I got an idea for a vert grow with two cooltubes.. no reflectors, put together, top bulb pointing down bottom bulb pointing up, bottom bulb MH top bulb HPS, 400 600 watt respectively. Run the bottom through the whole cycle. 18/6 veg 12/12 flower, top only 12/12 , start to flower when they reach the top of the bottom cooltube
