NO, I remember someone posting pics of their 1000w hps on 1 plant. Overkill perhaps but as long as it's properly vented to avoid excess heat your plant will love it!
yup, what he said^. Plants cant get too much light, you are probably gonna have 1 really bomb plant on your hands if you do it right. And yeah, dont let it get too hot but try to have the light as close as possible so your plant can absorb as many lumens as possible.
