Thanks to all who gave me some love, I appreciate it greatly.

These are my test plants for my very first grow. So now that I am confident I have done the veg stage ok i am going to cut off some clones from the bottom and then move them to flower. I will have them under a 600w air cooled HPS. they were veg under a 4' 8bulb tek light T5. what is the best way for me to distribute the co2? I have read to put the nozzle behind or in front of a fan but that seems wasteful to me. How about an air line with holes punched in and rapped around the plant I am willing to do what ever is best because a job worth doing is worth doing right, plus I am to damn lazy to have to do it twice

Thanks a bunch
