I have been doing hydro since ecology in school and love it...my DWC is so much fun...I love the fact that KI had every issue and now have learned how to dial it in better and hopefully get good yields from my crops. Your set-up looks solid...let me know how you like the LED I use HPS for flowering and CFL for Veg would love to see how the LED works out. Heat and energy are always a great idea to adress.
