AWSOME HD would love this, man I can tell your gonna be like 9skis and the rest of us that are kinda new to this... we don't know shit, but when someone says something needs to change, we just do it... The pics kinda far away so I cant tell what difference the mh has made, but man do they look a richer green! Your gonna fine, may I suggest watering with superthrive? A few drops in a gallon should do it. Also, do you have mylar reflecting the light back down? There's gotta be something reflective on her roof.. also next time you stop by the garden store I'd pick up a bag of "alabastar stone chips" and add a layer to the top of your soil.. this will decrease the amount of light being absorbed by things OTHER then plant material. Lookin' good, keep doing what your doing

Peace
