hi guys...first off...he doesnt need a hps light to grow....nice grow or small grow....matter of fact....he will have a better control over his environment with the flour. light.....less heat....but with that said.....read some...i spent over 12 hours of reading the forum before i started to ask questions.....and dont listen to those who say you need a certain light...what you have is fine.....unless it is the equivilent to 100w....then you need to buy a couple more.....and if you are the one growing in the 2 foot area....DONT GROW...a rookie cant control his plants without killing them....unless you really take good care and control your plant's height....which you can....by keeping your Flourecent light close to your plant...maybe 1-3 inches away from the top.....but hey...experiment a little.....enjoy your grow
