well if you are only going to veg and not flower then what your doing is ok I would change the time to 18 hrs on and 6 hrs off. the plants might begin to flower or stress with the time you got now. or you can just leave the light on 24 hrs. b

If you do deside to flower then i suggest you get a HPS system. I can help you find the best deals especially if you got a set income and can not afford the real expensive systems like I can't. let me know email me and I am also trying to get a patient growers group so we can come together to help each other. if interested hit me up n email its in my personal info:smokin:
