does anyone have any inxsight on whether i need a certain bulb to hang it vwertically? I borrowed a buddy 4oo MH to maintain my two mothers and when my clones were ready i set them on the ground and made a vertical setup, he seems to think that the bulb cannot be hung vertically and said "if you break it you buy it".... which shows me his true colors now...lol But i neglected to tell him that i have had it hung vertically now for a month and the mothers love it actually...so my question is, are there certain light bulbs you can and cannot hang vertically? i just took off the reflector and hung it...seems to work just fine for mothers...lol
