d.i.y drying box

hi ev1 could really do with some input here, i made this box with a pc fan, wired to a power supply on low voltage to slow the fan down to pull air through the box , do you think this will work ok. p.s i need to make a lid yet so it will be dark in there during the drying process.

Your box should work.
If your humidity is high, it may help if you add more inlet holes to increase the airflow.

I did a similar DIY over a year ago, using a cardboard box. I used the warm air coming out of my sealed 1,000w HPS light unit to dry it in two days.
