Ask any experienced grower and they'll tell you that stronger roots mean stronger plants, and in the long run, bigger and better yields. Vitalink is a brand with a reputation for delivering the goods, and Root Stim is no exception. It will accelerate root development and strengthen root-zones against adverse conditions and diseases, prompting a positive response in terms of plant growth. It also comes in a concentrated formula that goes a long way, making it one of the most cost-effective solutions out there.
Add Root Stim to your regular feeding regimen at a rate of between 0.5ml and 1.0ml per litre of nutrient solution. You can use Root Stim right the way though the grow and bloom phases, finishing 3 weeks before you harvest.
