Nothing growing yet ??‍♀️??‍♀️These do not fit the models listed as compatible. I haven’t gotten anything to grow in these, I had much better luck with other brandsThese grow sponges work great. I have a generic table top grow system that looks like a clone of the Fafagrass system. These worked well in it. They are more dense, even after expansion in water, compared to other grow sponges I have used, so I can see why they cost more. I did not like the slits at the top in place of a hole. I found that I had to pull it apart or dig with an awl to make a cavity for the seed so that it didn't fall off or get washed away. I also tested these out in my ebb and flow system using 2" net cups. It worked well, but I had to throw some clay pebbles in to fill the gaps. These are good grow sponges, but ultimately the longevity gained from making a more robust product is, in this case, not worth the cost. These are one time use sponges and there are cheaper options available that also work well. If the cost (0.50 cents each at time of review) on these comes down relative to other available options then I would recommend the Fafagrass grow sponges over any others that I have tried. The bottom line is if you are willing to pay a premium these are good sponges.The FAFAGRASS Grow Sponges Compatible with Aerogarden Seed Starter pods for Hydroponic Indoor GardenPack of 30 I'm a fan of.It shipped well with minimal packaging. It emitted no weird odors or chemical-like smells. It was sealed well and there were no signs of tampering mold or the like.The bag is great as it is re-seable. I can use the sponges I need at the time and store the rest of them for later. The packaging states these are breathable, non-toxic, & soil-free. It illustrates and instructs to do the following; place seed in the hole, place in grow basket and cover with germination cover. I can use the sponges I need at the time and store the rest of them for later.These work in my hydroponic gardens ( I have a few different brands). That said these can be a little tall for some of my indoor gardens but can be trimmed down. I have had no issues with roots getting bound and not growing through or these not fitting well enough with some slight adjustment.I have had herbs and lettuce grow in these very well. I am happy with the price and the fact they work so well.Highly recommended.I am accustomed to having an actual hole on top to drop a few seeds into (so I simply indent the top with a screw driver tip). The sponges themselves are absorbent, and have worked efficiently for me so far.• a little smaller for my hydroponics system but it's alrightI am using these cones as refills for my Hydro growing systems. Now grow sponges usually last many growing cycles but some of mine have been used for a very long time. I actually started using them a few days ago and as you can see from the picture they work great! That is roman lettuce if your wondering..lol These sponge refills fit most models of hydroponic growers I have 7 different modules and it fits 6 of them. I am very happy with these sponges because they are very affordable and very durable. You will be very happy with them as well. I will be using this seller and brand exclusively for my grow opp because you can't beat the price or the quality!I have an off market hydro garden, and these worked like a champ. Of course, there is a learning curve as well as a good understanding of seed germination. I totally got mixed results but I am convinced it is due to my self educating and not the fault of these pods. The pods performed exactly as described.
