I've been rounding up money for my first grow and know that to start off i will need the tent, lights, nutes, fertilizers, ph gear (up/down, tester etc), fans to cool things down. yadda yadda yadda. but what I was really wondering was at around what age do the plants really start to put off a noticable stink that would start lingering out of the enclosed grow space? I know i'll need to get a carbon filter fan sooner or later, but god damn are they expensive. so about how long would I have between planting and the stinkfactor to round up more money for the fan?
