You will need very good airflow , fans running 24/7 & some type of ventillation.
My growroom ran for about 8 months , humidity over 90% @ times & no mold or algae.You could cover the walls with Mylar(exceptionally good reflective material) which is plastic & should protect the walls.
Light wise you,ll probably need a HPS or metal halide setup(or the new ceramic metal halide which gives full spectrum light) but these give off a lot of heat.
If you need more details just post up .
