Advanced makes thier nutrients for growing our favorite plant. The research they do for thier products is geared toward Cannabis cultivation. One of the founders is a licensed MMJ patient. Some of thier new stuff will only be available from a MMJ dispensary. They are expensive as all hell but they also offer a money back guarantee on all of thier products. If you haven't heard of Remo "Urbangrower" check him out on youtube or at urbangrower.com. I will be opening a dispensary in a few weeks and plan on offering thier products to my patients who grow thier own. As well as other brands.
