Size of hydroponic grow room

Hi, everybody. I'm planning to start my first hydroponic growing, but first I have to set up a suitable grow room.

My house isn't so big, so we are talking more about a grow closet than a grow room.

Here's the question: the size of my closet is 18x18 inches (4 feet tall). Is it too small?

Thanks for you help,

Diego

nope you can do a rubbermaid bubbler.

idk the minimum just put a rubbermaid in there and see if it fits.
Are you doing cfls or HPS?

Sorry, what exactly is a rubbermaid? (I'm quite new at this, just starting.)

somethin like this

Ok, but this thing where do you get it? Or you can make it somehow? Is there any "Hydroponics for dummies" out there?

yea there are plenty DIY guides on here.
