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.

Nothing of what I say is factual, nor do I.. do.. fuc, im so fucking baked right now....

yeah
nice post

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

Like mrCRC420 said. I allways go off the color of the trichomes, since thats where CBD is being cyclized to THC

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.
