I have grown hydro & aquaponics, dwc, aeroponics, coco, peat, rols etc.. in my 30 yrs growing indoors and out I've come to the simplicity of return. So Rols was the winner for me. I use actual hand selected and screened soil, I then amend it with perlite, vermiculite,castings & lime/gypsum.. then I mix peat moss at about 1/3 and coco at about 1/3. I then go for adding dte organics for nutes & aeration like crab meal, vegan mix meals, fish or reg bone meal, frass, rice hulls etc. I also add zeolite clinoptilolite & ceramic bio rings I've salvaged from used aquarium filtration.. same for the charcoal I mix that with bio char for amendments. I've recycled this mix for over 15 years only adding homemade compost & amendments after a few cycles. It doesn't yield like hydro, but the flavors & terps secondary metabolites etc and simplicity more than make up for yields. Plus my soil is alive, it's living & moving under a scope, fully capable of nurturing a plant itself at 100% 24/7 due to a harmonious plant- active rhizosphere.. just add water, light, an occasional tea or topdress and your good.. no testing ph, ppm, tds etc. guessing what nutes to add at which week at what ppm.. I'm too old for all that, one could say I stopped bottle feeding at a young stage of my growing cultivation history. I do occasional buy liquid mother cultures of certain bacterias & enzymes etc but everything else is dry nutes now.
