Germination sponge, Growth sponge


Agricultural grade growth sponge for seeds germination.

Made from food grade PU, our hydroponics germination sponge is a lightweight, highly absorbent material (absorbs up to 5X its own weight).
The porosity structure also allows sufficient air-gaps & water retention for necessary roots development. In addition, the media is inert, sterile and thus has no effect (neutral) on pH or EC of nutrient solutions.

Each germination sponge is pre-cut with “工“ shape for ease of seeds insertion.
You just need to tear the required amount easily by hand !
Ideal for vegetable, herbs, and smaller plants.
Seeds are inserted into the slits found in the middle of each cube.


For seeds that take > 7 days to germinate, such as some flowers, melons, tomatoes, beans plants, our rockwool will ensure your seeds get the sufficient water for germination, and yet not to wet that cause it to rot before the seeds even got a chance to germinate. For seeds that take < 5 days to germinate, such as veggies & herbs, use our growth sponge instead ! It’s more economical.
