Fox farm is better then mg soil (the better brand at hp,lowes) . I just don't want to pay for fox farm price, I use botanicare pure blend pro grow the whole way which has everything that a good soil would have in concentrate. I have used in-organic fertilizers that yeild more but I am after qualty and plant health. To tell you the truth, this season I am giving mg organic potting soil a run, it is composted bark, peat, chicken litter.
Are you growing inside or out?
