hello,first strains are good but the haze might be a bit fussy for a first time grower i would do the northern lights its easy to grow and a big yeilder,your grow box sounds cool in that space i would use a 600 mh then change bulb to a hps(son-t)hydo set up is good nutes are ok buti would use canna hydro flores a+b with pk 13-14 as a bud boost,carbon dixide any natural burning gas will do i use a single ring camping burner works wouders,i dont pinc i bend my tops over and tie them in place,1 5" rvk fan for your outgoing and a 4" intake fan will do,and get a 5" carbon filter to kills the smell.good luck all sounds very cool:thumbsup::thumbsup::thumbsup:
