Primer B

Rooted Leaf Agritech Primer B is Part B of Rooted Leaf's two-part base nutrient system, providing the phosphorus, potassium, and complementary mineral compounds that complete the nutrient solution when combined with Primer A. Part B delivers the macro elements separated from Part A's calcium and nitrogen compounds to prevent mineral precipitation in concentrated storage.

Together, Primer A and B create a complete, balanced base nutrient solution for cannabis from seedling through harvest — with ratio adjustments between vegetative and flowering phases per Rooted Leaf's feeding chart.

Add separately from Primer A when building the nutrient solution. Made by Rooted Leaf Agritech.
