ABSOLUTELY! Our nutrients work great in all growing environments and will work great with the Fox Farm soil you're currently using. All of our products have added benefits but mainly you would want to use either our Basic 3 part system which consists of Base, Bloom and Grow or you could go with our Advanced 5 part system which includes Base, Bloom, Grow, CalMag and Shock & Awe Bloom Booster. We also offer Atomic Root Powder and Bio Minerals as additional supplements.
