Features

  • Optimal Water Retention: Hydroponic grow sponges are designed to retain the right amount of moisture, ensuring that plants receive a consistent supply of water without the risk of overwatering
  • Sterile and Disease-Free: These sponges are sterile, reducing the risk of soil-borne diseases and pests that can harm young plants during the germination stage
  • Efficient Root Aeration: The porous structure of hydroponic grow sponges allows for excellent air circulation around the roots, promoting healthy root development and preventing root rot
  • Biodegradable: Our hydroponic grow sponges are made from biodegradable materials, making them an environmentally friendly choice compared to traditional soil or plastic-based growing mediums
  • Easy Transplantation: Once seedlings are established, the sponges can be easily transferred to larger hydroponic systems or traditional soil, minimizing transplant shock and promoting continued growth

  • Swift delivery
Size: 50pcs sponge
They were perfect and worked so well with my seeds. My plants has sprouted within 3 days of placing them in the soil. The package was delivered quickly which was great because as a garden girly I was too excited to start a new round of plants!

  • Great pods.
Size: 50pcs sponge
Works great. Seem to be a little more compact than other pods I’ve used in the past but didn’t stop the roots from growing and made transplanting easier.

  • Mold grower
Size: 50pcs sponge
Just grows mold on every single one and kills seedling systematically. Very bad quality. They aren't even the same size. A lot are way too short. Nothing has managed to grow. Waste of money.

  • Happy with these pods
Size: 50pcs sponge
These pods arrived free of damage. These pods fit in our growing system. They perform like the original pods shipped with our hydrogrow system. We have six spots in our hydroponic grow system. We grow our favorite herbs to enhance our recipes. We soaked the pod(s) for 24 hours in freshwater before adding seed and placing the pod in our growing system. We probably only needed a few hours (if that) of soaking time but it was easy to s9oak over night. The soaking water was slightly discolored, which is to be expected. We would have concern if the pod caused the soaking water to be very cloudy such we could not see through the water. The pods fit in the small baskets that came with our growing system. Our kitchen is a bit warm (we are in our summer season), so germination in these *inbloom* pods is occurring fast. We expect a quantity of 50 replacement pods will last us for a very long time with our 6 pod hydro growing system. ... show more

  • They're effective
Size: 50pcs sponge
The material of these inbloom grow sponges appears more dense than the ones I normally use, but they seem to uptake moisture and nutrients just fine. I was concerned that the material would inhibit early root growth, so I tested both sets of sponges at the same time with some lettuce seeds under one system. The seeds in the inbloom sponges began germinating first, but not by a significant margin. The seeds planted in "Brand X" began emerging a day later. 100% germination rate for both brands. Above water, the sprout growth was fairly equal. The roots penetrated all the sponges of Brand X before the roots even broke through the surface of the inbloom sponges more than 2 days later. However, Brand X didn't outperform the inbloom grow sponges by a comfortable lead. The main difference was in the price per unit. The inbloom sponges were a clear winner based on value. ... show more

  • Not good quality
Size: 50pcs sponge
These were not the same quality sponges that I received with my original grow kit. They crumble and fall apart and I have not had a good success rate for growth with these. Will not buy again. Would not recommend.
