Place your bulb (1000 HPS) hoodless hanging in the center of the 5 plants and don't rotate. Trim a fourth of the plant from the bottom when you are ready to trigger, and trigger at around 1.5 to 2 feet tall. No clipping. This is a vertical grow and is best used with a half sativa half indica strain so you get that needed stretch. To cool the bulb get one of those cheap fans that can rotate 90 degree's and point it straight up at the bulb. Air cool if needed.
This is the best way to get large, long cola's and efficient yield. Good luck!
Life is like a toilet paper roll, the closer you get to the end the faster it goes.
