Hey Fellas I grow with FoxFarm Oceanforest Soil and add around 30% perlite to the Mix thats all for the medium....I use nothing but FoxFarm Nutes as well...(GrowBig, TigerBloom, Bigbloom)....I use aircooled lights so my plants are always nice and cool except for in the summer when temps can reach upper 80's in the Flowering Chamber.....Been using FoxFarm Products for the Past 7 years and Nothing Else.....It works for me so I'm not going to change a thing.....Thank for the Very Kind Words everybody...~ograskal
