Ok. i have a couple of questions.. im going to start growing in a area that is like 3 feet long and 2 feet width. Ive purchesed a 150watt HPS light. This should cover one plant plenty well..correct? another question i have is.. How affective is Mylar? is there any proven fact that it works good and helps reflect light, is it worth the money?. With the 150watt hps light, how much will my electricity bill go up? and a question for my fans, can i have one fan on one side blowing into the plant and another fan on the other side of the plant blowin the air out of the growbox, or does anybody have any tips or information on some good ventalation n fanning. anybody that helps me out, i will give u much appreation
other questions i keep pondering on are. Will i be able 2 sleep in my room with the hps lights on? and how high should i keep the light above the plants, about how many inch's?
What is your height? 150w HPS is plenty good for one plant. Mylar is scientifically proven to reflect more light than white paint, mirrors, foil, and just about every other common surface. I've seen the charts but don't have a handy-dandy reference to them. Whether or not mylar is worth the money is a totally different question. For ventilation you want an exhaust fan that is sealed to the hole to blow out or positioned outside the growbox in the vent line somehow sucking air out of the box. you need intake as well, not necessarily fan-driven, that depends on your situation. I'm not sure about your question if you can sleep -- the box needs to be light-sealed by the time you start flowering if not sooner. If the box isn't sealed then you will really stress your plants and you wil lbe trying to sleep with a very bright light. The light not be too close to the seedllings right as they sprout, but after about a week they will be adjusted to the strength of the light. What you have to worry about is heat burning the plant, so lower the light to the point that you can comfortably keep the back of your hand to the light at the level of the top of the plant. Be sure to raise it as the plant grows -- you might need to raise it daily sometimes. A 150w HPS will use the same amount of electricity as any other 150w bulb, or two 75w bulbs. It depends on your light cycle and kilowatt hour rates, but it will add up to just a few bucks a month.
