breeding for terpenes

I agree with that about the % & composition of the terpenes but the nose will tell the aroma & the effect on the limbic system, which an analytical test will not do.

Keep on growing :)

I am not so sure what the nose can tell, on ID'ing the 130+ terpenes. But I do agree that I can often pick out a best plant from seeds of one variety, just from smells, assuming that they are similar in yields, flower to leaf ratio, and other important factors.
And once you understand what each terpene or combination of terpenes contributes then analytical results will allow predictions without smelling or smoking, it is not so far away.
Breeding terpenes is certainly possible.

I use Iron Labs too and I think I might know you in person too. Nice thread too btw.

I figure terpenes are more a response mechanism. So if you change variables you should be able to change terpene response. for example environment or nutrient changes taht help shift terpenes. I was told to play with sulfur levels to get better expression and i have noticed playing with temps etc changes things.

I ask for OG's I get OG's. Sweet :thank you:

My lab got a gas mass spec machine they are establishing "baselines" with still. They don't offer tests on it yet. They will run our samples to get results, but they don't offer the service to us yet. That being said, I may try canalytics next, I heard they offer it.

Instead of getting everything tested I think i'm going to organoleptic test everything and then try the ones that score best on the mass spec. If I learned anything from testing its that my 5 senses can test pretty well also.

So Sam are we already breeding for terpenes just by breeding for desirable traits? Or are they autonomous of other traits. Can you stabilize terpene production as you can stabilize other desirable traits?

I don't know if its multiple terpines that make up the smell I like or just 1. I know I can smell similar smells in different strains. I find a similar smell in the Indiana Bubble gum, the Death Star, Sour diesel, and now my chem 3 (which is Chemd x Sour Larry OG x Alien technology) I know it's similar in all of them and it's what I like.

Hopefully I will have the answers soon and I will put them here

OK now this sounds plausable...

So maybe a plant has a set of Terpenes it can "possibly" produce and the better it is grown or the more "happy" the plant is, more of the terpine profile is exhibited. So I wonder if you grow something poorly will the terp never be produced or its just so little its negligible. Conversely, can you dose it with sulfur or something else to produce a terp it would not have otherwise.

I know stuff smells different when different people grow it but is that from actually having different smells or just from having different concentrations of the same smells?

Thanks for the input everybody

What up SwissCheese?! :tiphat:

What up!! A good source of sulfur is molasses and/or epsom salts. As far as terpenes go I've read pieces by tga talking about breeding for terpenes either here or riu. I have some genes to work with too maybe we can pull off an epic collaboration.
 
ok day 65 now. heres the chem 1 the biggest yeilder. it was taken down after the dark cycle after the pics were taken

ok Chem 3 Here (the keeper). #2 got chopped at day 59 totally ready. This one takes the longest. could go 70 if you want but totally done at 63-65

That one looks like a big yielder and has a really nice structure. What smell is she putting off this run?

it has my favorite smell ever. I'm not sure what is but I'll find out; hence the thread. I think its Larry og with a chem undertone. Its very flowery perfumey without the lemon with a fuelishness. A Way better smell than the alien dawg which always looks the best imo

I have a feeling the whole stoned/high thing is merely about afghanicas having more terpenes, and possibly a different more sedating set of them.

How much $$$$ do you have to pay to test the cannabinoids? I'm working on two separate cbd lines, other from "indica" and other from "sativa" genetics, hopefully I'll be able to paint a picture on how the terpenoids affect the buzz.

great read. i am just an advanced pollen chucker not really a breeder. bump to keep up. whats the average price for testing your herb ?b i think i want in on that. and what abut that genetic /dna whatever testing . heard they can record the genes so it can be traced eventually with enough samples.heard pigs are doing it. hmmmmmm
 
it costs 300 for a 10 pack of tests. And you have to be a member (100 to join w/ 3 free tests) I'm not sure if you could just do one test as a walk in wanting to test one sample...

I have paid as much as 75 for a test and they said that was half price. That was also when there was little to no competition

Thanks for the props supermanlives. I'm not sure about mapping the dna, I know my lab doesn't do that. I will look into it though... They say they have to work for a long time after hours establishing baselines and seperating the spikes in the results for the new mass spec machine.

They couldn't tell me exactly when i'd be able to pay for a test including terpenoid analysis but just that it would be extra. They couldn't tell me how much extra either...

Ok it's on then as you know I'm a major flavor aficionado and I'll post up a smoke report for you. Anything that resembles og or chem I like but you already know that. What males are you going to work with or thinking about using?

I don't get how you can breed for terpene's if you do not even test for them like you do the Cannabinoids. Good luck....
Imagine breeding for THC or another of the Cannabinoids, and not testing the Cannabinoid content.
Do you want to increase a single terpene or all of them? Set a goal. And then do it.
It is not so hard, if you have analytical backup.
-SamS

What do you mean you dont get it? Maybe the test lab he uses doesnt test for terps but thats not the case with all. The z-nose is fully capable of testing cannabinoids and terps and gives you a genetic footprint. The local company who owns 1 takes it to third coast compassion in ypsi twice a month.

So many things effect what a plant produces. Pest and pathogen attacks aswell as training/bondage, environment etc all effect your profiles.

Even with all of this technology, multiple tests need to be done and an average taken. Each bud from every location on a plant will test different, 1 bud is in no way indicitive of the whole bag.

Until an entity that is the last word in callibration arises, who the fuck knows what youre getting.

How accurate are these tests? If you were to test half of a bud one day and test the second half the following day under a different name, would the results be identical? You would think they would have to be within 5 percent of each other or closer, or I would conclude the testing facility is bunk.
