Hey Dutch,

Yeah I'm using a 150 CFM inline fan at the bottom and a passive oulet at the top through a series of bends to control light leak. I'm going to caulk the inside of the entire cabinet so that there isn't any odor or light leak, and decided to use flat white paint instead of mylar on the inside.

Tomorrow is build day, and hope to have it all finished and tested for light leaks, temps, and so forth before I put some freshly sprouted ladies in it tomorrow night....

How are you doing? Having good holidays over there? Wish you the best and will post when finished building!!!!

Happy Christmas and Merry New Year!!!
