Awesome thanks man. Do you know of any soil mixs that are good to go, I'd like to try that out.
Look into Subcool's supersoil recipe, some of the more knowledgeable members on here have their own custom mixes that they may be willing to share. But otherwise I would just go with Subcool's recipe. Then all you'll need to do is water because, as everyone previously stated the plants will do the rest for you

You can get most of the ingredients on Amazon now if you don't have a local hydro store. Be sure to keep in mind that chlorine/chloramine kills the microbes in these soils, so if your water has either (and it likely has chloramine) you're likely gonna need to get some 5 gallon jugs and lug them to and from the machine every few days and supplement with CalMag. General Hydroponics has the safest Calmag as I've heard there's something in some CalMags that also kill microbes or something of that nature.
If you go the supersoil route, follow the instructions to a T. Don't skimp on the base soil, don't skimp on the 31 days, don't skimp on the stirring of the soil, and so forth. If you use the full recipe, you'll get 3 32 gallon trash cans full, or roughly 100 gallons of supersoil. If you use half of the ingredients suggested you'll end up with roughly 50 gallons of supersoil. In terms of how much it costs, you're gonna spend $200 to make the full 100 gallons of it. I spent a little over $100 making 50 gallons of it (4 bags Roots for $60, 1 bag EWC $15, amendments $40-50). Although this seems like a lot, it's not much different than if you'd gone the synthetic route. Again, if you're going this route make sure you do everything the forum said and ask questions if you need! I'm not trying to sound like a dick, I just don't want anyone to waste the time/money I did trying to get organics right!
If a water only soil isn't practical (not enough time to cook it, not enough money/access for materials, etc) then there are other ways to get the organic experience. In my experience, Roots Organic has the best soil mix you can buy from a hydro store. This soil is used as a base for the supersoil so it's pretty good stuff! Just throw your plants into the Roots soil and water only until flower when you start to see deficiencies due to lack of nutes in the soil. When that happens, just brew up a flower tea and re-inoculate your soil every 2 weeks or whenever your girls look like they're hungry!
