Havin an early morning look at Ruderalis Indica, looked at the price and thought MG, so cheap so thiunk Im gonna get me a pack, I just NEED to be sure of this: 100%autoflower?Pretty much a neccesity As the space will afterwards be used for the regular plants (hopefully Jamaican pearl and mybe mexican sativa) so I just need something that wont be there in a few months. It said on the overgrow strainguide that it cud reach 150-200cm! thats pretty big and yield was fairly high aswell, not too fussed just wanna try it. Anybody had luck?

never grew it myself but im sure you can find a few auto flower phenos in there good luck

Hey

Whats the THC CBD etc on them badboys? And do you know anything about the genetics of the strain?

not sure if it is 100% auto, but even so different ruderalis take different amounts of time to finish, lowryder is probably the quickest, this one may take a fair bit longer, i think CF grew it once

Hey I do know about ruderalis strains. But because im lasy heres a few passages from another website.

What is Ruderalis?

Cannabis Ruderalis is a subspecies of Cannabis Sativa. The term was originally used in the former Soviet Union to describe the varieties of hemp that had escaped cultivation and adapted to the surrounding region.

Similar Ruderalis populations can be found in most of the areas where hemp cultivation was once prevalent. The most notable region in North America is the midwest, though populations occur sporadically throughout the United States and Canada. Without the human hand aiding in selection, these plants have lost many of the traits they were originally selected for, and have acclimatized to their locale.

Though they contain little THC, these plants hold large potential for use in breeding, both in hemp and marijuana applications. Early flowering and resistance to locally significant insect and disease pressures are but a few of the important traits present in these feral populations.

Thankfully, despite years of US government sponsored eradication programs, these wild plants still remain in bountiful abundance.

Early flowering explored

The marijuana strains most of us have been familiar with begin flowering once the night period reaches the individual plant's critical night length. This critical length varies depending on where the strain originated. Generally, there is a critical period of darkness required to begin flowering, and a second slightly longer critical dark requirement for it to ripen completely.

Many Indica varieties begin to flower when the day length drops to about 13 1/2-14 hours, while Sativas will often not begin to flower until less than a 12 hour day length is achieved.

In comparison, many of today's Ruderalis/drug strain hybrids flower automatically when they reach a given maturity, regardless of photoperiod. Even under lights on 18 hours a day, they completely mature from seed to bud in less than 90 days.

I've seen test plants from Mighty Mite hybrid lines that were started outdoors in early March, and had completely finished by late July. This could indicate that crossing auto-flowering plants to those that are photoperiod determinant lengthens a genetically predetermined period required before non-photoperiod dependent floral onset.

A second scenario is that within the ruderal strains that have been introduced to the drug gene pool there also exists genetic information of photoperiod adaptation to north latitudes.

Many of these Ruderalis/drug hybrids are also known for being very sensitive to other environmental factors. Things such as cloning, letting plants go too dry or getting pot bound can easily send them into heavy flowering.

The big unknown that still remains in these new lines of marijuana is what is actually causing the flowering on a biological level? Is there an internal clock, a genetically predetermined number of cell divisions that must take place before the plant begins to put up buds?

Another possibility is that once night-induced flowering hormone levels accumulate to certain levels within the plant it will begin to flower.

If the flowering is not dependent on having a dark period, these new cultivars could prove useful in backyard city growing situations, where streetlights and other forms of light pollution often prevent proper maturation of photoperiod dependent strains.


Problems and pitfalls

As these genetics further penetrate the drug cannabis gene pool they have potential to cause both harm and good.

Imagine getting mothers up and going for your next big crop and finding that at 60 days they all begin to go into full flower. A costly inconvenience at the least!

However, the potential for great advances is also there for the taking. How about auto-flowering Haze strains that ripen in the middle of summer, in areas where previously even the earliest Indicas would not ripen in time? Commercial growers could pull two crops per summer without ever having to worry about shading!

Breeding climate

One of the largest problems associated with breeding outdoor varieties for northern latitude areas like Canada or Holland is that the climate puts no pressure on plants to produce high psychoactivity. In fact it selects for the opposite.

So long as the breeder is selecting for high potency on a multi-parent level, potency can be upheld. However, if this same breeding program were undertaken in an environment that naturally selects for high THC plants (like highland Colombia or Thailand) the resulting average desirable cannabinoid levels would be much higher.

There is likely a threshold effect on the potential of any given strain as related to the environment it is being selected in. By incorporating auto-flower genes into the north latitude outdoor marijuana gene pool, plants would be finishing under more direct sunlight and warmer weather. This environment is much more conducive to high THC levels, thereby raising the threshold level for the particular strain.

