The figure above shows the growth index (a measure of plant size) at the end of the vegetative stage. An application rate of 4ml/gal [of the 1X concentration] seems best for vegetative-stage plants (50.1% increase compared to the control).
"In my experience trialing many cannabis nutrient supplements in commercial and research settings, it's been rare to find one that works; especially one that works well enough to make up for the added cost of using it. In our research team's independent, controlled trial using FlaVUH, we identified improvements to plant growth rates and yield that far outweighed the input cost. For those looking to boost their yield and growth rates, FlaVUH can be a great tool."
