If I add another 400 watts to that,it would jump up to 87.5 wpsf,isn't that too much light ? I'm worried that the 62.5,is too much..?

As long as you can deal with the heat at the top of your plants then more is better. With more light you can use Co2 and the plant will absorbe it even better. Just monitor the heat at the top of your plants with a remote temprature probe so you get a reading with the door closed.

Zandor Reviewed by Zandor on . HPS VS. MH Hello, thought i would start a new thread with a question? Is (MH) absolutely necessary for flowering? :rolleyes: I read that HPS will do the same as (MH) And :eek: if i purchased a MH bulb at the depot and put it in the hps ballast will it work? I don't want to buy it if it doesn't work, or will i have to buy the ballast "just" for MH. Thanks for any advice from anyone. :o Rating: 5
