A bit early to tell, but these seem to work as listed. Good for starting seeds in a hydroponic system.

I’m just getting started with these, but so far they’re working great in my DIY Kratky system. They’re easy to saturate and hold their shape really well, even after a few soakings. The square shape fits snugly in my grow containers, and the texture allows for easy root development. Excited to see how my seedlings do with them as they grow!

These grow to a pretty big size once they get wet. Depending on your set up they fit nicely. They provide a good germination place for your seeds in your hydroponic set up.

These are exactly what I expected them to be. You do have to submerge them in water before using them, but it is a quick and easy process. They become slightly bigger after submerging. There are a lot of them included for the 19.99 current price. It has been almost a week and have not had anything sprout as of yet, but I feel confident that they will.If not, I will update this review!

I am using these for seed starting for my vertical grow garden, I am not using it for hydroponics. They easily plump up in water and I am keeping them in a grow tray. I like this so much more than the plastic starter pots which don’t last and this doesn’t have plastic waste. Love them!
