cleaned. Because I keep fish tanks, I know that sponge will grow a harmless naturally occurring bacteria and eat some of the ammonia and nitrites from my fertilizer instead of letting my plants consume it. I typically wash this first, squeeze the water out, and let it sit out to dry. The bacteria dies within 5-15min of this and if I cleaned everything thoroughly it would take about 6 weeks to re-establish. Given that I likely don't get every nook and cranny, it probably re-establishes itself faster. Who knows if this is helping my plants much but it gives me warm fuzzies knowing they're getting a tiny bit more amonia and nitrite nutrients. Once all the soap is rinsed off, double check the power cord attached to the removable basin to make sure it's dry. Fill the basin and put everything back together. Put the plants back in, leaving the caps off the seedlings and seeds. Add your fertilizer and you're ready to go. This cleaning process skyrocketed my success rate with the seeds. I like to think it's because I killed the bulk of the spores in the water making it work that much harder to come back. By the time it has a chance to come back, my seedlings are established and seemingly naturally resistant. (I use all organic seeds, so there's no pesticide help.) I highly recommend these sponges. They look wonky but they totally work. (And note that the Aerogarden brand pods might look less wonky but they have the same mold/fungus issues.)

These seed starters for the AeroGarden Hydoponic grow plastic holders work far better than the seed started from AeroGarden. They come apart a bit easily, so you have to be gentle with them and may find a damaged one or two per bag. However, to me the function and the excellent functioning of these seed starter pods far outweighs any minor loss in the bag of them from damage in package or done by me by accident. These are the bomb. In fact, I started a grow in my AeroGarden with the AeroGarden pods first, but some did not germinate properly, so I lost all my herbs and most of my highly prized seeds which have been difficult to replace given the time of year. Starting over in August with an herb garden makes procuring seeds difficult, because of the time in the season it is. However, once I got the seeds, the pods (seed starters) in this bag allowed my seeds to germinate quicker and more assuredly. My garden is on and growing because of this product. A definite must buy and use for any AeroGarden Gardener growing with their own seeds. I highly recommend this product to all.

I followed the instructions and planted my own spinach seeds in these pods. Four out of the five sprouted just fine. The fifth one had signs of mold and never sprouted. Not sure why one would have this problem when the others in the same AeroGarden did not. But with such a large supply, I simply tossed the moldy one, did a bit of cleaning/wiping down, and tried again with a new pod. We'll see what happens! Happy that I will soon have fresh spinach without having to go out to the store during the Coronavirus lockdown!

I have gone through 2 bags in about 2 years. Great little seed pods that I’ve been able to sprout seeds in every time. I love they aren’t made overseas. Some of them are a little funny shapes and sometimes I need to adjust the whole but for the cost it’s a great deal. I use them in a brand name hydroponic garden and I just put a little aluminum foil over the top and poke a hole to prevent a lot of mold.

I bought these because I wanted to use my own seeds for planting in my aerogarden. I would be doing a lot of pods so I thought this would be a good deal. I was wrong. I am not real happy with these. For some reason I have a very low success rate with them. After they are in the water for a short period of time they develop mold & slime on them. It isnt due to algae in the water because I also have pods that came from AG company that dont have this problem. I have had to discard the majority of the plants I seeded in this medium due to algae & failure to germinate. The other problem I have had with these is on almost every plant that did root in the aerogarden when I removed it, removed the plastic basket & planted the root mass in dirt the plants have died. I have never had this problem in the past. This medium just isnt up to my standards & I wont be buying any more of these. I guess you get what you pay for. I would not recommend this product to sothers but I would inform them of the issues I have had with it.

using these without issue in my AeroGarden Harvest. bought these 3rd party sponges and 3rd party baskets on amazon and just using regular big box store seeds i've had lying around. Interesting thing is how quickly everything has germinated. Tomato's and basil (far front left) are about 6 days old in these pics and the thyme is only two days old (middle two) and have already germinated. very happy with this. and fyi - these sponges release nicely from the baskets when transferring to soil so no need to cut the basket. just be sure to have an eye on the size of the roots and transplant accordingly. Anyhoo, the large tomato plant is about 12 months old (indeterminate) and the soil is pretty much depleted so i started another run (babies) shown in tent. these new tomato's (aero) will be given away to neighbors with similar set ups. all in all, the sponge are not exactly perfectly formed to fit the baskets but work fine. definitely recommend.

Too short for my pod.

Amazon has now asked about a bazillion times about my purchase of dirt. It's dirt. Okay, it's actually a type of sponge but I don't care. They (mostly) fit inside my Aerogarden and they (generally) stay together and don't fall apart and let me (usually) plant seeds into the center and then: water + light + time + seeds = plants and herbs. They are cheaper than the ones I can get directly from Aerograden, do the same thing and 80-95% show up in one piece depending on how rough the delivery guy handles them. Or as an old farmer who lived by my house when I was growing up used to say: "buy dirt because they stopped making it." He's dead now. And likely dirt. Enjoy!

These are by far the best repacement seed sponge pods I have bought so far for the Aerogarden. I like the fact that they are kept a little moist in the paper bag. It makes planting very convenient. Place the sponge in the pod and place your seed, cover and voila. No waiting time for the sponge to get wet.

Pour 25 pod utilisés, seulement 2 semences ont germé et n'ont pas atteint 1 po de haut et ceci en plusieurs semaines (J'ai un système avec irrigation automatique). J'étais emballée par l'idée de la fibre de coco comme matériau de fabrication, mais ces pod de croissance ne contiennent probablement pas de nutriments ou ne le retiennent pas. De plus, ils développent bcp d'algues et de moissures qui se propagent aux semences, qui finalement entraînent le défaut de germination.
