hi all, was wondering if any one could help me with my grow. I am currently growing three bubba kush plants in a grow room they are about 5 inchs tall and look very healthy. my grow room is 80 cm x 80cm x 160 cm, im running a 400 w hps lamp and a 4 inch fan for air flow. i am watering them every other day and growth is coming on quite quick. My hope is to finish my grow with my plants around 3 feet tall and i was wondering what hight the plants should be when i change the lighting schuedual to 12 on 12 off for me to achive around the desired hieght. thank you in advance.
