i have to babys that are 3 weeks old (goodbagseed)and iam getting ready to top them tomarrow....i was thinking about gettin a 150-watt HPS light for flowering and building a box that is 32" tall and 22"deep36"wide.....would the 150-watt HPS be enought for say 4 lil plants maybe? and advice would be appricated..
if the 4 plants are going to be small i think you could get away with it, thats if you dont mind haveing a small yield. if you have the money i'd say go with a 400 watt HPS
