I started started with an aero machine and 2 years later I still am working out all the details. I have tried nearly every other type of cultivation and have to say that aero is the most efficient. I do use soil for moms though because of the ease and reliability. Thats all I was wondering about the UV sterilizer. If it will kill the good stuff and bad stuff all the same. I think I will stick with my benificials and not use the sterilizer. But some day I might run a comparison bucause that would cut down on operating costs and wasted time of adding the various bennificials, a UV sterilizer uses a nominal amount of power.
Thanks for the info!
