There are 100% organic ways of growing indoors. If that's what your interested in you can Google it to get different organic home mixes. If you don't want to use a lot of different nutes then you should use just a bloom base of some kind. It's the most important, Sensi bloom, bionic bloom, tiger bloom, there's several to choose from. I hope this helps somewhat even tho I didn't really answer your question. Stay Medicated...V
