    Thank you. Great video. This is a very simple concept actually and you very succinctly summed it up in the first 55 seconds. "Plants do not eat Blood Meal…they eat Nitrogen, Phosphorus and Potassium" …and of course to a lesser degree some dozen or so micro-nutrients. So what is the end products advantage if given bioavailable nutrients in their ionic form? Or let me ask it another way, why is this so insulting to some gardeners as if an affront to nature? Don't get me wrong, for sustainability and outdoor gardening I will always use a living soil but indoors is my house and in my house we are about maximum performance.
    Now the tricky part is satisfying the plants needs with the micronutrients in a way that promotes high sugars (efficient photosynthesis) and plenty of nutrient rich sap then I would argue, could the best of the best pallet tell the difference? You are correct, as we understand humic acids, silicates, and sea based kelp products more.
    I am using Mammoth P to boost metabolism, Z-7 microbes keep away anaerobic bacteria, RAW Full-Up Humic Acids and Honey to feed the beneficial gardening. But for the brunt of my nutrition it's agricultural powdered chemicals. Sounds horrible! Why? It's chelated micronutrients and Calcium Nitrate in a powder that when mixed with filtered water created charged ions in a solution the plant can use right away.
    So what am I doing?
    Organic or Synthetic or both?
    And will the quality still be "lesser" than organic? I do not believe so, as I think Hydroponics and Synthetic / hybrid (selective microbes) are the way of the best gardening of the future in spite of produce and the organic craze filtering into the cannabis market. Don't get me wrong I'm loving the science coming out of it, as well as the no till revolution to help in sustaining the soils of the pacific northwest. Making our footprint much less. It's great stuff but for me, a man of science unless I can see proof of an advantage with pure organics I'll stick to with the current program.

    Lots of ignorance in the comments section. The value of organic gardening is not in the source of the NPKs. The real value of organic gardening comes from the natural breakdown of organic matter by microbial life in the root zone. When microbes break down organic matter they release enzymes and acids that are beneficial to the plant, that you wouldn't otherwise get using chemical ferts. For example humic, fulvic, and amino acids which are natural chelating agents. Chemical ferts use synthetic chelating agents such as EDTA. If you look at the ingredients list on the back of your labels you'll probably see them listed there. Plants do not uptake EDTA because they are alien to the plant. Once the plant uptakes metal bound by the EDTA that EDTA will be spit back out into the nutrient solution where it will interact with another ion. One of the greatest advantages in adding a biological chelate such as high quality fulvic acid to your nutrient solution is that unlike the synthetic chelates likely present in your nutrients, the fulvic acid chain can be absorbed into the plant. This is advantageous for several reasons. The principal benefit is that the mobility of some nutrients within the plant increases. Not only does fulvic acid improve the transport of fertilizer minerals within the plant, but it also helps to transport other plant fluids more efficiently, including those responsible for terpines (smell and flavor) and resin production. The other downside to using synthetic chelates is that they break down when exposed to UV light making your nutrient solution less effective.

    What about how the both synthetic and organic fertilizers are harvested and sourced? Is there any information on that? Thank you!

    why industrial fert. mess with flavour and aroma if plants consume only the same N,P,K from different fertilizer source???

    Incredibly disappointed with the video. You'd expect that after 20 years that you would learn something about gardening. It doesn't surprise me though since our country has failed you when it comes to the education system. People can't even read, speak, or type correctly now days. You want to mix synthetic with organic? Great, feed the plants directly without feeding the microbes, then what happens to the microbes? The rhizobacteria are responsible for producing growth hormones, b-vitamines, amino acids, organic acids, siderophore, and volatile organic compounds (things you can't put in a bottle). I've been gardening for 1.5 years and I know more than your 20 years…

    Wasn't able to respond to Brad Klass comment "wow what a worthless video, actually pissed me off a little but what else can you expect from a nutrient company" as it appears he has a setting that only allows comments without being able to reply.  David Robinson aka The Garden Sage DOES NOT work for a nutrient company. He is the author of the Grower's Handbook, award winning gardener, and owns one of the busiest hydroponics stores in the world. 
    He has been immersed in the hydroponics world for over 20 years. 
    He does say there is "A lot of hype about organic". But he did not say "Don't believe the hype".  
    And even if you feel this is a bias from a nutrient company I must make you aware Green Planet Nutrients sells both products for organic gardens and a line of synthetic nutrients.  We are not trying to sway anyone into either way.  Rather informing the public so they can make better choices that suit their needs. 
    I can't respond to all your questions as I feel it would be a bit long. But David wears gloves when he works like most people would.  And we literally invade his work when we come ask him questions.  We also ask him to keep things brief so he doesn't go into too much detail on purpose as we are trying to keep them short and to the point. 
    Although people may want to be critical of leaving something out… you can always buy his book The Grower's Handbook as David goes into detail on topics much deeper. These are intended to be short on the fly videos.

    wow what a worthless video, actually pissed me off a little but what else can you expect from a nutrient company.  I would b willing to bet that this guy didn't really believe everything he was saying (maybe why he was sweating throughout whole video). if he claims to b a 'gardening sage' then everything I am about to say he probably knows.
      stating that organics r hype and that plants only need NPK!!  does this guy work for Monsanto lol?!  plants need a plethora more than just NPK to thrive.  sure NPK can grow a plant but how healthy is it?  how well does it do protecting it's self from pests and disease? how will the quality of end product b?  not good at all.  sure your yield might b way higher but at what cost?
    he fails to mention that by using organics the plant is feeding it's self and by utilizing organics there is WAAAAAAAY more things for the plant to use. meaning more tools to defend it's self, produce more flavor and smell.   When 'forcing' plants to take the synthetics (salts) we r thinking that we know more of what a plant needs than what the plant knows it needs.  r peeps really so ignorant that they think we can outperform nature?!  sorry but that is the problem, not the solution.  thinking that plants only need NPK is the type of thinking that is causing us to b so malnourished as a species.  ever asked yourself why for example wheat doesn't have near the protein it used to have before the synthetic's, why vegetables don't have near the nutrition that they used too, why we have so many sick people now compared to 100 yrs ago (even with all our new science and technology)??  it's thinking that synthetic nutrients are harmless to us and the environment that is our problem.
    and another thing, claiming that organic hydro is not attainable is absolutely false.  what he forgot to add is that along with that fish emulsion u would have to add some sort of microbe inoculant (compost tea)  to make the fish emulsion work.  with ANY organic nutrient, u MUST have microbes to eat the nutrient and then the plant feeds off of what the microbe exudes.  so yes he's right, plants don't eat blood meal, but really what was the point of stating that?!?!  why does he only mention humic acids as what breaks down organics?
    and what's with the gloves lol
    ok I'm done ranting (I never do this but couldn't help it)

    What exactly was the point of this video? Absolutely nothing was explained. "truths revealed"? No. One dudes opinion… revealed.

  • King Peezyworld 3 months ago

    Dude you are spouting non sense. Organic gardening is all about flavor and quality. Phosphorus for example is a heavy metal. The process of microbial break down of say hi phos bat guano doesn't put a chemical into the plant. It allows nature to do what nature intended. Which was never force feeding. I don't know what u smoke but I wish I could show u the difference Mr Sage.
