Hello uberbud, I did use TECHAFLORA 3 part and now I use GH 3part and till I finish my cab I'am still in soil.When using in soil I cut the nutes in half and slowly up the nutes.Hydro nutes and soil together puts alot of nutes in the mix.The plants get nutes from the soil and the what you add in the mix.I water them 4 or 5 times before watering with the nutes mix.Peace
