Review: Great Sponges! Quantity less than promised + Tip on Preventing Fungus - 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.)
Review: Better than AeroGarden’s seed starters in the plastic pods. - 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.

## Features

- BETTER QUALITY AT A BETTER PRICE: AeroGardens are a great way to grow at home, but existing sponge options are both expensive and of mediocre quality. They are also made from slow-growing peat moss.
- WE COULDN’T FIND A BETTER OPTION, SO WE MADE ONE: Urban Leaf’s coco-coir based AeroGarden replacement sponges work perfectly with all AeroGarden models - offering an affordable, sustainable, and high quality alternative to the ‘genuine’ option. (Btw - we also offer a Liquid Plant Food option!)
- SAVE $$$ ON AEROGARDEN SPONGE POD KITS: Replacement Pod Kits will set you back $10-15 a set. Purchasing the sponges and plastic pieces separately is a great way to save money on your AeroGarden. We also offer a dwarf and compact herb seed collection thats great for indoor gardening.
- MADE IN THE USA: Urban Leaf sponges are made from sustainably produced coco coir and made in the USA. Grow Sponges made from Coco-Coir for optimal root health
- SUPPORT A SMALL BUSINESS: ⭐⭐⭐⭐⭐ " I have ordered these twice now, and I am very happy with how they work and their compatibility with my aero garden. I have not had any problems with these at all. In fact I would say that these are even nicer than the ones that came with the aerogarden seed starter kit!"

## Questions & Answers

**Q: Are these made in the US?**
A: Yes they are made in the US. if you read the info above a Bullet Point is *Made in the USA.
* MADE IN THE USA: Urban Leaf sponges are made from sustainably produced coco coir and made in the USA. Grow Sponges made from Coco-Coir for optimal root health

**Q: How long will the sponges last since they are moist and may grow mold over time?  I only use a few sponges in a year.**
A: These sponges will indefinitely if kept dry. Once they are wet & in use I have had them last as long as 18 months. (at which time I was removing the plant due to no longer wanting the plant but the sponge was still good) If during use you find any algae on it, & this is usual, you can take a QTip & dip in some Hydrogen Peroxide or vinegar & gently wipe it off. I hope that helps.

**Q: will these sponges work in ecco grower aqua 1 ?**
A: Hi Kathleen, I'm not familiar with that unit sorry, but as long as the size works for you (show) there's no reason I can think of that the material wouldn't. These are made from coco coir which is a fairly common hydroponic substrate material. We prefer it to peat moss as it is more eco friendly and the coir is a little better for water chemistry management. Best, Nate

**Q: Do i need the liquid nutrients?**
A: Yes - these are just blank sponges, so you will need to separately add hydroponic nutrients into the reservoir.

### ⭐⭐⭐⭐ Four out of five sprouted.
*by K***Z on April 13, 2020*

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!
