I tried the tapping thing for the beam..it all sounds the same..yes you can criticize me for not being a 'man' because i'm not into tools..im sure with that train of thought..you'd figure a woman isn't a woman if she can't clean or cook? lol..you watch too much tv!
In the end, i managed to get what i need with pvc pipes and built a frame to hang the light from. I figured i can always add and modify the frame if i need more lights...i'll have sheets of mylar hanging on 3 sides. The heat seems manageable for now with a fan, still freezing temps here. The brightness is impressive..easily blows my '376 true watt' cob and mars 300 combo away! Put 2 auto's and a photo at 2-3 weeks old under them..light at 20 inches from plants. Will be starting alien vs triangle and 4 assed monkey from mephisto this week.
