Nuthin fancy for me.. this is pretty representative for my norm of late using CFL and Miracle Grow 'All Purpose' from start to end. Only other thing I have in my bag of tricks is a simple PH litmus test, alcohol and h20.
Miracle Grow? Get's the job done. Cost? I dunno.. I bought a box last year for 6 bucks, I have harvested about a lb and a half/2 lbs since and still have half a box.

I'm not a 'fan'. It's cheap and works and I use it. Had of Jacks or another all purpose been on sale that day I would of bought that instead. Like I said, I am simple and only do this for myself anymore, I don't like to bother with extra stuff and my plants don't seem to mind as long as they are getting their NPK and trace.
