View Instructable »Nice comprehensive project. I would suggest skip the LCD and use the bluetooth. I really like http://appinventor.mit.edu/explore/ for doing Android apps and remote monitor temperature and voltage on other Arduino projects I've done. I've also sprouted plants by a window and used NeoPixels to supplement in the evenings. I'm not sure what spectrum I end up with but generally full R and less G and B. Sounds like I should go full B and half or less G

Pin 2 and 3 are TTL serial. I believe a standard RS232-C cable you can get for USB will damage the inputs. You really need a Arduino Uno to program since it already does the USB to TTL conversion plus the Arduino IDE has all the functions to load the bootloader and program the chip.
Nice build. I've been using the SparkFun ESP8266 for my solar projects. It includes a LiPo charge circuit that works without any programming. It's $2 cheaper that the Adafruit charger board but quite basic. https://www.sparkfun.com/products/13231
