ok so im off to a good start now with my indoor project, four plants growing in a soiless mix of my own in a 2'x2'x5'3'' Secret Jardin grow tent. For lighting im using a SunBlaze 2 foot 8 bulb t5 fixture at 6500k. my plants are now one month old and growing like crazy and looking great, but odor is starting to be pretty bad. im not using any carbon filters or anything yet, what would be a good setup for fans and a filter ?
