New Grower Small enclosed space feasible for small flowering autos using LED?

[G.Leave]

Would a space that's 54" long X 20"wide X 34" high be suitable for flowering autos using an LED setup? The space using X4 4foot T8 fluorescent lights is fine as far as heat goes and photo plants grow great in their veg state.
I am completely new at LED growing. Would heat be an issue for a space this size? Assume plants would be heavily trained to keep a low profile. Assuming it would be feasible how many watts and what light on a budget would you recommend?
thanks for any advice.

It depends on how many plants you want to grow and how much money your talking about.

Sorry I should have specified a little more. I'd be thinking just a couple of trained autos at a time(4-5 I could fill the whole space I bet). This setup is planned for making a bit of seed, growing some different auto strains to try effectiveness on pain throughout the winter months.
So say a $400 budget on lights....I already have exaust fans, timers, power bars, mylar.
