my two cents... i have been growing a couple years and have tried a lot of organic based nutes, and after finding dutch masters product, I could not be happier. It's pretty much clear, alittle go's a long way, and it will pretty much p h balance itself. It should cost less than a $100 to get set up. I use the one flower rather than the 2 part mixes, its just eaiser for me, I am far from a pro. hope this helps.
