THC vs CBD
We have all seen the question "when do I harvest?" and the usual answer is when the hair is turning red. Here is a question for some of the veteran growers below...
THC (Tetrahydrocannabinol) gets a user high, a larger THC content will produce a stronger high. Without THC you don't get high.
CBD (Cannabidiol) increases some of the effects of THC and decreases other effects of THC. High levels of THC and low levels of CBD contribute to a strong, clear headed, more energetic high.
Cannabis that has a high level of both THC and CBD will produce a strong head-stone that feels almost dreamlike. Cannabis that has low levels of THC and high levels of CBD produces more of a buzz or stoned feeling. The mind feels dull and the body feels tired.
When the plants are actively flowering, the resins contain a higher proportion of THC than during the vegetative stage. During the later stages, when flower production has slowed, THC is degrading to other related chemicals such as CBD. It is thought that THC is mainly responsible for the "high" and CBD for the more physical, "stony" sensations such as lethargy. If you want a clear high then harvest when approximately 35% of the pistils (little white hairs) have turned red or brown. If, on the other hand, you prefer the heavier hit you get from something like pakki-black resin then wait until 65% of the pistils have changed color.
QUESTION: Seeing as how Sativa is a more of a mental high and Indica is more of a physical high, would it make sense to harvest Sativa early and Indica later for optimal results?
BTW, here is what else you can find in your favorive herb...
CBN (Cannabinol) is produced as THC ages and breaks down, this process is known as oxidization. High levels of CBN tend to make the user feel messed up rather than high.
CBN levels can be kept to a minimum by storing cannabis products in a dark, cool, airtight environment.
THCV (Tetrahydrocannabivarin) is found primarily in strains of African and Asian cannabis. THCV increases the speed and intensity of THC effects, but also causes the high to end sooner. Weed that smells strong (prior to smoking) might indicate a high level of THCV.
CBC (Cannabichromene) is probably not psychoactive in pure form but is thought to interact with THC to enhance the high.
CBL (Cannabicyclol) is a degradative product like CBN. Light converts CBC to CBL.

hells yea. go research trich colors. the chronological order of trichome color and effect is 1. Translucent - Non-psychoactive, 2. Cloudy - Cerebral/Hallucinogenic 3. Amber - Body/Couch-Lock, 4. Dark Red/Brown - Degrading THC.
However, you can always get real creative and (for example) harvest an Indica while its trichomes are cloudy. In my experience, this creates a creeper-high but I don't have much to back that.

there is no reason to pull a sativa early, they typically take an additional 2-3 weeks longer than a good short indica. plus many sativas will continue to produce additional buds late in the flowering period. the sativa plants give you more of a soaring high even if you pull them very late.
personally i dont pull any plants early, i like all of the strains i mess with to fully mature.
I don't know about the plant producing any THC during Veg.

it's CBN CBD-->THC-->CBN
THC is degrading to other related chemicals such as CBD.
Like mrCRC420 said. I allways go off the color of the trichomes, since thats where CBD is being cyclized to THC
harvest when approximately 35% of the pistils (little white hairs) have turned red or brown
Research UVB light and THC production if you want to increase THC potency, by increasing trichome growth.
I have read that Ed Rosenthal recently has claimed that terpenes, the stuff responsible for the smell and taste, may also play a role in the quality and type of high.
Sweet post man! This cleared a lot up or me, but I think I would add a comment to harvesting early on sativas... Most of the popular quality sativa strains that are on the market, like greenhouse's super silver haze, fully mature with low CBD ratings to begin with so you might just lose out on Terpens, like mindphuk said.
I personally have harvested clones from the same mother at different times and felt like I just lost out on taste by harvesting early, but gained a more productive high because I wasn't lethargic (LOL great word btw!).
"Gangsta Rap Made Me Do It."
also the main idea behind it is they just outright take longer to mature (sativa) ultimately we are waiting for the trichomes to reeach a certain point as they will show us the aroundabout effect of the plant.
now i have time to answer i think ill put my takeon the sitcho and see if it helps, and also the latter is possible by harvesting an indica with clear or milky trichomes will give you less couchlock effect and the more amber ones will give you a more sedated stoned effect no matter what the strain. the main differance is size and amount of time the plants take to mature though indicas will alwaysgive you a more stioned effect and sativa a energetic so to speak it all levels out in the end. the trichomes colours help us modify the stoned/high of a plant a little.... im a couchlock fan so i like my medicine well done lol. \
also the numbers i go for if using hair colour is 80% after this the degration becomes more noticable. i hVE lao found some plants that were best when they were overripe. watching a blank tv kinda shit lol. umm but yeah the when the trichomes areshowing about 35% amber to 60/70% i find is goodf. the fact that they are turning amber isnt shwing degrading yet thingk of it as reaching peak thc production the idea is to harvesst at peak production and before it starts to degrade if that makes sense
anyhoo dilly dally shilly shally.. im smashed and yeah i think i dribbled some shit there
umm i eas wondering if yur going to update the cannabinoid types profile things as theres more than what youve listed i think i thought this thread ws going to go a different way to this lmfao.
still theres some good info to be had for some people.
