what brings aromas out in plants ?

Sulfur

Sulfur

I'm thinking seaweed . apparently contains lots of sulphur, and i am going to try applying it all the way through the next grow

You mean terpenes, I assume. I'm wondering if that's good or bad. It'd be good if the plant is producing more than it can keep.

Terpenes are part of what are getting evaporated along with the other stuff that trichome evaporation takes with it.

Yes, keeping trichomes intact increases the entourage effect.

I would also venture to say that when you water and you smell in increase in aroma it's the plant pushing sheets of new trichome out now that it has a readily available reservoir of water to pull from. Trichomes don't just form on flower. They form all over the plant but are usually really tiny to the naked eye.

That's helpful. Thanks. The capitate stalked trichomes are the ones we can see. The bulbous head contains terpenes and cannabinoids. I imagine they're stored in something like a bladder because they're volatile and the plant needs to have a way to store them. This makes me wonder why heat would be a reason for the plant to release them. It seems likely it sends a message that conditions are right for fertilization. If that's true, it might be possible to condition a plant to produce more of these VOCs. -- just thinking aloud

From what I've been told, VOC percentage is really more genetic than anything else. Yes, grower skill can improve on it but for the most part it's all genetics.

Obviously, if I'm running lights on at 95° the percentage will be low but on a normal grow it doesn't really fluctuate that much. If you can max out the potential of the plant then you'll have a great entourage effect but superseding the genetics is pretty hard to do.

My last run I grew seven plants from seed all in the same 100 gallon pot, I had one plant that was initially my favorite; great dense bud structure and very pretty in veg. She turned out to have 0 recognizable aromas, almost smelled faintly like nuts. Weirdest flower I've ever smoked.

I hear ya. Most people want pretty purple flowers that glisten in the light from all the trichomes but I've smoked stuff that looked worse than mexican brick weed but knocked me on my ass.

Around here I grow the same strain every year; my personal medical strain.
Organic soil in large pots and I give them a lot of veg-time to grow before I flip.
These girls are notorious for being very mean. They spray oils in defense and that can irritate my eyes and lungs a tiny bit when I am mucking about in there. They have me trained to trespass lightly.
My point is they just don't like be tussled about with me moving them around. That is when they really put out the strong smell.
Other wise they seem to communicate that they want water with smell. Perhaps they communicate with each other too.
Co2 levels seem to effect the level of smell as well.

They get worse the more mature they get. Down right mean! Almost bitchy.
Only seeding them calms the scent down.

So I agree health is the thing and obviously the strain determines what they smell like. ---

Oh I just remembered a cool true story.

So like I grew and flowered in the tents two years back.
I went to harvest and I am sitting on the floor doing this in front of the furnace air intake. So like they really put out the smell when they are being murdered shall we say and that wafting strong scent was going into the furnace as it was running and unbeknownst to me it was being broadcast over the whole village!
So I hear a pounding on the door and a neighbor from two blocks away is trying to see if it's my house the smell is coming from. I happened to be the only neighbor not out sniffing the chill weed air.
Once I went outside it was like the whole village smelled like my weed! Mind you these are fresh cut not drying in an oven.
So word of warning A furnace can amplify and broadcast over several blocks and EVERYBODY will smell it. -- True Story.
Later the police commented to me ( it's a really small village) that they figured it was me because I was the only one not outside looking for the source of the smell.
Mind you Po Po knows all about my grow. They have been in here and I am licensed.

Honestly it smelled really good. All heated up and blown out the chimney vent.

Great story! How do you get a licence?

 

[Zzzax]

Great story! How do you get a license?

Medical Card: Pay the State + Pay a private corporation = license.

license meaning: a permit from an authority to own or use something, do a particular thing, or carry on a trade

Politically, my view is, any use is medicinal. Personally: I work with abstract mathematical constructs and (my medical strain) cannabis helps me function that way.
I'm writing a paper concerning the Collatz Conjecture.
I just wanted to say that Cannabis can be extremely beneficial.

