Hey guys! These questions will be based on Ventilation. First off, before you guys say so- I have in fact read the "Ventilation FAQ" that is sticky-ed, however I do have a few more questions! NOTE: I built a grow tent based on the size of the box of a standard PC case [EDIT] Will be using a 50 watt LED (Micro grow) [EDIT] Also maybe chucking in a 20 watt CFL if it makes a difference (Have it lying around) 1. From what I gathered from the "Ventilation FAQ", I cam able to use a simple PC fan or my ventilation - which will be attached to a (DIY) carbon filter - am i correct in thinking this? Or will I have to aim for something that can push a little more? 2a. How big should my PASSIVE intake hole be? 2b. If I fuck up on the hole size and make it too big, what will this affect? Just the odor leaks? or the air circulation itself? 2c. Placing some carbon cloth on the intake hole is a good idea right? To keep any cheeky escaping odors in. Thanks in advance. Sorry for some stupid questions!
