Can you foliar spray carbs for better marijuana?

In the grueling sport of marijuana growing, it's interesting to know that marijuana responds to extra carbohydrates and amino acids the same way endurance athletes respond: marijuana scientists have discovered that your hydroponics plants have more energy, vigor and yield when you feed them carbohydrates, vitamins and amino acids through their roots.
In the good ol' days of Colombian Gold that sold in the USA for $20 an ounce, Colombian farmers poured sugar, vanilla, cinnamon or molasses into their marijuana root zone, hoping to sweeten their crops.
Nowadays, your hydroponics store offers formulas that contain carbohdyrates. Some are said to boost plant energy. Others are said to boost bud taste and aroma.
One product that growers'll tell you to avoid is Brix Plus. Its maker recommends spraying it on your crops a few days before harvest. Some people use it after harvest. It's supposed to add weight and make crappy weed taste better. What it really does is clog leaf openings (stomata) that your marijuana plants breathe through. Dealers use it to pad their weed weight. It sucks.
Because marijuana growers desire to enhance bud size, taste, aroma, and potency, you see several products advertised as containing "carbohydrates" that boost yields and other bud traits.
But how accurate is this information, and what if any product actually makes your buds taste, smell and grow better?
To answer these important questions, we first look at an article about spraying carbohydrates on plants. The article is in the December, 2010 issue of Maximum Yield hydroponics magazine; it's authored by "Craig Gribble."
Gribble's article, titled Plant Potential: Maximum Growth Through Foliar Feeding, claims that foliar feeding carbohydrates is far better than root feeding.
It's a very surprising claim. We all know plants evolved to take water and nutrition in through their roots, and that the only inputs our plants evolved to take in through their leaves are light and C02.
So why would Craig Gribble tell us otherwise? Perhaps Gribble believes what he is saying, but I wonder if there's more to it: Maximum Yield lists Craig Gribble as author of the article, without telling you that he's also a leading official with Dutch Master, a hydroponics company that makes foliar spray products!
Their product names are cool (Liquid Light, Saturator, etc.), but Dutch Master provides only a few tidbits of information about their stuff, with not enough detail to prove how or whether their foliar products even work.
Old Information Versus Marijuana Research
While I was studying the Dutch Master website and plant science studies trying to figure out if Dutch Master was legit, I noticed the opening sentences of Gribble’s Maximum Yield article are word for word the exact same as the opening paragraphs of an advertising blurb on the Dutch Master website.
What's more, Gribble's article and website mentions the research of "Dr. H.B. Tukey" to assert that foliar feeding is amazingly effective- but fails to mention that Tukey’s research was conducted more than 50 years ago on non-marijuana crops, and has been superseded by marijuana-specific research.
Gribble wants you to believe that hydroponics marijuana roots do not uptake carbohydrates, amino acids and other non-nutrient substances. But rest assured- marijuana roots are capable of uptaking carbohydrates, amino acids, nutrients and other substances. Read this scientific report to get more info on that.
Also know that foliar spraying is useful in certain circumstances, like when your hydroponics marijuana plants have root problems and you need to attempt to deliver nutrients through leaves.
Notice I use the term “foliar spraying” rather than "foliar feeding," because many of the benefits are protective rather than nutritional. For example, I foliar spray beneficial microbes and potassium silicate on my early-phase crops, because this helps defeat molds, mildews, and pests such as spider mites.
Here's a basic but crucial foliar spraying tip: if you want hydroponics nutrients foliar spraying to be at all effective, you need to use an organic or synthetic "surfactant" that helps leaves absorb what you're spraying. Just realize that some portion of what you spray on your crops is likely to be on them as residue when you harvest, especially if you spray during late bloom phase.
Unless you're dealing with an emergency situation that absolutely requires foliar spraying, avoid foliar spraying after your marijuana plants have set flowers. It ruins the taste of your crops, and can create health problems for anyone who smokes your bud.
Marijuana That Tastes Like Cannabis Candy
In direct contrast to Gribble's foliar feeding beliefs are the approaches common to the rest of the hydroponics industry, which recognizes that roots are the primary feed mechanisms for your plants.
Old school growers still use molasses and other crude materials as root feeds, but those methods create root zone problems and other hardships.
It's easier to use something like Bud Candy, a marijuana-engineered carbo booster that provides a unique blend of complex carbohydrates and proprietary materials that infuse into your plants via roots to boost the scent, taste, size and potency of your buds. It also provides your blooming hydroponics marijuana plants extra energy at a time when they're running out of energy due to intense metabolic demands...and it feeds beneficial root zone microbes that increase yield and protect your roots.
You've likely noticed that your plants go into a mid-bloom slump. That's because they're having a hard time manufacturing energy for themselves. Bud Candy gives them an easy supplementation of energy that they use for unusually bountiful bud production.
The good news is that root-feeding the right types of carbos and other booster materials to your hydroponics marijuana plants during bloom phase gives them the extra energy they need to produce bigger, more resinous buds. It also boosts taste and aroma.
Marijuana Grow Guru Jorge Cervantes Agrees
The basic fact about feeding carbohydrates, as you see in this video by marijuana grow guru Jorge Cervantes (if YouTube has made it private, it's a good idea to buy the Jorge Cervantes DVD), is that your plants' roots are the intake engine for nutritional elements, carbohydrates and other substances necessary for growth and yield. Not your plants' leaves!
Beyond the fact that Gribble disses your marijuana's roots, it also reveals a crucial difference between Big Buds and Maximum Yield. It's important for our marijuana community to know the difference between the agendas and quality of information provided by these two major hydroponics publications.
In Maximum Yield magazine and at its indoor gardening expo events, nobody is allowed to mention marijuana, which makes it very hard to have a useful marijuana cultivation discussion!
In stark contrast to this no-marijuana approach, Big Buds gives you tools, techniques, and tactics for growing heavyweight buds sticky with THC.
I write for Big Buds because I want you to grow your dankest, most valuable buds ever!! But Maximum Yield, Craig Gribble and Dutch Master can never tell you how to get the dankest, kindest buds from your marijuana. It's their big taboo.
For sure this is why marijuana growers turn to Big Buds instead of Maximum Yield. And yeah, your plants want to be fed primarily through their roots. That's why Gribble's foliar-loving advice is just not good for you or your buds.
