90x60 grow tent lighting

Hi guys,
I posted this question in several forums and nobody could answer me.. I want to setup a 90x60 flowering tent and am now looking for a led light. My first suggestion would be the spiderfarmer sf2000 but here’s the question now:
If I buy a Mars hydro ts1000 (150w) it would be slightly too small but if I added a Mars hydro ts600 (100w) that would give me 250w for less money than the spiderfarmer sf2000 which is only 200w
How does this make sense?
I could use a little help

It doesn't make sense.
Personally, ì would go for the Cider Farmer.
Grow space is 900mm x 600mm = 3ft x 2ft = 6ft2.
30 watts x 6 = 180 watts needed.
Cider Farmer SF 2000 is ~ 200 watts.

Or buy 2 x Mars ts 1000's which would be more expensive!

Save $$$ in the long run and go HLG,just say'in.... I got MH's and SF's. But HLG rocks the house if ya know what im sayin!
