Yet another How Long Until It's Ready To Harvest question

[CrazyChef]

So I was taking some close up pics of the girls, and discovered that the sugar leaves already have about 50% amber trichomes - I wasn't expecting to see any at all. But the buds, from what I can see, barely have any milky ones at all. So, how long would you estimate until they're ready to chop? Right now, they're at day 43 since the flip to 12/12. I'm thinking maybe three weeks, but this is still my very first grow and I'm very interested in the opinions of our more experienced growers here. Thanks!

CURRENT JOURNALS:

By the white hairs... awhile yet

But those pics really don't show diddly if they are close or not

Never judge trics on sugar leaves, they degrade wayyyyyy faster

 

[Carcass]

The trichomes in the second (bud) pic look mostly translucent (milky) to me,so now you just wait till your chosen percentage of them amber up- I chop at an estimated 10%,but some folks wait for a little more-it's up to you...
Couple more weeks would be my guess...those are some fat trichomes on that girl!

 

[The Bard]

Still pretty new to judging this myself, but I did learn to just ignore the sugar leaves completely. I did my first chop at 70% cloudy/20% amber and just a few clear, as that was for sleepy meds. The last plants I did 90-100% cloudy, a few clear, no amber, as that was for more fun/upbeat. Like others have mentioned, I'd guess at least two weeks, perhaps more depending on how mellow you want it to turn out.

Nice frosting!

Harvesting Marijuana! When To Harvest Your Marijuana Crop
By DJ Short
There are several important points to consider when choosing the optimum time to harvest your marijuana crop. There are different factors to consider between indoor and outdoor marijuana plants. There is the difference between Sativas and Indicas in bloom duration and final effect.
There is the difference between early and late harvest to encourage head to body high respectively. There is the issue of chemistry because what we are really considering in terms of the ripeness relates directly to the chemical nature and state of the plant at harvest. Last, but not least, is the concept of the window for marijuana harvest, where I will begin.

Window For Harvesting Your Marijuana Crop
This term indicates the period during which the plant is at its optimum state of ripeness. The window opens when the plant is first ripe. Somewhere along the line the plant becomes over-ripe which signifies the closing of the window of harvest.
For most Indicas grown indoors, the window of harvest is about two weeks long give or take a couple of days for various strains. Indoors, if going directly from an 18/6 hour vegetative light cycle to a 12/12 hour bud cycle, most indicas take about eight weeks to fully mature.
As to outdoors I can only speak from experience at the 45th parallel and the bloom times there. At the 45th parallel I've found most Indicas to be at peak harvest starting at the beginning of October, sometimes very late September, and running until the end of October, sometimes running into November during mild years or in a greenhouse. My favorite time to harvest a nice Blueberry Indica outdoors is in the second to third week of October.
For Sativa grown either indoors or outdoors, the window may be open much longer. Some Sativas take up to thirteen weeks to mature indoors. Outdoors many will go well into November and even December, if conditions are right (again, this is near or at the 45th parallel). Head High or Body Stone?
An important consideration has to do with one's preference for a head high or more of a body high. A good head high can positively influence one's mental state much like a psychedelic; whereas a good body high is more similar to a narcotic effect. Generally, head highs tend to be more up and body highs tend to be more down. Suffice it to say that a good healthy mix of the two is a fine goal to achieve.
Sativas and early window harvests tend to be more of a head high, whereas Indicas and late window harvests tend to be more of a body high. Given this rule of thumb you can pretty much come up with what you want. That is, if you prefer a very psychedelic head high, then an early harvested Sativa might do best.
If a very narcotic body high is desired, then a late harvest indicas would probably do best. For that best-of-both worlds high, experimentation with late harvested sativas and early-to-mid harvested indicas usually proves interesting.

Magnify Your Buds
When we speak of various highs experienced by different products, we are noting variations in plant chemistry. The chemicals we enjoy are produced within the glandular stalked trichomes, along the surfaces of the bud flowers (calyxes), bracts, leaves and stems, starting in or around the fourth week of the bud cycle. More and more of these trichomes develop as the plant matures.
I highly recommend that the serious cannabis student acquire a 30X power, illuminated magnifier. These can be found at most local electronics stores, often for under fifteen dollars. With the aid of the magnifier one can learn more about the detail of trichome development and ripeness.
As far as trichomes are concerned, the tall ones with swollen, clear, bulbous heads are what to shoot for. The denser the concentration, the greater the potency.

