here apla is some diy carbon filter threads, one or two of these just in the room with the plants, not necessarily exausting out if you can't cut holes or anything 'm sure would help with your smell problem. you can cut it to whatever size you need. or you can get ona gel or something too. i personally would harvest when the trichs are 50%amber 50% milky that way you don't miss out on yield and it gives it an equal body/head high. Unless you REALLY want an energetic high and want to miss out on potential yield, flavor, and potency, then go ahead and harvest. yeah if it is all organic there is no need to flush, because there was no dissolved salts, but one week doesn't sound bad just in case.
Oh and thanks jolly, TERPENES is what gives mary her beautiful resins, tastes, and smells. look it up.
