Hydroponic sponges are also called soilless cultivation sponges, which are divided into two shapes according to different uses: square seedling sponge and round planting sponge.

The shape of the square seedling cotton is concave hole on the front side and cross-shaped knife edge on the back side, which is convenient for the seeds to take root and germinate in the hole, and the roots can penetrate the sponge to grow; When the seeds grow into seedlings, they can be torn off one by one and easily transplanted into the equipment. Round planting cotton is transplanted after the seed grows into a seedling, the height is unified 3 cm, the diameter is made according to different purposes of the corresponding stock, the side opening design is convenient to clamp without hurting the seedling, and can play a fixed role in the equipment.

Sponges are soft and elastic, moisture-absorbing and breathable, and do not damage leaves or roots; Sponge density can be compressed delivery, compression packaging volume is small, does not take up space, compression time is long, open a rebound can continue to use; Compared with traditional planting substrate, sponge seedling rearing is cleaner, faster, less time and labor.

Sponge source factory, sufficient supply, complete equipment, abundant talent. High production capacity, large quantities of stock, high sponge density, can be compressed for a long time, not easy to deformation. The sponge is environmentally friendly and non-toxic without powder, has SGS environmental protection certificate, and the product quality has been recognized by the local Academy of Agricultural Sciences.
