what up,
well first off u meight need more light, i dont know if halogen is incondescent but if it is it wont do shit fer ur plants, also floros dont giv off much heat if any so they can be pretty close to ur plants w/o burning them. and u said u put them under light fer an hour during dark period i think and ive always been told that interupting the dark period is bad but im not 100% sure on that. anyway good luck and hope u get some bomby weed.

peace