Ruderalis and hemp

It is very likely that Ruderalis varieties have already made for an important advance in hemp cultivars. The variety FIN314 was developed from genetic material originating in Russia and seems to have the same auto-flowering trait noted in Mighty Mite and other hybrids.

FIN314 seeds that accidentally germinated in a Quebec farmer's field in early April were found in full flower by early June.3 Along with adding the possibility of twin crops in a season, this allows the oilseed variety to finish short enough to be easily harvested by current machinery, which clogs when fed the standard taller hemp varieties.

The genetic history of the parents of FIN 314 is unknown, other than that they were acquired from a germplasm collection from Russia. However, it is believed that at least one of the parents was a Ruderalis accession.4 If the widespread adoption of FIN314 by hemp farmers is any indication of the future of Ruderalis/drug hybrids with pot growers, there will be a mass dispersal in the coming years.

Buyer beware

There are still many commercially offered Ruderalis hybrid strains that are very low quality and should barely be classed as drug varieties. At the same time, the finest Canadian outdoor pot to have crossed my path so far was from Mighty Mite derived lines that were harvested in July and August.

The future seems clear for Ruderalis/marijuana hybrids. As many governments ease up on antiquated cannabis laws, more and more people will take up growing. A couple of auto-flowers on the back deck will likely fit the lifestyle of many more folks than would an indoor grow room.

Demand for stabilized, auto-flowering hybrids of high drug value, in combination with saner drug laws, will pressure marijuana breeders to move forward on bringing these to fruition.

Until then, the ability to have marijuana crops maturing at any time of the growing season should wreak havoc on CAMP style police tactics that have been accustomed to only searching for plants one or two months of the year. This, if for no other reason, seems ample enough to plant some auto-flowerers today!

Hope this has helped

Very Informative Mate .

hi N30SS,
just been looking at the sensi seeds catalogue.The Indica Ruderalis has a Sept. finish.It's not a 70 day seed to weed deal like Lowryder,even though they state that it's time, rather than photoperiod dependent.

Rockster

We grew Ruderalis in Sweden a couple of summers ago. We vegged it at home and put them out together with Early Pearl and Early Skunk. Only the Ruderalis finnished in the end of september or beginning of october. Only two out of ten finnished, the rest got eaten we guess. It got 60 cm high and pretty fat. We were lucky to harvest the weekend we did, mould almost got a hold of the plant. We could easily take the bad parts away. The high was not bad at all but not so very nice taste thou.

About the autoflowering I read that not every plant will auto bloom. I don´t remeber if it got to be around 50-50 auto blooming or not.

If you have bought some ruderalis that havent autoflower, the genetics of the plant are unstable. Lowrider will always autoflower ;0. Il try to explain how ruderalis flowers.

Most types of Cannabis Sativa use photoperiodism to tell when its time to produce flowers. To understand more il try to sum up how they do this. Plants can sense the lenth of light they recive and of what spectrum and even at ehat ammount. It is not yet fully understood the full workings of a flowering plant, but amonst other things like (IIA) and this it thought to be mediated by phytochromes.

Phytochromes are two identical protein molecules each conjugated to a light-absorbing molecule. What is intresting about these protiens is how the chemical structure of phytochrome is altered to its complementary form when struck by photons of the correct energy level or light.

This is really complex stuff so lets stoner frendly this info

Basicly the phytochrome molecule is the photoreceptor for red light responses. It exists in two forms, Pr and Pfr. Pr is a blue form that absorbs red light and Pfr is a blue-green form that absorbs far-red light. When these protiens are activated they cause changes in the plants mRNA thought to be controlled by horemones and causes the plant to produce flowers, Ruderalis works in a diffrent way. In the horticultural world they call these plants Day neutral plants or (DNP) for short.


This is REALLY HARD INFO SO IL EXPLAIN THE BEST I CAN. but Im no expert!!!!!!!!!!!!!!!!!!!!!!

Before I begin, Im going to post a extracted piece of info from another website:

The Flowering Hormone or Florigen (taken from Botany online)

No other botanical substance has so long and so unsuccessfully been searched for as for the flowering hormone or florigen. It did at least became a name, and its existence could be proven by grafting experiments. Phytochrome that is localized within the leaves is required for the control of flower formation. The conditioning, i.e. the signal necessary for stimulation of flowering or for suppression of flower formation is also generated within the leaves. The majority of the classic grafting experiments was performed with Nicotiana-species. Nicotiana sylvestris is a long-day plant and Nicotiana tabacum, var. Maryland Mammoth (M.M.) is a short-day plant. Most other Nicotiana tabacum-species are day-neutral.

