<-----<<< is NO pro , but what i would do is go to walmart buy a flou. light , the one that holds 2 , 4 foot bulbs there like $14 and buy to bulbs set it up and now you have a cloneing light and a starter light for seedlings...way less electric than that h.i.d. light ... put the 4 foot light a inch or less to the seedling tops on 24/7 for 1.5 - 2 weeks then put them under the H.I.D. and put the light like a foot away with good air movement I have mine 3 inches from my 400 mh and its not in a cool tube....lol an inch and a half away from my bare bulb it is only warm .... You have to keep fresh cool air comming in your box , and you have to get it sucked out just as fast .....pease
