So I just did my final flush of 6.5ph water and it's doesn't really have a smell, (smells like wet plant) it smells real good if you touch the plant though.
70° low 80° high temp
39% low 44% high humidity
Ocean forest soil, fox farm nuits
4x4 tent with 6in exhaust fan, 3 small fans inside
300w and 150w mars quantum board led lights
It will only smell if the terpenes are evaporating. The higher the temps, the more terpenes will evaporate. Most will lower the temps towards the end of flower and in drying & curing to conserve terpenes. If you want to smell the terpene profile, squeeze a bud then smell your fingers.
