so i think i may be losing light thru my fan holes. they arent very big holes. is there a way of stopping this?

Theres not really a good way of stopping this (Assuming this is a PC Case grow), and plus the light escaping isnt going to make a significant effect on your grow. If you really want to keep it from escaping though you can make a small cube made from cardboard to fit the size of your fan. Stick that over it and be sure to either leave on of the sides of the cube open a little bit or poke a bunch of holes in it so the air can still flow through the fan. Also make sure the entire cube is coated in mylar or some kind of reflective material.

only thing I can think of is to construct a light trap

a simple trap would b some sort of 90 deg angle pipe, inside painted black, perhaps pvc, or as mentioned earlier a box type trap

i wouldnt do anything, like said before its not going to have much of an impact if any on your grow. not to mention any kind of trap you put in is gonna slow your airflow down, air flows best in a straight line....

both ideas sound good. i hate when i hear two different things and dont know what to do. i need to get a thermometer to see how much airflow i can lose

how do you keep light from leaking in during the dark period if it leaks out during lights on or is the room your box is in not have lights on in it during the dark period at all??
