What are you feeding? Flushing is not necessary unless you want to rinse out any built up salts in the soil.
I grow organic and just skip the last feed.
I don’t worry about 2-3 days darkness but others do.
I just cut the whole plant, trim off any large fan leaves and hang upside down in 60F and 60% until stems start snapping. Then trim and into jars. Or at least this is what I will be doing after trying a bunch of other things recently that do not work lol.
Personally I chop right before the lights turn on. Flushing and a dark period have no peer review studies proving their benefit. There are studies proving that flushing is not needed, even in hydro. But some people still flush and do a period of darkness. I harvest after a normal 12 hour period of darkness as I would in the vegetable garden for the sweetest produce. I haven’t noticed a difference between that and harvesting just before lights off. I really recommend trying different ways and finding what you believe is the best for you.
When I harvest I try to hang the biggest possible sections of the plant that my drying area allows for. This will help slow the drying process down for a better result. I also leave any leaves that aren’t brown or crispy for the same reasoning. I prefer to leave the trimming for when it’s all dry as I find it to be way less work. Hope that helps give you some insight to the harvest process. If you have any questions don’t hesitate to ask.
I actually learned today from that 48hrs darkness doesn’t do anything to the terps and other cannabinoids. If anything, you would want 24 to 48 hrs of light! Before harvest to maximize terps and potency. It’s during the photosynthesis that the terps and trichomes are formed. The plants produce that sucrose and use the energy from photosynthesis to for all the goodies! Thank goodness I found this out. I’m a couple of days or maybe weeks before harvest.
Blunt & SJ, glad you replied. The clear trichomes are from the top of the bud. I really thought I was harvesting today but you two taught me to let the plant speak to me.
No difference in synthetic or organic nutrients as far the plant or flushing is concerned. You you can rinse your media, you CAN NOT flush anything from the plant . . . flushing removes salts from the medium, does not remove anything from the plant itself.
Think about it for a minute . . . roots are one-way except under severe drought conditions, so where do the “flushed” nutrient salts go? Back into the soil? Transpired by the stomata? Vanish into thin air? No, they stay right where they are before the so called flush, the plants just lose access to additional nutrients.
