About this item

  • Broad Compatibility: Once soaked, the grow sponges expand to 2.56 inches in height and 0.9 inches in diameter, making them compatible with most hydroponic growing systems on the market. Whether using seed starter pods with grow baskets or specialized seed starter systems, you can ensure reliable germination and strong root development. These hydroponic pods also work well with seedling trays and potted plants, suitable for indoor gardens or outdoor planting.
  • Superior Growing Medium: Our grow sponges are crafted from 100% biochar cotton, known for its enhanced fertility, which supports robust plant growth. Compared to conventional seedling soil, these grow sponges maintain a balanced pH and offer excellent water absorption and moisture retention. This provides the ideal environment for seeds to germinate and roots to establish, while ensuring a mess-free, soil-free indoor growing experience throughout the year.
  • Optimized for Growth: Each seed pod features a small hole at the top to keep seeds securely in place, preventing them from sinking into the water. The seed starter kit are designed with small grooves around the sides to promote water circulation and maintain optimal humidity levels, ensuring seeds receive the moisture they need for successful germination. These grow sponges are easy to replace—simply remove the old one and insert the new sponge after soaking it for 3-5 minutes.
  • Value-Packed Kit: This set includes 80 replacement grow sponges, providing you with ample supplies to start multiple seeds at once, saving you time and effort. (Note: Seeds are not included in this kit.) The dry sponges are easy to store, ensuring they remain in top condition, ready to support your plants’ growth without any concerns over quality issues.
  • Versatile Application: These grow sponges enable you to cultivate a wide variety of plants in your hydroponic indoor garden, regardless of season or location. Grow strawberries, tomatoes, basil, mint, herbs, flowers, lettuce, and more with ease. This seed pod kit also makes an excellent gift for gardening enthusiasts, offering a simple and effective way to grow vegetables, small plants, flowers, and more.

Good quality for the price. It looks like it’s going to give a better germination rate than others I have used since there seems to be a better deeper divet in the center to hold the seeds.

I got these for my daughter's hydroponics setup. They work fine, and they're a lot cheaper than paying for the specific brand!

I read a lot of reviews on this and similar products and choose this because they sounded like they would fit and had good reviews. They do fit fine, but this is the only thing I have changed and now my seeds aren't germinating. I've used the same seeds as in the past, and so it has to be these. Also, when I checked on the seeds, it seems like they just molded in these plugs. It's a bummer since they did fit well, but useless if the seeds won't germinate in them.

One big thing to keep in mind is that you are only getting 80 sponges, no seeds, no netcup/basket, so don't get confuse by the pictures of this item. The sponges are very good, it's a typical size will work like the original included from aerogarden machine. For me, I use this on my DIY hydroponic setup with styrofoam board sitting on top of my golf fish tank, it's working well. I've been growing herbs like cilantro and mints, just make sure you have the right amount of light, air, temperature and good circulation water, it will on kratky method as well I'm sure.I don't think there are any good amount of nutrients in the sponges, so it's ok to start seedlings, but you need to add nutrients once the seeds sprouted and it will use a lot of water and nutrients once it's fully rooted, so keep an eye on it especially if you're doing the kratky method.

They work great! They fit like official sponges. I've had no issue with them.

I ordered these because I was running low on my sponges that came with my Aerogarden. I was a bit skeptical at first sight because they looked shorter and felt a bit more tough than my Aerogarden sponges, but performance wise, I could not term the difference at all. My lettuce grew at the same rate and quality using these sponges as it did with the Aerogarden brand sponges.

I am a huge fan of hydroponic growing, however, I also find these grow sponges to be effective for rooting cuttings as well, so I try to keep a good stock of grow sponges on hand. These sponges are very good quality, they rehydrated quickly and did not break down like some cheap products.There is a little hole for seeds, I like to make the hole a bit deeper for cuttings.
