Not really initially Dai, compared to the costs of nutes and things. It also depends on how many "extras" you use as well......and we use them ALL; from Liquid Karma to Sweet to Rhizotonic and Cannazym so I think that's what I meant more by "expensive" compared to soil growing.

Was talking to X-C the other day.......didn't realize that FFOF soil was made in Humboldt County. We only pay $13.00 retail a bag for it but I understand the price really jumps on the other side of the country.
