Oh By The Way... Just a thought from an old man thats been growing for some 35 years both inside and out.. I think some make it way to complicated. Its a weed.. And I've tried Hydro indoor, hydro out door, soil in and out, High tech digital control fully automated grow room using CO2 injection and a machine controler for all the feed water light stuff ( Direct Logic controlers) and have had just as good smoke if I plant a seed in good soil with simple miricle grow nute and a bag of good dirt as any thing I have tried ..and get more also.. So just from an old grower thats pretty much tried everything .. simplify your life ... Enjoy the moments of just watching plants grow and spend less time trying to find that perfect formula .. Plants do better with Less not More.. In an outdoor grow Nutes are way less important than indoor as nature will provide most of the good stuff.. Lifes to short to sweat the little shit... Enjoy every moment as each can only be lived once and can never be relived again...
