Will This Closet without a door work

[klh528]

This closet is 6 feet tall and I'm growing one plant under a 2x2 sf1000. I'm assuming if I completely cover all the walls with reflective material except the opening, I will still have enough light on the plant?

Make a door
Don't forget about intake and exhaust

When you flower you’ll want a way to keep dark

I’m a Carpenter. That looks like a 2-4 (measure it ), right hand door.
