Jack Harer (Sensi Seeds) - Genetics Cleared up?

I got two seeds of Jack. One was a male and the other, well the other was female and they were all living in a single ...Wait where was I?

Ok So I started these two indoors with some other strains. I moved them out doors and the wind snapped my jacks right in half. I decided to stop focusing on the jacks and set them aside. They were stunted in growth and had a hard time growing. I took the male and pollinated the female and made seed.

I smoked the end result of the stunted, seeded female. It was sativa dominant and lemon tasting.

My questions: *Will my offspring have the same 4 phenos that the original Jack had? Can I still get the indica pheno even tho my male and female jack was very sativa looking?

*Can i get 2 unwanted phenos from jack harer sensi(male/female) and cross them for desirable phenos in thier young?

*Since i have the first male pollen, how will this help me in backcrossing(inbreeding)? What will back crossing this strain achieve?

*I heard you cant take two low potent plants and make a potent one? How is this true if phenos arnt expressed until later gens?

*I keep hearing about a greasy pheno from jack harer(Sensi). I want this pheno as i just grew some pineapple express and out of 4 only one was greasy(not sticky if lightly touched). So can i still get this greasy pheno from jack H if my intial female wasnt greasy?

Ok Last one: I grew some rocklock by DNA and it smelled like Mountain Dew Baja Blast from taco bell. When I cut it down the smell changed to "New unrolled carpet". Is this a certain terpene? I also had one that smelled of old womens perfume(Horrible but potent), Sage or chicken spices. Some strange flavors that grow.

hope im in the right place in new here.

Oh yea also, I hear jack is easy to grow yet from what i see its small lengthy branches dont hold up to small wind? Also its picky on soil PH, temp...Everything i guess. Its one picky plant in my op.

Any comments? Thanks in advance

You will be missing a lot of genes only crossing two plants. Some phenotypes will no longer be available to you. Nature of the beast.

Backcrossing will lock down some traits. Maybe desirable, maybe not. And maybe not many.

Sativa dominant hybrids tend to be pickier and sometimes as picky as a real sativa. Being a real poly there will be a lot of variation there. Some plants will be a lot more desirable than others. You really can't do good selection from 2 seeds in this type of line. You might get lucky and find the best example (easy to grow, potent, yielding etc) but that's not likely.

Cannabis is capable of producing a diverse array of terpenes.

Isn't Jack Herrer at this point an IBL, or pretty close? If you pollinated the lone female with the lone male, you are narrowing the selective pool and will get lesser genome expressions.

I don't know I'm high and making pancakes

How will i be missing genes if the source(Sensi seeds) did all the breeding? It Shouldnt matter if i plant one or 1000 they will still be within a pheno range(taste,high, ect) because mom and dad are the same right?

I get you grow 1000 and select the best...But am i wrong to say that it has good genes in all 1000 because the mom and dad were top notch? This is just an example BTW. Or can a good mom and dad produce some bad seed?

I crossed My rocklock(Smells like new carpet) with the male jack harer and the resulting seed took on the indica leaves. Hopefully by having such a unique smell and taste i can get a better understanding of mixing strains ect.

*When you buy a pack from a breeder do the seeds come from the same plant(brother/sister)? or can u get seeds from different plants? Im not sure how standardized the biz is?

Well for for one thing, remember not every plant has all the same copies of its parent plant. It only has half, from each parent.

Now the genome expressions are dependent on what's recessive, dominate and dependent on alleles.

Now in a 1:1 cross, you are only including two parents for the beans you make. The more females and males the more genetic diversity is possible, for good or bad.

Im kinda confused because i grew some OG 13 that was fem. The resulting plants were all genetically the same(look,smell,high).

But when i did the same with pineapple express i got different variations. Some were sweet, some stinky, some potent, but for the most part the smell was the same.

Even the Leaf pattern had slightly changed in one plant.

So why the variation with the pineapple express and not the OG?

Could Soil conditions, light, nutes, temp be affecting the pineapple or are they genetically different from one another? I wish i knew if the seeds in a pack came from the same plant.

Well its been a while since I've been on a genetics course, I've got a couple ideas. I'm not certain by any measure, just trying to explain/help.

