you all shouldnt make fun of him if u dont know what u are talking about, the way to get the most light to your plants while still flowering is to have a 24 hour 7 day timer and set it up so your plants are at 21 hours 36 minutes of light and 12 hours dark......

your plant will take quite a bit longer to flower but the yeild will be a lot bigger

so u all just got owned and if u dont believe me then look at the page on one of the best grow FAQs ever http://www.drugs-forum.com/growfaq/607.htm
