Three A Light: The Book That Will Help You Grow Astonishing Cannabis

Three A Light is the new, stunningly attractive book on cultivation details the straightforward techniques that can produce an astounding three pounds of indoor cannabis per light.

Sometimes an idea comes along that so completely challenges the status quo it momentarily blows your mind. The groundbreaking book Three A Light does just that with its extreme approach to pruning that gobsmacks most growers.

“I’ve converted guys who’ve been growing for 40 years,” says expert grower and author Joshua Haupt about his vanguard cultivation methods. “People are hesitant to the process at first, saying things like ‘Did you really mean to do that?’ But they soon come around.”

It’s a familiar refrain from cannabis growers who open the book and leaf through the pioneering (and at times shocking) methods employed by Haupt to attain the Holy Grail of weed cultivation – 3 pounds of killer cannabis grown under one sodium light. But before growers can enter the promised land, they’ll have to place their faith wholly in the hands of Haupt.

To offer some perspective on how extraordinarily far out his 3-pound declaration is, consider that for years an acceptable yield of cannabis produced under one high-intensity lamp was somewhere in the neighborhood of 1-1.5 pounds per grow light.

In fact, most cultivators would be dancing around the grow room if they could consistently hit 1.5 pounds of indoor-quality cannabis per light. So the doubling or tripling increase in yield that Haupt is suggesting is a quantum leap forward for growers.

Three Pounds a Plant
Haupt, 30, who was diagnosed with epilepsy as a teenager and uses cannabis for his condition as an alternative to pharmaceuticals, says it all started with a tiny plant he cultivated in his backyard.

“I began growing cannabis when I was 15 years old with a few Mexican seeds,” he says. “Since I was in charge of caring for the vegetable garden at our house, I thought I’d throw [the seeds] in to see how they did. They did great and by the time my parents had noticed what I was up to, they thought the plants were too pretty to kill.”

The main method that Haupt employs to ramp up flower growth – a technique he calls “Schwazzing,” which he learned from mentors over the years – includes heavy pruning at key times during the first 20 days of flowering growth. The resultant view of the garden at the end of those three weeks is astonishing. Where most growers would expect to see a big, beautiful “screen of green” canopy, Haupt trains his plants to grow more vigorously by cutting them back to literal nubs.

Haupt points out that marijuana fan leaves act as small sugar factories that feed the flower. Remove those leaves and supplement the plant with micro- and macro-nutrients through a special feeding schedule, and much of the new energy travels right up into the building of mammoth buds. Cutting back fan leaves also provides optimal light penetration, which means even more accelerated growth.

The particular photos that stun growers are about a quarter of the way through the 215-page book: shots, before and after, of a room that’s just been flipped into the flowering stage. One photo shows a pretty, lush garden of about 50 adolescent plants basking in the warm glow of sodium lights. The other photo shows that same room post-Schwazzing – a frightening view like the aftermath of an errant weed-whacker attack.

Haupt has heard all the bewildered comments. That’s why the only content on page 55 reads reassuringly in large typeface: “Don’t be alarmed. Your plants will bounce back quickly with our feed schedule. Shocking them will only make them stronger in the long run.”

One of the key aspects of his Schwazzing method is the nutrient schedule that the cultivator has developed over more than a decade of growing cannabis. His Success line of nutrients breaks down exact amounts at exact times in a direct, no-nonsense manner.

That is really the beauty of Haupt’s Three A Light – his writing is straightforward and made with a beginner audience in mind. He doesn’t bog down pages with scientific jargon that might confuse or distract readers. His growing procedures are offered in a step-by-step fashion with large, clear photos and a scaled-back style accessible to all levels. And he wraps the whole shebang in an elegant package with beautiful photography and clean design.

Says Haupt, “Think as user-friendly as an Apple product but with a Louis Vuitton feel.”

And the luxury price tag of $500 per book, how does he justify that?

“Most growers wouldn’t bat an eye at a new light costing $500 or a new line of nutrients for $800,” says Haupt. “To most growers, that knowledge is worth much more than $500 – not to mention when you take two seconds to do the math on what Three A Light truly means for your harvests!”

After making that comment, Haupt’s phone rings – it’s a recent buyer of the book calling for user support. Imagine that, calling a customer care line and instead of reaching some outsourced voice in a faraway cubicle, you get the author himself walking you through your issue.

“Sorry, I’ve gotta take this,” he says politely excusing himself. “This is what it’s about, giving customers value and getting everyone producing like we know they can.”

    Its called ECONOMICS all you idiots hating on a guy for selling a book, wtf? If you don’t like it, don’t buy it! $500 is nothing if you double your yield. You make more than $500 on one single plant! I just met a guy this evening in Denver who told me about “THREE A LIGHT” and I don’t know if I will spend the $500 but I sure do have an open mind to it….
    Anyway, this old dog would love some new tricks, you wanna bees can just keep hating, I will be growing lol….

    The stripping of fan leaves pre flowering and on day 21 has been done since before 2008 in CO Springs. I have pics of that as well as doing it on a horizontal table. We just called it growing only buds. The idea was to maximize the footprint of light with just buds. We never had stressed plants or herms. It was even done in Rockwool and the branches were tied down. Congrats on a book but it’s not a new method. And with the right strains, environmentals, and pruning, trimming care, and complete major,secondary, and micro nutes at right times people are nailing 3 1/2 to 3 3/4 lb now. Won’t be long and it will be 4….

    Yo $500 for a book, no one has fact checked? Someone’s opinions on growing? This is not what the industry is about. You want the community to prosper and more people to benefit from Cannabis like he does, don’t try and charge people $500 to tell them to defoliate. Up the sugars and wait. This is an embarrassment. Straight up. No, growers do not bat and eye lid at $500 for a new light, but a book claiming to turn your one light into a magic machine and suddenly you’ll be pulling down 3 plates per plant. No.

    Fuck this bullshit

    I grow in Pro-mix, Vertical Sodium. 30 gallons. Defoliate the plants at day one, five and ten of flower. Then day 20. End of story. He is not telling anyone shit that isn’t already known. Do not pay $500 for someone’s opinions
    Remember opinions are like assholes and this was just mine

      I would agree with you normally, on every aspect, but I used to snowboard with Moona [Josh] and have seen his grow rooms first hand. We both had GSC from clone and OG 18 from seed in our own respective rooms, plant to harvest ratio for me was just over 1 per plant and he more than doubled my total. And Moona’s nugs were a lot denser and filled out a shitload more than mine. This was in 2011 in Summit County Co, I’m in Cali now managing a large scale indoor & dep operation and I teach this technique to every growing I employ, and I literally just learned about this book last nite. Seriously, it’s oct 17th 2017 at 6:50 am, and last nite my roommate showed me the website when i got home after spraying and I put 2 & 2 together. Can’t speak for the price tag, but the technique and the feeding work, I promise..

    Looks like regs to me…with nute and pH issues or disease.

    All yield genetics, which would be fine if the min THC is 18%.

    peeps do realize that many people can get 3 pounds per light. just a way to make sense of things friend who grew vertically had precise supervision of grow did 3 pounds off a 600w gavita single ended….its not nutrients or lights alone, but AS ALWAYS just a decent enough combo or recipe of everything combined. also have peeps who grow organically living soil no till nothing but water and can get 3 p’s per light killing what most would sell in a dispensary…PROPAGANDA 1 p per light is mostly terrible. ‘specially for a 1000w light. i guess just have a ton of caveman growers. just did a vertical with gavita flex @825 w/ philips greenpower bulb and yielded 2p,2oz and yet there were many things that went wrong with that round.
