thanks very very much

To get true airflow through the enclosure the most effective way would be to put two on one side at the bottom and two on the other side at the top. The bottom ones let cooler air in and the higher ones let warmer air out. That said you need to consider your climate. Can you afford to be letting very much warm air out and still maintain the warmer temps required? I think you mentioned they were adjustable. If you can open and close them that is the most ideal situation. This allows you to adjust them for seasons depending on the outside temps. That being said, if you are set on putting the vents in the back they will still work in letting air in and out giving you a fresh air supply. If they are all on the back just do two up and two down. The air exchange just won't be as effective with this setup although it would certainly be sufficient.

I just reread you post. If you use the larger vents on the sides one one each side would be plenty. To make them adjustable you can use 1/4" material in a slot that allows it to slide over the vent. That way you can adjust it according to the cage temps. You may also want to consider using dimmer switches on your lighting as that will help you adjust temps up or down also.

lmao..im just back from hardware store with 2 dimmer switches and read your post...lol..so im thinking along the right lines...when you say larger vents im guessing you mean the square ones..which are adjustable....as opposed to the circular ones that let in loads of air...and if i read your message right..i should put one vent on side say 8 inches on floor....and the other vent other side at top????????hope this is right as i will be drilling pretty soon...trhanks
