225W of what? is it total watts like.... 26w, 26w, 42w
or are you adding up the equivalences of the incandescents?
225w total is a lot for one plant... you can do it... nothing wrong with it, there are people who use 400w hps... its just that some people use less watts for 1 plant... i think its up to the individual... how fast they want to grow, set up, 24 hours versus 18 hours light or even 12 hours of light, how big do you want it...
but yeah... let us know if its the total amount of watts or if its the equivalence
