Ferro Substra Cleaner 1L

When inert substrates such as mapito, rock wool and clay pebbles are reused, they can become contaminated due to the growth of plant pathogenic (harmful) bacteria, moulds (such as Pythium, better known as root rot), viruses, slime formation, sedimentation and salt crystallisation.

Substra Cleaner is the solution.  Use Substra Cleaner to rinse your substrates between crops. Substra Cleaner kills all plant pathogenic bacteria, moulds and viruses in substrates. After cleaning a substrate using Substra Cleaner, allow it to rest for 24 hours. Then soak the substrate in a nutrient solution.

Substra Cleaner is made up of hydrogen peroxide (H₂O₂) and breaks down into water (H₂O) and oxygen (O₂) within 24 hours. This is beneficial to young plants, encouraging them to shoot out roots. Substra Cleaner is the ideal solution when it comes to reusing substrates.
