NFG wants to know

I had 2 7x7 rooms 1 with a 1000w MH for veg the other 1000w HPS for flower. I just made another 7x7 room for flower also. My question for all is ? I will now have to buy another light set up should i get another MH or HPS for the 2nd flower room

You questions worded strange, thats why no ones replied yet. So Im assuming you had 2 rooms and your only using 1 at the moment and your about to have access to the 2nd? If so just have the 1 MH that you already have an invest in another HPS, that way you can have clones/babies/seedlings in the veg, medium sizes in the first HPS and the late flowering ones in the 2nd HPS room.

I'm guessing that you are breaking the bloom room into two stages so you can have a perpetual grow? If that's the case, another HPS would be the obvious decision, BUT, I've always wanted to try a MH for the first half of bloom, and see how much it reduces stretching, so IDK. Either will work great, but keep that in mind when you make your decision.
