I would drop to 18/6 or atleast 20/4when you go to the new light. That is a great improvment in lighting. You will be happy you got the light. That light will burn hotter so be careful and watch temps....
bobjob4u Reviewed by bobjob4u on . Changing Lighting I am gettting ready to change from 4 23watt cfls to 400 or 600 mh/hps combo by next week. My plants are around 17 days old right now and i was wondering if it would be too stressful for them. I am running light 24/7 right now. Any input would be greatly appreciated. Rating: 5
