Hey , I saw your comment about how some people get arrogant and what not and agree wholeheartedly. I go mainly to Green Passion.org, great place and while there are a few know it all's they are great people . I think you where asking about using Actinic bluelight and I use tthem with high noon terrarium bulbs with amazing results. Good luck. Go with your gut feelings, trust your instincts..take care..
