Actually he was the one who created it in the 70's. He later became famous in a different way by opening "Mellow Yellow" Amsterdam's 1st coffee shop.
So, now you know, too.
Good job Sam,
“The indoor revolution in cannabis cultivation begins in earnest in the early 1980s with the embrace of hydroponics as a primary growing medium. First developed in the 17th century, ‘hydro’-grown plants proved that non-soil mediums sustain full plant development. Later on, German scientists focused on the necessary nutrients in water solutions that can largely replace soil and found such in three: nitrogen, phosphorus, and potassium (NPK). The invention of both drip irrigation and the nutrient film technique (NFT) in the 1960s creates an obvious appeal to some of the earliest indoor cannabis cultivators.
According to
High Times cultivation editor Danny Danko, “a combination of factors including Nixon’s 1969 crackdown on the Mexican border, Carter’s paraquat spraying, and the advent of powerful HID (High Intensity Discharge) indoor grow lighting made hydroponic marijuana growing increasingly intriguing, attractive, and possible. Soon, companies sprang up to service the needs of those growing with the increasingly more complicated hydro systems.”
In a pre-internet world, via a once-revolutionary technology – the printed press – all of this new information and cultivation jargon was largely propagated by just a few magazines and book authors, notably the long-surviving High Times magazine, the short-lived Sensimilla Tips magazine, and cannabis cultivation writers Mel Frank, Jorge Cervantes, Ed Rosenthal, Kyle Kushman, and Danny Danko.
For non-sophisticated cannabis cultivators, one of the first major public forays into the subject matter of growing cannabis hydroponically was published in the July 1982 edition of
High Times (‘Do it Yourself Hydroponics’); in the May 1995 edition of
High Times, ‘The Great Hydro vs. Bio Debate’ was featured amongst prominent American and Dutch cannabis cultivation experts.
The influence of Dutch cultivators and seed breeders on the evolution of indoor cannabis cultivation can’t be understated. The Dutch have always been prolific and efficient farmers, dominating markets around the world with their floral exports. Since the late 1970s, Dutch governments have carved out Europe’s most tolerant and pragmatic cannabis laws during a time of worldwide cannabis prohibition by allowing the establishment of hundreds of so-called ‘coffee shops’ to sell cannabis and hash products to adults. In the early years of the coffee shops, cannabis products were largely smuggled from North Africa and the Middle East (i.e., Morocco, Tunisia, Lebanon, etc). Untenable for the long run, cannabis supplies by necessity in The Netherlands needed to be produced locally, and therein a quasi-legal indoor cannabis industry was first realized.
Dozens of innovations for improving indoor cultivation have been championed by the Dutch in the areas of hydroponics, cloning, seed breeding, growing mediums (i.e., rockwool), soil, nutrients, CO2 infusion, and smell mitigation.
Hydroponic gardening’s acceptance among elite cannabis cultivators is showcased in a deeply researched
New York Times Magazine piece from 1995 by bestselling author Michael Pollan, which highlighted the Dutch’s prominence and significance in cannabis cultivation’s embrace of technology—including profiling an American cannabis cultivator who “tended” his hydro garden remotely to avoid detection by employing computers, software, and modems.
Unlike outdoor cannabis that needs little more than sun, water, and nutrients, indoor cannabis requires numerous other factors that have come to increasingly rely on ever-evolving and improving technologies to maximize yield, minimize cultivation time, and secure against encroachment.
The evolution of cannabis cultivation indoors from fluorescent to a family of high-intensity discharge lights is a remarkably short one at barely forty years. There are competing and compelling reasons why cannabis cultivators may choose to use one form of lighting over another: crop yield, energy efficiency, and plant quality. The popular range of HID wattages are from 150 for a small personal indoor garden to 1100 for commercial growing with lumens-per-watt efficiency, spectral balance, and brilliance providing the data points to measure a garden’s overall light efficiency.
Measure? Most cannabis cultivators, notably indoor growers, possess a plethora of electronic meters to measure a myriad of necessary conditions in an attempt to maximize their crop’s output: air (humidity), lights (lumens), soil, temperature, water, and nutrient content.”
i was mostly on icmag, a little rollitup and thcfarmer etc.
