hey piff, good to hear from ya again, i'll have to check your grow. i love using the computer power supply to run the small fans, i have 7 running off just this one $13 power supply i got on ebay. it all seems to be working great now. its perfect for these cardboard box grows. i did a whole deal on how to make it work in my other grow thread. and you can get 3 of those fans for around $10. oh, and + rep to ya for stopping by, LoL.
i know man, its great!! they sould be just the right size at 5 weeks to go into flowering and get a couple clones from.
