Now don't get me wrong ( ok, feel free) as I am impressed with those who go to the lengths that produce a water-only grow but...
I have more than a full time job and before and after that I have chores at home that are almost another ft job so when I started growing I was happy, after the build, that growing takes so little of my time.
Organic seems like so much more work and worry than what I do. (Promix/Jacks). For that matter, I am almost water-only. I use 1 tablespoon of Jack's Citrus in 6 gallons of water. Did you start in organics? To be honest, if the friend I approached about starting to grow had told me I needed to pick up a dozen diifferent ingredients for my soil I would have been dissuaded.
