Best guess is being used to and getting along with (assuming she ever did that is), weed that is/was high in Indica genetic heritage. There are three main species in the genus Cannabis. C.sativa, C.indica and C.ruderalis.
Purestrain Sativas produce mostly THC and lesser quantities of CBD (just considering THC and CBD ratios here, there are HUNDREDS of phytocannabinoids) whilst pure Indica parentage leads to a much higher CBD to THC ratio. It of course varies according to the strain chosen to grow, the manner in which it is grown, the skill of the grower, soil (if soil is used rather than hydroponics or aeroponic methods of growing our wee babies) quality, and the lights available, plus of course, growth setup and fertilizers, trace nutrients etc.)
C.ruderalis on the other hand, originates from the russian steppes, and produces in and of itself relatively little in the way of psychoactive phytocannabinoids. Not to say its absent, just cannot compare with either of the other two species.
All three are capable of interspecific hybridization, and accordingly, crossbreeding has become quite an art amongst enthusiasts.
Where C.ruderalis shines however, is that unlike either Cannabis sativa, or C.indica, C.ruderalis autoflowers, that is to say, it does not require timing of light cycles for indoor grows. So a percentage of Ruderalis genetic material in hybrids, results, ideally in an autoflowering strain.
The growth habitat of C.sativa is tall, very tall compared to the other two, C.indica is squatter and bushier, making it better suited for outdoor grows than C.sativa if concealment is desired. C.ruderalis is the shortest of all three species within the genus Cannabis, and a crossbreed between an Indica and a Ruderalis can result in a short, stocky and strong compact bushy girl that doesn't need any attention paid to fucking around with cycling the right amount of the right kinds of light at the correct time. Just hit it with what you can throw at it, and it will flower.
(I say 'girl' because its the female that produces the goods, males plants are good only either for breeding stock, or if in bulk, for chemical extraction and processing for what THC/CBD/CBV content there is. The good stuff is to be found most of all in the female flowering tops, and the highest quality skunk, aka 'sensimilla' meaning 'without seeds', is to be harvested from females which have never been pollinated. So unless breeding, its best practice to identify and destroy male plants before chance for pollination has occurred via examination of the flowers under a microscope, or hand lens/magnifying glass. Either toss them out with any other males into an extraction, or weed them out (see what I did there:autism:) and kill them unless they are to be incorporated into a hybridization program.
Otherwise, they aren't much good to anyone. Although they could of course always be say, kept elsewhere in an outbuilding, and the (grower's) body carefully sterilized after exiting same, in order to glean every last scrap of THC/THV and CBD goodies that can be obtained.
Its indica weed or if not purestrain indicas, that are usually used for making hash, sativas tend to be speedy, more hallucinogenic and trippy, far out, zingy stuff, sometimes anxiogenic in excess (think pulling a whitey. Sativas are better at making that happen than indicas) whilst indica smokes tend to be really strongly muscle-relaxant, analgesic and anti-inflammatory, and give rise to what is commonly and fondly known as 'couch-lock' weed. So called, because it'll lock you to your couch, lazily sprawled out and for the life of you cannae' be fucked moving, kind of stuff. Dreamy and hypnotic rather than zingy and trippy, about sums up indica vs sativa.
Of course, hybrids vary massively, depending on parentage and contribution of their parents and further ancestors down the 'blood'line. Never tried smoking a purestrain Ruderalis, but can testify to the excellent breeding qualities of the hybrids, grown properly, with the right ancestry (the plant, not the grower:P) a strong indica with potential, with just a bit of Ruderalis genetics mixed in, a couple of feet in height, but bushy and compact with giant, rich and flavorsome colas can be had. Have even....ahem....observed the growth of....a mostly indica, with a wee bit of sativa and some ruderalis hybrid that even considering the Sativa genetic material present, stayed at about perhaps 1.25-1.35-1.4 feet tall, but fat and bushy and oh so delectably scented.
No fancy light schedules, no timer switch wiring was needed, just a growth chamber connected to an activated charcoal scrubber to filter out (regrettably, and of course, sadly, mandatorily for practical reasons) that delicious sweet-spicy fragrance before it exits and diffuses into the atmosphere of the growth building, fans to push air into same and replace old, oxygenated air with fresh CO2-laden air.
I've often wondered how it would enhance, if one were to take a few batches of identical plants, using tissue cloning in vitro from the same female plant, so as to eliminate utterly any variation caused by the plant, and keep alll other variables identical, lights, light schedule if required, temperature, water quantity and schedule of administration, fertilizer type, quantity, dilution and timing etc. and vary only the quantity of CO2 in the air. Enriching it with a canister of CO2 (these are available cheaply for welding, from such stores. They do not cost much, IIRC, less than the £11-12ish I pay for my argon tanks for when I need an inert atmosphere) and do a comparative study upon say, 8-10 batches of say, 6 plants each, with identical conditions, and afterwards, extraction of identical weight of rapidly chemically dessicated herb, kept cold, to avoid as much evaporation of the terpenes that give the goodies their delicious scents and flavours, by say, storage over anhydrous calcium chloride in a dessicator, kept in a coolant bath. When totally dry to take H2O content out of the equation and simplify calculations (I suck at those and I hate doing them too. Dyscalculia blows theresa may manure. then do a careful exhaustive extraction via soxhlet using liquid butane or a mixture of butane and dimethyl ether then compare the yield and percentages of otherwise identical plant clones, grown in exactly the same conditions, with various different levels of CO2 addition (and even subtraction) to determine the absolute optimum concentration range. Of course, that would be the first experiment. It would of course require repetition with clones from other plants, other hybrids and gene-stock, to determine the statistical mode of yield regardless of parentage, and thus optimum concentration of additional CO2 to be introduced to the inlet by which fresh air enters the growth chambers.
