air intake question..

Here is a picture of my growing space, its about 40x60x200cm.

Im gonna put an ufo fan to blow hot air out and i was just wondering is the air circulation going to work ok if i place my air intake to roof with some hose to lead it to the bottom?

How better ventilation would it be if i just drill a hole to bottom? It would be much easier the way i have planning to do.

Please help me

the more ducting you have, the harder it is for the fan to move air .... ideally, pull fresh air from the bottom (short ducting), hot/exhausted air out the top. shorter the ducting the better ... 90 degree bends in ducting help prevent light from leaking in/out of the box if needed

yeah i know some basics but it is just that much easier to make stealth ventilation from roof. But if its gonna be like ten times better to make it from bottom then i quess i just have to go for it.

if its a cabinet then you could have a raised floor and pull the air up through a number of holes in it. put a skirting round the front and sides and let the back be a passive intake.
