I need venting in two grow spaces im making. They will be 2x3x6 and 3x3x6 boxes smaller one for vegging and bigger one for flowering.

I dont have money to get the inline fans yet but right now i have two table fans to blow at the plants inside the boxes for each box.
Than i have three 3" pc fans glued to cardboard using as 1 fan and 1 bathroom fan and planning to get 2 or 3 4" or 6" inline duct fans the cheap ones.

Plan is two table fans blowing at the plants inside of each box.

FLOWERING ROOM:
3 PC fans blowing air in from bottom of the box and maybe 1 more inline fan on bottom to bring more air in. bathroom fan on top sucking air OUT with ducting connected down to the floor connected to a homemade carbon filter can. 1 inline duct fan with ducting taped towards the reflector of the 400 watt HPS light SUCKING OR BLOWING? air from light fixture..? Let me know plz!
So thats my thoughts on flowering box.

Vegging box:
table fan blowing inside at plants.
inline duct fan blowing air in bottom of box
inline duct fan sucking air out at top of box. Will use CFL for vegging so heat wont be an issue i think.

Please let me know if my plan will work without a problem. Or if i should add more inline duct fans or whatever reason. Any advice would be nice.
And should i get the 4" or 6" inline duct fans? These are the 20$ ones at HTG supply.

Thanks!

Thanks! I wont make holes on the reflectors but i think taping it near it would help either way.
