Damn dude things are really moving along nicely. I think your development may actually be slightly ahead of mine (I think you stated 12/12 just before I did? I started Nov.30th) Anyway those T5s are impressive. Tonight I'm going to install bank of 4x4' T5s perpendicular to my HPS box to get some wider coverage and side-lighting. Another advantage of your shorter plants is that the stems aren't falling over. Mine are so long that now that they're putting on weight they're flopping all over the place. With all of my tethers it looks like some kind of weird S&M session going on in there.
