You know, Im kinda on the fence or haven't made my own decision yet on Synthetic VS true organic soil grows on taste . Some ( I do ) use soil with synthetics so it's not just the case of using soil. It has to be TLO. And Is it an Ole Hippie wise tail ? I can't tell the diff if the synthetic grow is done right. I don't know, just me ? I know TLO is a lot easier then having to feed ( brewing teas all the time kinda suck ) all the time and I think the resin production seems better ? TLO can all so go bad on you if your soil dies for some reason, more so outdoors in big holes.