Sulfur

That's a myth spread by fake weed experts out of California.

Cysteine contains a hydrogen sulfide group, that's the only S contributing to Cannabis aroma. Pot growers don't believe in aminos though, so..

Cannabis aroma comes from terpenes. Terpene production is mostly genetically determined.

That's a myth spread by GW/Jazz Pharmaceuticals out of the UK.

Cannabis aroma comes from amino/carboxylic acid pathways, not terpene synthesis.

I have noticed that rubbing the stem produces a smell but the higher i go up the plant the less it is ?

Your plant is eating itself for nutrients. Many nutrients are attached to proteins in the plant. Usually potassium and zinc. Even "immobile", you'll see brown leaves and chlorosis down low from the oxidized proteins. The plant destroys itself to extract the mineral.

Guano has killed more quality than anything over the past 50 years. White tips, deformities, reduced leaflet count, ugly dull weird colored plants, light dimming, hollow stems, terpene sprays, this shit wasn't normal 20 years ago like your peers tell you it was. Excess P will load your buds goopy with gross black resin that never develops into cannabinoids or good flavors. You can't get high off the shit.

Proteins are where many Cannabis aromas come from. Proteins are made from nitrogen. Potassium is the "quality" molecule essential for acid metabolism. Who told you to boost phosphorus? These grow forums have been chasing quality for decades, and all they've done is lower everyone's standards. Most growers don't need carbon filters anymore thanks to the internet. And Sour Diesel isn't sour or loud anymore.. Lol. Some say there's a conspiracy against weed quality.. personally, all the info is bad no matter what theory you believe.

Everyone is under feeding, and being told they overfeed, and when they investigate raising nutes, they always raise P too high, and S too high, and Mn too high. And everyone still uses calcium nitrate instead of organic calnit, so they have a huge energy drain.

Same pattern since the 1970s. It's why the plants got so small and had to be harvested in 10 weeks. No one fed the big plants enough. Indica is the result of shitty grow info from the era of Green Merchant and Jorge Cervantes. (Hence the shitty undeveloped weed you saw in old Hightimes, grown by all the scene's legends, who pushed indica just because they couldn't finish a sativa.)


People think they are picky about weed strains ever since legalization. Young pot growers made up this bullshit about "dialing in the environment" to sound like they knew what the fuck they were talking about, while completely ignoring the only thing that matters; Nutrition. Imagine believing temperature is more important than diet..

I would also venture to say that when you water and you smell in increase in aroma it's the plant pushing sheets of new trichome

Have you grown water only? Once the soil runs out of energy the smell depletes. Organic nutrients are attached to energy resources such as fatty acids, carboxylic acids, and aminos acids that are essential in Cannabis aroma pathways.

Hey Cheers.. I'll Compost to that! Any hints?

what does a study about yeast have to do with plants? you could have shared something about dogs?
yes if the temperature is under 14C no matter what you put in the nutrition she is out you can call again later.
yes i grow in water and the shit stinks outside the house on the street.
and guess what she eats grams of sulphor daily

 

[Zzzax]

Sounds like it might compost.

I use a product called MagPro from Dynagrow that contains sulfur. I use MagPro mid to late flower, and immediately after applying (1-2 days) my plants start to stink strongly. I thought it was my imagination, but after 5 grows, I've noticed this every time. Its not subtle either, it goes from mild to high odor in days...

I'm thinking its the boost in sulfur?

 

[RegularRebel]

I am trying to work out what it is that makes a plant produce strong smells . I have a 2 auto plants just 4-5 weeks away from harvest , they are bulking up, they are sticky , ive been feeding plagron A+B for coco , silica, and a bit of guano top dressing.....but there is zero smell . I did read once that it is sulphur which affects smell and the only other thing i can attribute it to is stronger lights ? or perhaps heat . i have noticed that rubbing the stem produces a smell but the higher i go up the plant the less it is ?

Crushing them and chopping them up releases a lot of aromas. I do that with stems and leaves for aromatherapy.