If Nicotiana sylvestris, for example, is cultivated under short-day conditions, does it not develop flowers, but if a leaf of a Nicotiana tabacum, M.M. plant that was cultivated under short-day conditions is grafted to Nicotiana sylvestris, then it is stimulated to flower. This means that the Nicotiana tabacum, M.M.-leaf had produced a substance that was transferred to the recipient after grafting and that caused its flower formation. This proved the existence of a florigen. The opposite experiment works, too: a Nicotiana tabacum, M.M.-recipient flowers under long-day conditions under the influence of a Nicotiana sylvestris graft. Similar results are received when grafting Nicotiana sylvestris, M.M. and a species of the genus Hyoscyamus (a long-day plant). Experiments with other species from several genera yielded comparable results. All results can be combined in consistent scheme.

In summary can the following conclusions be drawn (A. LANG, MSU-DOE Plant Research Laboratory, East Lansing, 1984):

In the leaves of plants is a hormone-like substance (florigen) produced, maybe also a complex of substances, that is conducted to the shoot meristems in order to stimulate them to pass from vegetative growth to flower formation.


The florigen is not species-specific. It can be transferred to members of the same species, to members of one genus and to members of different genera. The transferability seems to be limited only by the acceptability of the graft. A good connection between the phloem of the two partners seems to be important. Grafting of monocots are very difficult to do and a florigen transfer by grafting has not been successful, but it could be shown with other techniques that it is required in monocots, too.


Florigen is physiologically not specific. It can without difficulty be exchanged between short-day, long-day and day-neutral plants. It is very likely that it is identical in all plants. The main difference between short-day and long-day plants is that the florigen production occurs only under a certain (inductive) light program, that differs in the two types.

It seems that a likewise transferable substance exists in several long-day plants that is produced under short-day conditions and suppresses flower formation. It is called antiflorigen. The reaction is weak and cannot be detected in all combinations. Florigen and antiflorigen appear to be antagonists. The flower formation is mainly based on the ratio of the two substances.

How can the combined action of florigen and phytochrome be explained? A. LANG illustrated it by the analogy of a circuit with alternative parallel connection. Accordingly has the ‘phytochrome switch’ of a long-day plant that is developing flowers to be on PFR, that of a short-day plant under the same condition on PR. In this simple way can the scheme explain the production or non-production of florigen. Both connections would have to be functional in day-neutral plants.

Now too stoner this aswell:


Basicly We dont now shit about flowering plants . But we like to guess And as the years go on we are finding out that more and more of the plants flowering cycles have to do with the genetics of the plant. My theory is that Ruderalis is producing flowering horemones as soon as it germinates. If anyone else knows more I am very intrested in this subject, and how it effects a plants DNA when reverting plants back to grow. Most growers sais they notice no apparent changes in plants that have been reverted, but there are some very weird changes going on inside the plant in flowering thought to be linked to swiches in genes controlled by horemones. And it is now being said that once swiched over the plant will always be into this so called "flower mode". Post your thoughts please !!!!

If you still awake after reading this, hope this has helped out abit.

hi guys, ive got 5 ruderalis indica seedlings in my backgarden and ive got 2 phenotypes 1 is a mutant with very thick leaves and the rest look normal i think it is northern lights out of the cross and supposedly this strain is 100 percent auto flowering so aslong as you get a nice nl pheno all should be good, ill post pics when they are a worthy size

to be honest ive pretty much gone off this strain now with lowryder being (apt mybe frm masterlow and a few other lr crosses)the highest quality autoflowerer so I was just tryin to get myself out of a rut before sept/oct but to be honest i feel like ive almost wasted my time, Even lowryder had such a high percentage of runts, it was heartbreaking...

BE AWARE THAT SENSI CHANGED THEIR PACKAGING LATE LAST YEAR.I HAVE SEEN THE SEEDS IN THE OLD PACKAGING STILL BEING SOLD IN A FEW HEAD/GROW SHOPS.(THE NEW PACKAGING IS THE BUBBLE ON CARD TYPE.EACH PACKET OF 15 SEEDS IN WHAT LOOKS LIKE A THIN PLAYING CARD CASE,THE OLD STYLE IS IN A PLASTIC CELLOPHANE PACK WITH THE STRAIN NAME ON A PIECE OF BEIGE CARD)IT STANDS TO REASON THAT THE NEWER PACKAGING HOLDS NEWER SEEDS.....TRY TO GET A HUGE DISCOUNT IF FACED WITH OLD PACKAGING

i got my ruderalis in old packaging a month ago and got 100 percent germination so i think it depends on how long/well the headshops store them
