Tenlead growing sponge is an excellent base for seedling root development. The sponge is made of phenolic foam, which is biodegradable and will completely degrade over time without polluting the environment. And it is an ideal for plant nurseries. The growing sponges retain oxygen well, so overwatering is less likely. They never hinder the development of the roots. You can observe the growth of seeds and the development of roots. Seeds germinate rapidly in the plant growing cubes. Many seeds can be cultivated in a small space. It's a great experiment for growers. These are much more convenient than seeds starting from the soil and are ideal for planting enthusiasts and commercial growers.

how to growing Sprouts on sponges
Growing sprouts in a hydroponic sponge is a simple and efficient way to produce fresh and healthy sprouts at home. Hydroponic sponges are made from phenolic foam material that can retain moisture and nutrients, making them perfect for growing sprouts.
1. Soak the growing sponge in water for a few minutes until it is fully saturated. After that, put some sprouting seeds evenly in the holes of Tenlead sponge. You can use a variety of sprouting seeds to create a mix of flavors and textures.
2. Next, place the sponge in a dark, warm location for the first few days to promote germination. Once the sprouts have started to grow, move them to a sunny location to allow them to develop their green color.
3. Within a week or so, you will have fresh and tasty sprouts ready to harvest. Simply cut them off at the base of the cubes and enjoy them in salads, sandwiches, or as a healthy snack. Growing sprouts in a hydroponic sponge is an easy and rewarding way to add fresh greens to your diet.
