Hello gc I have done 2.5 grows now all using bottle ferts but I think it's time to make the switch. I google some recipes and I'm going to go with sub cools super soil. Here is the list of ingredients. 8- Large bags of High quality Organic potting soil with a coco and Mycorrhizae 1- 25-50 pounds of Organic Worm castings 5 lb. Steamed Bone meal 5 lb. Bloom bat Guano 5 lb. Blood meal 3 lb. Rock Phoshate ¾ cup Epson salts ½ to 1 Cup cup Sweet Lime ( Dolimite) ½ Cup Azomite ( Trace Elements) 2 tbs. Powdered Humic Acid I can get all the stuff as we have a very good local hardware store that sells most of the stuff and we also have a hydroponics store for anything else I need. I started all my plants in happy frog and been using roots organic bottles on them. I must say they are looking very healthy but in the long run I feel super soil will be better. My questions. This super soil good for veg/flower? Could I still use my bottle nutes? Instead of once a week maybe cut it to once a month as a tea? What do you think of this mix? And lastly how much soil is this going to make? Can I convert pounds to gallons?