Feminized beans can be done in a couple different ways. One could self (create male flowers on a female plant, resulting in female pollen) a plant or its clone, and essentially duplicate (but not exactly as genes do express differently when crossed even with itself, genetic recombination) it's genetic code for its offspring. Or a second way for feminized beans can be taking a normal female plant, and selfing (creating male flowers like the other example) a different female plant creating an F1.

Now perhaps both are just S1. If the OG13 was more uniform, it could simply have less genetic variation. If the pineapple express showed different genotypes, it could simply mean it had more genetic expressions and was less uniformed in its genetics.

Just remembered the OG was cloned from a mother plant. So the clones didn't have variation but the fem pineapple seeds did. Makes sense. I didnt know fem seeds have slight genetic differences.

Sannie is the only guy who has stabilized JH AFAIK. It wasn't a worked line when released. Maybe Sensi has done some work stabilizing but I doubt it.

Feminized seeds can be dramatically different genetic expressions.

Sig worthy

Sensi Seeds Jack Herrer is NOT! I repeat! NOT the real thing anymore, not like back in the 90s. I had a friend that had a phenotype that smelled and tasted like peaches. I miss knowing seeds would give you some unreal shit but its not like that anymore really i find...

Youve just won a KLITE award. I attribute those to people who say epic things. Congrats.

Thats interesting because i have read people raving on sensi's Jack Harer. My cut smelled of lemon and lavender. Look at this from 2008? https://www.rollitup.org/t/sensi-seeds-jack-herer.117328/

i agree, sensi had a good reputation for good seeds back in the 90's. i bought feminized super skunk recently and was very disapointed. the plants looked nothing like the plant in the big book of buds, small calx's few hairs, and smelled of freshly cut grass, i threw it away,, no skunk smell and very low producer,,but nobody wouldve wanted it anyways.. those seeds were kind of expensive and out of 5 feminized seeds not 1 was anything near what sensi says it should have looked or smelled like..i will never buy sensi seeds again..however i still have a pack of feminized shiva skunk and skunk #1 by sensi but havnt planted them yet,, maybe there is hope for sensi if 1 of those seeds produce a good plant...nirvana seeds are cheaper and in my expieriences ive had better plants that were more uniform and close to what they said they should be at less than half the price of sensi seeds...what happend to that seed co?? in the 90's they sold seeds at a more reasonable price and the seeds were more like what they described the plants to look and smell like!!!! SENSI SEEDS SUCK

I Got them as replacements for out of stock stuff...They are not fem and was said to be some fine smoke with a 20% THC level. Im not saying they are worth the money but why are people commenting who never grown it? Anyone here with experience on sensi jack harer specifically from a 2013 stock.

klite not to dispute what your saying, but isn`t that what made jack famous. its a 3 way cross that has a deep genetic pool. mainly it has the 4 main phenos but then you have those others that come thru randomly. i may have misunderstood your point.

What you say is soooo true. When im really looking for a male il spend almost 1 year growing as many of the males i have offsprings as i can to see which male passes which traits at what incidence onto the prole. I cant work with many plants at a time and have to keep them tiny, but for traits like taste, smell and potency its ok.
Heres some pollen leftover oif a chemdog d male i think was the best out of 7.

Yes what you say is correct, however sensi seeds has let their genetic stock go to crap and the seeds youre getting nowadays will not have the same phenotypes. A mate grew jhack herrer earliuer this year, brand new seeds straight from sensis shop in holland. out of 50, 12 didnt germ i think he ended up with 15 or 16 females and the line just all had this spicy hazey undertone one or another slightly more accentuated phenos but nothing clear NOR spectacular. Dont get me wrong he found one that was potential keeper, though nothing spectacular like back in the day.

man ur killing me.....i got a pack to run this year, i`m hoping for that fruity taste with a hazy undertone i got before. its all good as long as i can find one good one.

The best Jack I've had is very peppery. It can be quite amazing. Sannies I believe is more lemony with the peppery undertones with reported frankincense phenotypes to be found as well.

I think I'd go with Sannies version.. just popped a fem bean in fact the other day. But I'm sure there's probably good plants to find in the Sensi version too. But everything I've read indicates they lost the parents at some point.

I think im going to pack up my rollitup bags and try another site.
