wow really? ok then. also, is it even possible to successfully grow a plant by using just a low watt floro bulb? i mean it seems to be working fine for now. i've got a small fan blowing gently on my plant, and i've got foil on the bottom and the sides of my grow space n so far my little plant was able to grow to almost about a foot. will it continue to grow this way well into flowering? or is there some kind of critical period where i have to switch lights?
