ok bit of a tweak happened. Here are the new materials being used. pretty much same as old lol.

switched out the other fan and got a combo:

1 x 6" Carbon Filter
1 x 6" Inline Fan (340cfm)
1 x 6" x 30 Feet Aluminum Duct Tubing

also different reflector. was cheaper and gave me 2 extra bulbs and little accessories.

I believe the tent comes with a bottom hole and obviously top holes cause i can see them in the pic heh but how do you block the light from entering if you leave the holes open? I'll definitely get a desk fan to help cool and strengthen plants.

if i did need a 2nd inline fan for exhaust would a 4' do? i found a 4 Inch Inline Exhaust Fan Blower 210cfm (last pic) for $80

appreciate the help imp:
