I'm using 400w super hps with cool tube and blue side reflectors.
Currently no fan or ducting going through the cool tube but, have a single fan flowing over all 4 plants, temps are fine 25-30 degrees, 45-50 percent humidity, in a 1.2x1.2x2m grow tent. Light is 14" away from tallest plant, critical cheese (auto) roughly 17" for the smaller phenotypes,

Img2, Critical cheese (auto) .
img3. ice bomb (phenotype)
img4. White Widow x Big Budd (Phenotype)
but All are showing some signs of heat or light stress/burn?
