subscribed......very nice stuff.
Gypsy you are taking over the site with awesome information......keep it up!
Great info. Makes a lot more sense than buying a microscope to tell if your plant is ready to harvest.
If you want a soaring 'cerebral' high: Get yourself a tropical sativa that contains a high level of THC-V and grow it until it is ripe.
If you want the narcotic couchlock stone, grow a rugged indica until its ripe.
Notice a pattern of growing it until its ripe? Its a really good rule to live by.
just for clarification, THC-A is simply the un-activated form of THC. it is what is on the bud before it is burned. it isn't a predecessor . . .
other than that, good stuff. I don't agree with the use of cannabinoid terms to determine high. I think you should stick with the sativa/indica extremes. pretty much the easiest way to define types of weed. THC-V is primarily found in indica varieties, so I don't think it's going to give you that 'souring cereberal high', I think it's more likely to give you a body high.
so just stick to indica/sativa and it should prevent lots of confusion.
Tetrahydrocannabivarin
Main article: Tetrahydrocannabivarin
Tetrahydrocannabivarin (THCV) is prevalent in certain South African and Southeast Asian strains of Cannabis. It is an antagonist of THC at CB1 receptors and attenuates the psychoactive effects of THC
I think we have some confusion here. I don't want to split hairs , because I don't have any formal chemistry training, however its my understanding that a predecessor is just that, THC-A will become THC with certain conditions (usually heat and time) either way, it could be I just misused to term, if so, I apologise.
As for THC-V, I was a little taken aback when I read your take on the subject, as it contradicts what I've always assumed to be the truth. I 'm assuming you are a student of wikipedia (no offence intended, I'll be the first to admit that wikipedia is one of my sources.) I'm also assuming that it is this article (http://en.wikipedia.org/wiki/Tetrahydrocannabivarin) that you used as reference. It really is looking much the same as when i last read it only with just about every reference to subspecies sativa having been changed to indica. I don't really get it, as this is always the information I've been taking as gospel.
Now correct me if i'm wrong, but in my experiences, southeast asia and south africa are both famous for their exotic sativa strains.(thai and durban poison come to mind). As a matter of fact, I've never heard of any Indicas being natural to that part of the world, generally they are more associated with cooler mountainous areas of pakistan, siberia and the like.
I'm going to have to do some homework on this one, I really hate to share information that isn't true, and you have me now doubting myself.
I'm pretty sure the point that Zeus was making, from my
point of view, was that you need not over complicate the
issue of harvest time with unnecessary science; When the
plant itself if completely capable of expressing it's deficiency,
if any, and when it's ready for harvest.
See the whole plant... not the chemistry.
Especially with amateur grows that have no real controls
that are congruent with any actual study.
Just sayin'.
EDIT: To the dude with the 10 week SD... give it 2 more weeks.
