look up Terraponics and see it has nearly all the mediums used mixed together!, including coco and vermiculite as well as the above, try and make your soil medium as soil free as possible , while leaving the good properties of soil in there the other mediums will allow for good drainage and oxygen retention.
hey give it a go if ya wanna experiment ,
but ya may concider uasing a varieing mix in each pot, labeling them, and keeping a record of the mix for when the crop is done, so you can duplicate the "right " one again, for the following crops!
alternativly, spend some money and either go hydro!, or buy the Terraponics from the net!. at least check it out on the net for its ingreidients, and properties!,,,,,its actually called terraponics, and the web page is www.terraponicseurope.com it contains 23 propritary ingredients, including three soils ,leonardite, humic and vulvic acids humic peat,organic rock, volcanic rock. vermiculite and perlite, etc etc etc

check out there web page!

welcome to the world of endless posibilitoes,,,,,hydroponics!
mistyganjatree Reviewed by mistyganjatree on . Soil grow with hydroponic dripper. I know hydroponics is without soil, but I use soil. If I have a drip system at the base of the plant roots for a 1.25mx1.25m soilbed with 20 plants SoG. With a drainage at the bottom of the soil bed leads back down to the resevoir. Is this a workable system or any forseen problems? I would need a resevoir, pump, filter and 20 drippers... anything else? Rating: 5
