How To Know When To Harvest

You can check to see if the trichomes are dead-heading (my term) loosing the head/bulb of the trichome, you can check for spider mites that can infest you plants in the later stages of flowering, you can't see them with your eyes but you can see their webs, yuk.
 
The essential facts of timing your harvest

You've managed to make it to the end. You've maintained your plants well, now it's getting closer to harvest time, and you're wondering just how and when to harvest and dry those beautiful buds. Hopefully I can give you some insight into how this can be successfully done; the do's and dont's of proper harvesting and curing. First, lets take a look at the harvest side of things.

Timing of your harvest is critical! Harvesting at maximum ripeness is the key. In my experience, there is usually a five to seven day window when the Cannabis plant will be at maximum ripeness. To understand this, you will need a jeweler’s loupe, or magnifying lens, light optional. I would recommend a power of 30x or better, but you can get by with less. A greater magnification makes it much easier to see the trichome heads at the top of the stalked resin glands.

Resin gland color, potency, and type of high

Gland color will vary with ripeness of the individual THC glands, starting at clear, turning to milky, then turning to an amber color. There may be some exceptions, such as some of the Blue strains and Blackberry. These will have darker, sometimes purple gland heads. But by far and large, these three steps of ripeness will exist with the vast majority of strains on the market. The first stage, clear, will tend to make for a more cerebral, up high, with very little body effect. Harvesting at this stage when little if any trichomes are milky yet, can be tricky. Harvesting too early can make for a beautiful plant that will not have much psychoactive capability! THC needs to "mature" to be able to pass its psychoactive capabilities down to the smoker. This is why I always recommend waiting until 50% of the trichomes hit the second stage: milky or creamy. At this point, you will definitely have a plant which has reached its genetic potential.

The milky trichomes have some "cerebral" qualities, as well as some of the more "physical" characteristics of the high. The last stage, amber, brings on a more sedative, physical stone. If this is what you're looking for, than I would recommend a sativa/indica cross, or an indica dominant plant. Amber trichomes seem to ruin a sativa high if the plant goes too long. The below photo is a good example of a ripe plant: at least 50% of the gland heads have turned "milky," some heads are still clear, and a few are amber. This plant was harvested two days later.

Many times you'll read from new growers, "My hairs are 50% changed to brown or red, looks like its ready to come down." Calyx hairs turning color is one thing, calyx hairs withering, is another. When they have withered, they are for the most part, as ripe as they will get. But just turning red/brown does not necessarily mean the plant is ready. Calyx hairs are just an indicator that the plant is ripening, not necessarily ripe yet. I have taken full Indica strains with 60% hairs turned, and sativas when 90% hairs have turned, and they were all at peak ripeness. The trichome color is the only true indicator!

what would you say?

I'd say, "Make sure you are inspecting the heads of the trichomes on the buds, not the ones on the leaves." And to harvest when you feel that there are the maximum number of cloudy/milky trichome heads - even though that means you'll have a small number that have already degraded to amber and a few immature ones that are still clear, because they don't all mature at the same time. If you've been observing for a while, you noticed that the clear ones were turning milky at a faster rate than milky ones were going amber. At some point, that'll no longer be the case, and you'll see more degrading than you see maturing. That's "diminishing returns," and you should have harvested just before that point, lol. Maximum potency time.

And, yes, the above can be done on a "per bud" basis. You might find that not all of your plant is ready for harvest at the same time, for various reasons.
 
I agree, check the buds to see the condition/color of your trichomes, I go for mostly cloudy trichomes too much amber and its serious couch lock for me. Mostly cloudy gives me a nice high and easies my arthritis and I'm still sharp, kinda :Namaste:

This is only my second harvest and I feel like I am always second guessing my timing, like I I right now....

I generally pick them early because I like the uplifting effects. Sometimes I will pick a bud off the plant a little early and test. Great article.
 
Can lunar phases be used to determine the best time to harvest cannabis, and how might this affect its quality?
There are many indoor and outdoor gardeners who follow the phases of the moon as a way to determine when to plant seeds.

Then there is the harvest moon, usually in late September in the northern hemisphere, which got its name because of the extra light into early evening which makes it easier to harvest crops. It is not necessarily a way to know when it is the best time to harvest any crop.

Up to the gardener to figure out how mature the crop is and when it should be harvested. An outdoor gardener will have to take into account not only how ripe or ready the plants are but what the weather is going to be.
