Speedgrow® are natural seed starting products made from Basalt based wool. The fibers are held together with a proprietary sugar based binder. This sustainable technology is 100% Natural and environmentally friendly.

The major advantage of Speedgrow is that the roots do not experience any growth resistance and are therefore more resistant to diseases and pests. The plants will also make better use of the available volume.

Speedgrow® products feature an increased conductivity level due to the sugary binder, so nutrients are optional in the first week.
