Hi
@LouShott! Well NFT does not really differ from any other hydroponic system, so you should plan a 5 to 7 days flush duration. Trichomes will tell you when to start (when they turn from clear to milky) and when to stop (when they turn from milky to amber). You will need to decrease your relative humidity for the last days, in order to maximize terpenes potency and resin production. Hope this will help, keep us up-to-date and enjoy your harvest 👊
