i keep my exhaust on 24/7 and only run cO2 when lights are on....
norcalkush Reviewed by norcalkush on . CO2 and FoxFarm Nutes Question I'm writing to ask for some answers from experienced growers only. Can someone please clarify the need for upping nutrients when using CO2? I've read someone here mention that they double their nutrients when using C02. The nutes that will be used are the entire fox farm line including the 3 liquid ferts (grow big, etc) and 3 powder additives (sesame, etc). Experienced experts only please. Thanks. Rating: 5
