The secondary metabolites in Stack encourage increased lateral branching, tighter nodes, faster bud set and increased vigor during transition. Stack gives the plant tools to reach its full genetic potential. 

As a foliar spray, bioavailable micronutrients are quickly absorbed into the plant. Stack is an excellent addition to any feeding protocol. It will not create antagonism when used with other products.
