indoor, lighting, grow room

I am about to start my room also little smaller then yours!! But I am going with the same light cooltube but has both lights HPS and MH Maybe something you want to look in to. Might save you some $$ and more stuff to buy The MH Light as I uderstand is not needed in until you flower! But it will help give big bud thicker too!! Hope that helps some!! And good luck!

Simultaneous lighting? Running the MH at the same time as the HPS? Is that what you are saying? I am choosing the 400 over the 600 due to electrical and heat issues, so I couldn't do two 400w at the same time...if that is what you are saying. I thought this one was MH/HPS.

Here is the link I meant to post.
