Currently have 5 plants a few weeks away from bloom. New plans have been made to transport them into a new "vegetative stage" box that is being made this weekend.
Once they are in the new box, the currently used box will be torn down and a new "flowering stage" box will be made.
The flowering box will be 3ft x 3ft x 4.5ft and will be using a 250W HPS/MH Cool Tube setup. Once plants are big enough to move to the new box, they will be put on MH for a couple of weeks to fill out as much as possible then will be switched to HPS for 12/12 bloom.
My question is pertaining to ventilation and cooling. The light has a cool tube around it with a 6" exhaust, but I'm unsure of how large a fan is needed to properly cool the light.
Noise plays a large factor in this because I need something quiet. I think I would rather have separate ventilation for my box and light meaning a 6in inline for the cool tube, and another fan as an exhaust for the box itself.
Any advice is well appreciated so I can figure out my best solution for these fans.
Thank you
