Just when you think you have reached the limit you find "a whole nother' level". Personally, soil was this realization. I grew hydro for years. Constantly calibrating, contemplating additives, sketching over Ph drops/rise. Don't get me wrong, considering automation, there's nothing like a hydro gro. And now with intellidose systems you can walk away for weeks without a rez running dry and the ph swaggering it's way into deficiency land. I do miss the ease of automation and at times in my "career life" I wish I could somehow automate my soil scheme. Any suggestions?
