starting to grow 2 plants, grow room is 5'w x 6't x 30"d. wondering what might be the best lighting set up to go with. any input helps. thx
 
Ten 5gal buckets will fit and two 400w's will light it perfectly. 400's only support up to 2.5' of vertical plant growth so you'd want to have them at or below that size at harvest, or else get stronger lights.
 
you could go with a 90w led its equal to a 400w mh for that area easy, they run about $150 and you dont have to deal with heat or a ballast.

so would one 400w work if i was to do 3-4 plants or should it still be two 400ws?

We always put 4 plants in 5gal buckets underneath a 400w HPS. So, yeah. With a strong yielding strain and sufficient training, up to a pound can be had at each harvest using one of those.
 
If you were to do 4 sativa dominant plants in a grow tent, what would be the optimal size a dude can use plannin on getting a secret jardin dr tent with a 400w lumatek
