Potential grow cab--will this work?* Please advise!

Hi guys

So--quick question.* I found this ikea cabinet on craig's list for $20 ( http://www.ikea.com/us/en/catalog/products/10121761 )The dude lives in my area and I could go pick it up later today.* I know the height is great, and I like the idea of adjustable shelving, because I could attach my lights to the bottom shelf and just raise it as they grow.* It's also already white, so I wouldn't need to paint it, and the back is made from that cheap ass particle-board stuff, so it would be easy to cut holes for ventilation and fans.* My question is this:* is a 15"x15" square just too small for 1-2 plants?* I've got 3 random bagseeds vegging right now, so I'd be lucky to even get 2 healthy females.* I'm worried about light penetration and space later on, but maybe they'll just keep growing vertically if confined horizontally?* I'm doing a very basic CFL grow (first time), and I'm looking to upgrade from my ghetto cardboard box to something a bit more versatile and stable.

Thanks for the feedback, and let me know what you guys think.* I want to know if I should jump on this or keep looking.

anybody???

that space is really small i would go with one plant.

The price is right but, the box is just too small. I built mine at 24X24 and if I had it to do over again I would go 36X36. I can get 2 in mine but it is less than ideal, they are right on top of each other. Just an opinion, good luck.
