/diy/ - Do It Yourself

First time posting here, had no luck anywhere else and google isnt being kind to me as a first time user.
Currently based in the Uk

Say if I wanted to grow a plant within a wardrobe, and that plant required an extractor and a 200w light within the wardrobe as well that is running 24/7.

1) What are the chances of a fire if set up properly?
2) Is it possible to just buy a cheap wardrobe from Ikea and then cut holes for potential extract fans and intake fans?
3) if intake fan is at the bottom, will it become clogged with dust from carpet?

Thanks guys
