Oh and you asked if my T12s were horizontal or vertical, they're vertical. I started the grow with the plant in the corner of my closet and the T12 leaned up against the wall at an angle kind of.

Now that I have the grow tent and the CFLs the tubes are vertical and are great for side lighting and even hits the top buds too. They never get hot so you can just stuff branches into the lights and they're as close as physically possible heh
