Microbial 5lt

Microbial is used as a root zone cleaning and conditioning agent. It essentially sterilizes the root zone and nutrient solution making the plant less susceptible to root born diseases.
The active ingredient is a quaternary ammonium compound of <1.0% w/v and should not be used with beneficial bacteria or fungi.
Microbial is non systemic and so can be used safely all the way up to harvest.
It is best used as a preventative treatment at the rate of 1ml per 2 litres of nutrient solution.
