THE NPK isn't what makes Rock different, it is the organic inputs that make the difference. There are specific aminos, b-vitamins, organic acids, and Resinator's special ingredient is fermented plant material (certain microbes breaking down specific plants to produce naturally occurring compounds which have a dramatic effect on growth).
Mother nature (in my opinion) knows best, just nudging her along with NPK so the ladies have energy to complete the krebs cycle.
Specifically the difference between bloom and resinator is different aminos, b-vitamins, and the fermented plant material that is in Resinator.
The cost is because the line is super concentrated...If any of you guys have questions, don't hesitate to ask away.
I will post my contact info as long as I get the OK from someone on here, just don't want to step on toes. In the mean time if you guys want to PM with some more questions...feel free.
