They say Stinky Attic is the best here for advice. I have a few questions as well. I have been reading my ass off in these fourms and for some reason I cant seem to understand what all of these numbers and shit means when it comes to lighting. If you guys remember me im the dumbass who put 13 plants in a 2 1/2 gallon pot and thought I was doing something. I killed them all and now I have to start fresh. Im only planning to start with 1 plant tho. Everyone is telling me to use a 400 watt hps bulb. What do you guys think about that?
