You know, halogen lights are the culpritz,,lol.. im certain, i didnt see those pics yesterday of your indoor setup and the halogen lights , I have used them in a pinch, when im short on hps bulbs or i need to raise the temps more in a room, but they are very hot lights and will accomplish several things when used, increase your electric bill threefold, lower humidity, raise temps and with the clear covers removed crisp up the edges of leaves quite nicely. think toaster oven with photons. and the 500 watts will quite literally catch things on fire. but they do kick out some light and sort of in the range of color your looking for at this stage of the game. use with caution and the way you have your plants arranged within the room matters, the plants that have been closest to the light for the longest time will withstand more than the others , simple conditioning, if you place the plants willy nilly and don't put them back in order you can toast a plant that normally would be farther away from the lights. Just a few lessons that i have learned through the years.
