RV Camper Growing

I am growing currently in a Holiday Rambler .. in one of the closets.. its 50" tall , 50" wide, and 20" front to back.. I have currently 2 pots with one plant in one and another in another. Its not a bad size for few plants... But anyway I had a couple of questions... All the seeds the I have planted are all excellent KB seeds...

1. I have a florescent light bulb for I think a 16" ...
What should I put on the walls? ..(currently they are the wooden paneling)I have no air leaks in there...
2. What kind of lighting should be used throughout the growing stages??
3.

If anyone has any other suggestions or tips I would greatly appreciate them ;)

Thank you my fellow stoners !!

I TOO STARTED MY GROWING CAREER IN AN OLD MOTORHOME.

I USED THE FRIDGE FOR MY CLONES.

THE SHOWER FOR MY VEG-ROOM.

THE REAR SLEEPING SECTION FOR MY FLOWER ROOM.

WORKED WEEL, UNTILL I OUTGREW THE AREAS.

I NOW HAVE A GUTTED TRAVEL TRAILER.

WORKS EVEN BETTER.

GOOD LUCK.
