i started with technaflora in dwc and only problem i had was i followed the recipe for success and burnt the plants. its a good product for the price, but the way i look at the price of nutes is this: i run full line of botanicare pure blend pro and additives and buy them by the gallon, thats 9 different gallons plus pondzyme, and my nute cost from veg to harvest is around $1 per ounce. not a bad return.
