400w CMH or MH...small box , too hot??

im growin using 3x 24w cool white in a small place about 3f x 2f ...i went to get a hid light today and i couldnt find HPS so thouht of getting the next best thing ... found a 400w MH but the guy there kept askin why do u need it and idont know wat... bottomline ...he told me it we be hot using it in a small place ....

and one more thing ..instalin it is kinda hard ..i have to get another part so i can plug it in(even he doesnt know how to instal it,,can anyone help me with that??
showing the pix of the light setups maybe??..so i have an idea

i take it you have 3 ft of height and 2 of width i will also guess 2 ft depth, does the light come with a reflector? because that takes space. also you will need a cooltube with that small space with quite a large fan to move the air in the tube. also you would probably have to do a scrog. and i still think temps would get to high so then you would have to run a co2 setup as well. maybe a 250 with some mylar would work better with a cooltube still.

anybody else think there is a way to make it work?

u got the size right KAOSOWNER .....

can i build a cooltube coz i dont think i can find it here ??

i do believe a few people have buit some here but i have not. i will post a link to a thread where i know a guy was talking about it and you can get some advice from him i am sure he will be of more help with that https://www.rollitup.org/grow-room-design-setup/76617-sexyfattops69-dresser-cab-going-completly.html . I know there are others but i cant think of them off top
