For more than half a century, cannabis cultivation has relied on a simple, widely accepted convention: the 12–12 light cycle, which means 12 hours of light followed by 12 hours of darkness to trigger flowering. It became standard not because growers were wrong or uncurious, but because it worked reliably, it fit human schedules, and it was passed from one generation of cultivators to the next as practical wisdom.
Over time, this routine gained the weight of tradition, treated almost as a biological rule rather than a human-made guideline.
In Argentina, a community of growers and researchers led by programmer-turned-botanist Iván decided to challenge that assumption by running “supercycle” experiments that stretch the day beyond 24 hours and force the plant to reveal how its internal rhythms really work.
Their results, plants flowering under 13–13, 16–16, and other extended cycles, raise a radical possibility for the cannabis world and for indoor agriculture as a whole: “what if the plant’s clock isn’t fixed at all?”
The work is ongoing and largely crowdsourced, but its early results are already challenging some of cannabis cultivation’s oldest assumptions.
From HTML to DNA
In its earliest sense, “hack” meant a clever workaround, a shortcut that solved a technical problem through ingenuity rather than obedience. There is something about hacking code and computer systems. When what was engineered to operate within strict parameters suddenly becomes reconfigured, power dynamics shift, functions mutate, and new processes emerge.
The meaning of hacking evolved, gaining weight and politics. Hacking became a form of dissent, a refusal to accept hierarchies, defaults, or the systems that pretend to be immutable.
And that’s exactly where Ivan’s story begins: inside a hacker community during Buenos Aires’ democratic spring in the late 1980s.
What began as over-the-phone intrusions, BBS experiments, and the thrill of breaking digital locks would, decades later, become a new kind of hacking: reprogramming cannabis light cycles and plant behavior. From HTML to DNA.
The Argentine software programmer, cannabis grower, and researcher remembers those early days as “a way of seeing things.” “You’d look at a system, see how secure it was, and break it just to see what was inside,” Ivan told High Times, from a basement data center that was recently retrofitted into an indoor experimental station.
The instinct hasn’t changed, and in 2025, the system Ivan probes, breaks, and rebuilds isn’t a server. It’s the circadian logic of a plant.
The what?
Plants, like humans, run on internal clocks. A circadian cycle is the biological rhythm that tells an organism when to grow, rest, flower, and conserve energy.
It responds to light and darkness, but it is not a simple on-off switch. It’s a whole choreography of hormones, enzymes, and signals that evolved long before clocks, calendars, or grow tents existed.
Yet, modern cannabis cultivation has treated this rhythm as if it were static, universal, untouchable. The industry’s consensus, almost a commandment, is the 12–12 light cycle for flowering, and that is exactly what Ivan and his community decided to hack.
Instead of accepting 12–12 as nature’s law, they went after it the same way he once went after secure servers: by pushing, stressing, and bending the system to see what breaks, what holds, and what transforms.
They asked a simple but disruptive question: what if the plant’s clock isn’t fixed at all?
The Cannabis Supercycle
When Ivan looked at the 12–12 flowering cycle, he saw not a biological requirement but a cultural inheritance. Growers kept trying to optimize within that frame, adding supplements, adjusting environments, without ever asking why 12–12 became the rule in the first place.
As he puts it, “Why do we spend so much time trying to improve flowering under 12–12 when we don’t even know why we chose it? Why do we treat twelve hours of light as if it were some kind of divine law?”
For him, that unquestioned consensus was the real vulnerability in the system, the part worth probing. Once he stepped outside that frame, he found an even deeper contradiction: the idea of a fixed day length is an illusion.
Ivan pointed out that when the earliest plants appeared, Earth’s rotation produced 22-hour days, and through geological time, the planet has been slowing down. Dinosaurs lived under 23-hour days; we live under 24; future organisms may evolve under 26.
In other words, time, at least as a biological environment, has always been a moving target.
“Biologically, time is unreal,” Ivan said, speaking less as a philosopher than as an experimental grower. What growers call a “natural” 12–12 cycle is not nature’s law but a human convenience.
By manipulating light cycles beyond 24 hours, he argues, indoor cultivation can explore evolutionary pathways the plant has never seen, rather than imprisoning it in a schedule humanity invented for its own comfort.
One of the first shocks growers face when experimenting with supercycles is how quickly the day “slips.” A room that turns on at 9 a.m. one day might switch on at 11 the next, and at 1 p.m. the day after that. It’s inconvenient for humans, but far more natural for the plant.
Ivan pointed out that 12–12 became the norm not because cannabis needs it, but because people do. “We adapted to 12–12 because we function in 12–12,” he says. It matches office hours, daily routines, and the artificial schedules society built for itself.
Plants, however, have no allegiance to that clock. Their biological time is fluid, always evolving, and the supercycle experiments aim to explore how cannabis behaves when freed from the constraints of a human workday rather than a real, biological necessity.
Ivan and Alien, his partner in cannabis research, had been replicating a Canadian study showing that 13–11 light cycles could boost production. Their hacker instinct pushed them further. If 13–11 worked, why not try 14–10, or throw infrared into the mix?
When 14–10 stalled in a semi-vegetative limbo, a friend asked the question that changed everything: “Why do you use a 24-hour timer?” Ivan realized a standard timer would not allow anything beyond a 24-hour day. So he hacked the problem.
He grabbed a WiFi timer, rewrote the schedule, and programmed a 17–13 cycle using what he calls a buffer overflow, the same technique hackers use when they overload a variable to force a system to execute unexpected code.
“We basically gave the plant more hours of light than a day has ever had,” he explained. “And the plants flowered. 17–13 worked.” What started as a joke became the moment they understood the rules were not biological but technical.
They pushed further. Some plants needed longer nights. Others exploded under extended days. They tested strawberries, calendulas, cherry tomatoes, and flowers, and all showed signs of hyperproduction.
Today, more than 2,000 people are registered on their site, with roughly 300 actively running experiments. About 700 plants have already been chemically induced into polyploids as part of parallel breeding experiments.
What began as a workaround after a police raid became a decentralized research cluster, a swarm of small grows acting like a single supercomputer.
“This is going to change it all,” Ivan concluded. “It’s going to be a mess, but it’s going to change everything.”
If he’s right, the most radical shift in modern cannabis cultivation may come not from genetics or nutrients, but from redefining what a “day” actually is.
