1x Mars Hydro II 900w or 2x Mars Hydro II 400w?

Can you even fit 2x 400watts beside each other in a 3x3?

You're working with 9 sq ft of area. HID and older tech diodes like those used in Mars and other 'blurple' fixtures need approximately 50w/ sq ft to provide optimum light levels. You will need 400-450w of actual power consumption-the '400's' run about 150w/fixture and the '900' is about 350w.
You won't know how much you're leaving on the table until you step up to better components.

I have read the kind LED's are worth the cost...any truth to that?

Nice info, thanks.
I understand the Mars II's are lower end, for me its about cost atm, I do plan on getting better equipment over time, what would you recommend? I have read the kind LED's are worth the cost...any truth to that?

New to using LED lights and have been using a mars hydro II 400w in a small tent (3x3), I want to ensure I am getting the best possible light distribution within that small area. The mars 400w is suggested for a 2.5 x 2.5 space but that dwindles down to 2x2 for flowering.

My question is...would it be more efficient (better) to use a Mars Hydro II 900w or buy another 400w and daisy chain them? I am currently growing 2x Jack Herer in the space, was going to try for 4 but assumed and rightfully so...that a 3x3 would not be enough space.

Couple pics of them attached...veg phase.
