Definitely worth a try..The kis pack is just the bulk of my nutrients..I add a few more things that aren't in there, but you don't have to..Various other minerals,2 different types of castings,multiple mykos on top of their microbe catalyst that's already in there, bio char etc..This pack is geared towards photos so thinning it out with extra base medium in my case promix/coco coir is ideal for photos..Carry that along with teas and bow chika wow wow..This pack is used to recycle prior mixes I made as well..The one I have coming though, I'm making a whole new fresh mix out of so it can compost and be ready by the time my current mix is finished with and ready to be recycled.Pretty much an efficient, perpetual back to back system.
