Funny you mention cherry cola, had a buddy run the PNP x i made indoors and described it as a grape soda candy. Got another buddy that ran the Trop Cherry dom x and waiting to hear back from him.
PNPK
I ran one outdoor during winter, ugly little plant that tasted like crayons. Kinda cool/crazy looking back at it.
None at all
Great photos! Cherry cola is a appealing terp profile for sure. If you find yourself at the dispensary check out Blems Boasy. It’s some kind of cherry kush cross that has this really nice cherry citrus soda flavor with an og backend.
My friend is running the TCxPnp keeper x (Hawaiian Sativa x Sour Diesel bx2) he said the terps are currently indescribable, so curious how it ends up.
“The cannabinoid content profile analysis revealed that all grafting treatments raised the THC level in FSE’s inflorescences by 8–12 % in comparison to the non-grafted control, and the THC rootstock led to the highest THC level.”
Imo, grafting technique might just allow the plant to reach closer to its genetics potential. Therefore improvement in terps and even thc content seems only logical.
Btw, I have TK clone in flower grafted on Trop Cherry x Pnp rootstock and where the plant previously struggled with water intake (vs other plants) she now drinks as fast as others.
Way cool, thanks for sharing. Personally I used a hearty gushmints clone as a rootstock and a lanky og as the Scion. My thoughts were that it would have stronger branching and require less support. In the end though the plant performed almost identically to the ungrafted ones and took an extra couple of weeks to heal. Seems useful for keeping multiple varieties on the same rootstock as a mother but I didn’t get the improvements found in the paper.
I’d be curious to see how a photoperiod rootstock handles an auto flower Scion.
Have you noticed an improved growth rate on slow growing varieties and does the bud structure stay the same , plant structure affected ? any effects on the terp profiles ? Been thinking about all of this for a while and did not realize people had been making advancements in this area with cannabis.
There is a amazing tasting variety of tomato that has very slow growth and poor yields that is available grafted onto a rootstock that makes it grow fast and yield better then any average tomato plant , those plants sell for 5x the average price and sell out before planting season even starts.
Right at the start of week 3 and i just picked about a dozen pollen sacs off my notso x triangle. Notso x chem and 5150 x chem91 are still good, along with all the other plants.
Probably going to keep her unless she goes full herm because im excited about the cross. I have clones i might run next to see if its just an issue going from seed.
update from around day 45 flower. I suspect the herms might have been caused by heavy feeding. She is definitely more sensitive to nutrients than any of my other plants. Recently ended up burning her with organic nutes so i figured id update. (neptunes harvest flower emulsion is what pushed her over the edge and burned her)
Yeah, its great to experiment with the technique but it has its limits. The lankiness, terpene profile, hormones… its given by the genetics of the scion, as well as the autoflower / semi-autoflower tendencies - which I have tested and it proves the autoflower trait remains if grafted on photoperiod root stock.
Think of it more as a tool to help the plant to reach its potential.
I did notice improvement in growth rate with Zkittlez clone scion for example, however the terp profile, lankiness and overall terrible growth pattern of Zkittlez didnt change. It just grew faster. Terpene profile is the same but intensity might be affected depending on the rootstock match. I believe bud structure might be affected with grafting to certain extend as well, as it is affected by environment, nutrition regime and other factors.
Bubba S1 from CSi, this is the strongest Bubba I have found yet, reeks of acrid skunk & pine, quite pungent smell compared to the others as well and keeps in jar for a long time. Excellent smoke.
This is really exciting! Keep up the great work. In a big fan of grafted trees but in skeptical of the value for short term crops. My experience with tomatoes tells me that you CAN get better yields or growing potential but that’s almost entirely negated by the extra labor involved in grafting and the time to recovery. At one point I even had a grafting gun and was grafting like 100+ tomato cuts a day. It absolutely does result in more plentiful and healthy plants but hot damn if it’s not a ton of work.
310 unopened, Full CSI Humboldt packs for sale. Going through tough times. DM me your cash offers on the whole lot
Damn I really hope to find something good like that in my last 5 S1’s… did you have any trouble getting beans to pop and sprout at all?
USA? Canadia?
Got an easily copy/pastable list? Maybe for the seed trading thread or make a thread in the trading post 
If you haven’t already…
There are a couple studies where, yield was increased with, no changes in terp profiles transferring from the rootstock… check the links in this one:
I read that already actually 
I can see the potential in grafting strains with poor root systems onto healthy root stock how ever I’m curious about a slow growing plant that has a great root system but grows slow like bubba kush being sped up in growth threw grafting onto a fast growing variety.
I’ve also found with time plants that grow poor root systems generally want a different medium, nutrient, or micro environment and once that is dialed in they do just fine. I think some root systems grow for very specific environments and our modern mediums may not always be the best environment for their development. I acknowledge that there are plants that genetically just have a poor rootstock but I think they’re less common then are issues with the growing environment.
well, now you’ve tickled my brain. so, if im attempting to backcross, that would probably require me to grow the seeds out and after that dig through to find which pheno best resembles the parent. so would grafting back to the old parent THEN making an s1 from the scion be similar to a bx2? or would those s1’s be like a bx1
Understood, I was considering testing bubba on a strong rootstock like blue dream, whose roots are freakinh monsterous. She does grow fairly quickly once dialed in though, but never quick enough
Thank you! Will look into these for myself. Pretty bad at watering since I’m always preoccupied with something else
Another benefit of SIPS for sure, just fill the tube and with the air gap, keeps the plants super hydrated, and oxygen is no issues. The Air Gap IS the key no doubt… always make sure to put in perlite or rice hulls for aeration(there is a little cactus blend in the recycled soil, which has pumice, but it isn’t much). Dirt Maker for life… it only gets better. Keep them thumbs green folks.
