good info but i wana be exact on this one. so i have a 44 inch grow space from top to bottom. the light only takes up about 3 of those 44 at the top. the light is a 100 watt hps. my biggest plant is about 15 inches tall (including the pot). the actual plant is only about 11 inches. i want to know about how tall i should let the plant grow before i put it into flower. below is a pick of the space. keep in mind that the shelf the plants are currently sitting on can be removed.
