i dont have pics but in your shoes i would def go with the 600W light. it really shouldnt be that much more money than a 400W and you'll be thankful at harvest timeCan anyone post up some pics of the difference between bud production between a 400W HPS light and a 600W HPS light? debating between the two and want to know if the 600 is worth the extra money...it will be in a 42"x40"x7' tall area...soil grow,decent ventilation...
