50 Grow Sponges for Hydroponics - Seed Pods for Garden Seed Starter Pods Growing System Plant for Seed Plugs Garden Cube Sponges Replacement

These sponges arrived smaller than I expected, but they did match the size guide shown in the listing, so that was on me. Once I soaked them in water, they expanded to a good size. They’re still a bit smaller than the sponges that came with my Growell hydroponic system, but they’re close enough to work well and feel like a great value overall.The material holds moisture nicely and provides good support for seedlings. I tested them with pumpkin seeds, and while I could fit two seeds in each sponge, it was a tight fit. If you’re planning to use these for smaller seeds like herbs or lettuce, they’ll work perfectly. For larger seeds like pumpkins, squash, or beans, I’d suggest going up a size for better breathing room.That said, I’ve already grown a handful of happy, healthy plants with these sponges. They’ve held up well, stayed moist without falling apart, and made the germination process really easy. If you’re working with a compact hydroponic setup or doing seed starting indoors, these are a great option.Pros:✅ Expands nicely when soaked✅ Holds moisture well and supports good germination✅ Great for small to medium seeds✅ Affordable and matches the description✅ Compatible with many hydroponic systems including GrowellCons:❌ A little too tight for larger seeds like pumpkins or squash❌ Slightly smaller than my original Growell sponges

This item fit perfectly in my aero garden. They came air sealed which was good because it kept them from breaking. Would purchase again.

These were okay. Skinny compared to what came with my kit. The plants are not growing as fast.

They came in a vacuum sealed package, which kind of had the seed hole pressed flat. Also, they are not as large as I was needing for the original replacement I needed. Other machines might be smaller so they might fit those but it doesn't fit mine great. Nonetheless I will see if it still works. The plant will just need to grow an inch before it clears the top of the water container.

Quality replacement plant growth sponges. They are a bit smaller than the original. They are reasonably priced.

I’ve had aerogardens for years. These are good choices to start new plants. Fit completely and has area to tuck seed in.

When I receive these, they were Vacuum impact so tight that they stayed out of shape until wet. They are very dense, not like previous pods. I have purchased from other vendors. I have been using my hydroponic grower for vegetables for years. Purchased these pods for the first time because of the price. Wasted money. Tried multiple times and nothing would sprout, or sprouted and never grew to a healthy starter for transplanting. Missed my return window due to trying multiple times thinking it was a fluke. Now tossing them in the trash. Lesson learned. not all grow pods are created equal.

Repeat purchase of these type plugs. Never an issue. These were oddly packaged and vacuum sealed for whatever reason but they'll work fine.
