Rockwool Grow Mats

What would happen if you heated up basalt (a naturally occuring volcanic rock) to the point where it becomes liquid and decided to spin it like fairy floss? You would end up with an awesome hydroponic soilless substrate! These rockwool grow mats are exactly that, with the outcome being a super light, and absorbant hydroponic growing substrate that maintains perfect aeration and moisture levels at all stages of plant growth.

Instructions

How to use rockwool grow mats

To use these simply soak them in water for 10 minutes before planting seeds. Scatter the seeds over the surface of the mat and make sure they've all been wet so that they activate. The mat can be partially submerged in water, sprayed regularly, or bottom irrigated with a trickle of water to keep them moist. Note that they don't need much water as they're super absorbent!
