Hey guys im looking for some advice as i'm new to the indoor growing scene, i have just purchased two 1000w Prolight HPS lights with reflectors and have a loft 14ft by 14ft. I've lined the walls with tin foil (dull side out) and intend to grow around 40 plants, will this be enough lighting? I'm also worried about the amount of heat generated and my electric bills! Will i require two fans (one to extract and one to put fresh air in) and should they be running all the time or can i set them on some sort of timer, if so should they run simultaneously or should they come on at staggered times? Sorry guys one more quick question, how long should i wait from germination before exposing the plants to the 1000w bulbs?

I'd really appreciate it if someone could share their expertise with me.

Happy Growing!!!
