Looks really good. Thanks for replying to my comment on your other post to let me know that you wrote this one. We don't have great windows to put plants in because of the way our house is situated but have several raised beds in the back yard. Once my wife has finished using the grow lights to get this years seedlings up, I'm going to be starting hydraponics using the Kratky method. I figure I've got a month to get it all figured out.