The Cycle Of Marijuana Plant Maturity
Starting in the third or fourth week of the flowering light cycle, glandular stalked trichomes will begin to form along the surfaces of leaves, flowers, bracts and stems. At the same time, more and more flowers (also called calyxes) develop into densely-packed floral clusters.
The pistils of the young flowers are bright white and turn reddish brown with age. The pistils and flowers develop from the bottom of the bud to the top. The older, lower pistils are the first to turn reddish brown. For most basic indicas this usually happens by the sixth week in the flowering cycle. It is about this time that the calyxes begin to swell.
Calyx swelling is a major indicator of peak maturity. The lowest, oldest calyxes swell first and the swelling works its way up to the highest, youngest flowers on each bud. At peak maturity about 90% of the calyxes will almost look seeded, they are so fat.
Three quarters to 90% of the pistils will have turned reddish brown as well. For a basic Indica this takes well into the seventh week of the flowering cycle.
By the end of the eighth week most of the calyxes will have swollen and a surge of trichome development has coated most of the buds. It is now that the development of a very discerning palate comes into play to determine the finest harvest time. Remember - patience is a virtue and often a discipline.
The ripening signs for most Sativas are highly similar, except extended over a longer period of time. Occasionally, some Sativas have windows of peak harvest that actually open and close. That is, for a week or so the plant may exhibit signs of peak ripeness.
However, a week later the plant may have a growth spurt, which lowers the trichome-to-fibre ratio and overall potency for a little while. Usually a fibrous growth spurt is accompanied by a corresponding trichome increase. Again, time and experience are the key elements in this regard.

Changes In Marijuana Chemistry
As the plant matures through its window of harvest its chemistry changes. As the window closes, the more desirable compounds begin breaking down into less desirable ones. Primarily it is THC breaking down in CBNs and CBDs.
Which particular combination of chemicals is the most desirable is purely a matter of taste and choice, developed over time and with experience. Set and setting also play an important role in determining which type of product is best appreciated.
Pleasant head highs are often desirable for social occasions, whereas a narcotic late-window Indica may work better as an evening medicinal herb. The main point is that these differences are chemical in nature and more research is needed to more fully understand this phenomenon.
Another important point is that much can be done to further enhance the chemical process, especially in regard to bouquet, aroma and flavour, given the proper curing process.

I read this recently - great minds think alike!

What I was considering, and I think you've helped me to make up my mind, is to harvest one when it just barely starts to show amber trichomes on the buds (=/<5%), then harvest the other at about 70% trichomes. The two plants are mother and clone. This way, I can get a relatively unbiased comparison between the two harvest types. So, I guess harvest the first one that shows just a few amber trichomes, then let the other go to about 70% amber.

Will be a cool comparison.

The only reason I wasn't sure if I wanted to do it or not was because I would lose a bit of yield from the one that will be harvested at =/<5% amber. Here's a couple pics of the 2 girls:

Good work dood. They look great so far!

 

[zeroday]

This is very timely. I have three different grows harvesting in the next 30 days, so I'll have the scope out like crazy, racking my brain trying to decide when to chop.

I swear, when I finally do chop them, I kinda of just blank out my mind and stop thinking all together, grab the choppers and do it. Its a brutal decision sometimes. So subjective.

 

[CrazyChef]

Now that I think about it, and from what I've read, for the first plant harvest I think I'll go with <1% amber. Basically, just milky trichomes. Serious cerebral high. Then at the ~70% amber coverage on the other one, a full body couchlock high. I've been reading, researching, and reading and researching some more over the past few months. Everything (so far) says that milky=cerebral, and amber=body. I really want to see the 2 types of euphoria at their maximum degree of separation. I've also read (and I don't know if it's true or not) that milky vs. amber has much more to do with cerebral vs. body high than sativa vs. indica does.

 

[CrazyChef]

On another note... Does maximum potency really equal better weed? I've always lived by the motto "quality over quantity". I can see how the cerebral vs. body high is a completely subjective matter, but if cerebral is the main goal, then maximum yield isn't the most important aspect because maximum yield equals longer grow time equals higher percentage of amber trichomes. Higher amounts of amber trichomes will obviously lead to a better yield (because of the longer grow time), but is that necessarily the desired end result? If a cerebral high is the desired end result, then maximum potency may not be the best option in this case.

 

[zeroday]

IMO, its completely subjective. I like the balance approach. I've smoke weed that made me so damn stoned that I wondered what purpose being that stoned could possibly serve, other that to be completely effed up, that tasted like shit and made me choke. I've had the opposite end of the stick: Weed that tasted and smelled like the heavens, but barely got me stoned.

I like a balance. I really enjoy pulling a bud from the jar and looking at it, then smelling it. Then I grind it, and smell it again to note the difference between the jar smell and the fresh grind smell. Then after getting it packed into a bowl, bong or bone, that first hit, letting it role over the tongue and sit for a few seconds before allowing it into the lungs. Then after a minute, feeling the effect of the chems inside the taste and smell. MMMMMMM! Balance of all of it.

In my opinion, potency is for the fiends. Don't get me wrong, some of my best friends are fiends. Its all good. I just like the balance of what this lovely thing we consume provides more than the extremes.
