Ok im using a few stand alone cupboards for my grow - one veg and one flowering... i have a large hole at the bottom and top of each for air to get in and out. The bottom hole is passive and the top hole has ducting from a carbon filter coming out of it - which goes to the floor where my fan sits on the carpet blowing warm air to somewhere safe.
My question is... should i be mounting the fan inside the top of the cupboard rather than outside it and down on the floor to get better ventilation - im guessing im maybe losing a lot of power from the fan as it has to draw air right the way up the ducting and into the filter where it could be mounted closer to give better extraction?
What do you think?
