Hello stoned 88911.. I use FoxFarm OceanForrest and have been for years... You can use it straight with great results, I have many times... But I do like to lighten it up... I use FF Light Warrior because of the Humic Acid and Mycorrizal Fungi... But I would add 3 or 4 nice handfuls of perlite to a 3 gallon pot.. Im sorry I dont do exact measurements I go by feel... Just go for it... OF has a lot of goodness in it just dont have perlite floating on top.... You could do a 5 to 1 ratio safely and get good results... d:rastasmoke:
