Hey, me too on the back pain. Was in an accident, spinal injury, neck, lower back & broke 3 ribs loose from my spine, mid back. Lots of nerve damage. Have insomnia too, so I smoke to sleep at night. Don't get me wrong. I've always been a pot head, but now I need it. Have several health issues that would also qualify me for mmj too, arthritis, etc, but back & sleep are #1.
-- I really like my T5's. I have a 400watt hps somewhere in a box in the attic. Overkill for my closet. But I may just stick with T5's in a SOG. Indoors is secondary to my outdoor grow, so its quality over quanity here too. My entire outdoor crop was ripped this past summer though.
