Ideally cut the whole plant at the base. Hang upside down in clean, dark space with 50-60% RH and 20 deg celsius with a fan running at med speed for the first day or two then let the fan slow down for another 5-10 days. Not directly blowing on plant of course. Low and slow is what want to aim for. Low rh and temps with a slow dry. When the branches start snapping instead of just bending, snip off the buds, do a final trim and cure in jar at 60% RH for at least 2 weeks. Remember to regularly burp the jars and store in dark place. Dinner is served
