In this video, Ethan Walter with Bright Agrotech explains the basics of N-P-K. NPK stands for nitrogen, phosphorus, and potassium. These three numbers represent the ratio of N, P, and K in your fertilizer. Every main mix (complete balance) fertilizer will have these numbers clearly displayed, always in the same order. Not all fertilizers are complete balanced fertilizers, however. Different ratios of NPK serve different needs. For instance, a blooming mix might have low to no nitrogen in the mix. So what do each of these nutrients do? Nitrogen is what makes your plants green, big, and strong. It is the absolute most important nutrient in the solution. Phosphorus is important for blooming; it plays a role in all of the reproductive roles of your plant. Potassium is important to plant photosynthesis, CO2 uptake, activation of plant enzymes, and water uptake. It is important for building strong stems and seeds. N, P, and K are not the only nutrient that your plant needs. Micronutrients are required in much smaller quantities. A complete and balanced fertilizer will almost always include the micronutrients. The NPK in your fertilizer are not present in their pure elemental form. Plants can only take up certain compounds with these nutrients in them. Fertilizers also sometimes have multiple forms in the fertilizers. These are listed on the label of the formula. Many sources of fertilizers are synthetically derived. You might be wondering if there’s an organic option. The answer is yes, but realize that more is needed to use an organic solution. To use organic fertilizers in a hydroponic setup, you need a very strong microbial community in your system. The microbes are what drives organic growing. They cycle the nutrients and turn them into a form that the plants can use. So if you don’t have […]

    @Hydroponics4Dummies What's the deal with all the "hydroponics starter kit" spam?

  • murissan 1 week ago

    @HerbalixPro What hydroponic starter kits?

  • growerman42 1 week ago

    @boombaklot don't know what you're talking about.

    Iguana Juice is the only organic that's actually clean enough to run in hydroponics. It doesn't clog, that's what makes it different.

  • boombaklot 1 week ago

    works good though just to thick and stinky for hydro but works great now that i am back in soil

  • boombaklot 1 week ago

    dont use iguana juice in aeroponic/bubbleponic systems, i used it in an bubbleponic system and it clogged up my air stones, also smells like shit lol

  • StanwoodSpartans 1 week ago

    Iguana juice contains b vitamins

  • Sorry Stephen mate, how come you talk with an american accent now anyway?

  • hugetom80s 1 week ago

    I didn't know it had become cool to make fun of people who talk differently than you do.

    How very enlightened of you.

    If we looked for your other comments would we find you making funny of the swollen bellies those silly starving African kids have? Perhaps in your spare time you can go play catch with some coma patients.

    That'd be a hoot, wouldn't it?

  • I didn't know Stephen Hawkings was doing voice overs now.

  • veggedout 1 week ago

    sounds cool
    ima have to ask my guy bout this

  • Kultiv8or 1 week ago

    I'm building a DWC setup just to try this stuff out. I got so many people asking me if I've got organic produce that I just can't ignore it anymore. There's some serious bucks in that organics craze.

  • hugetom80s 1 week ago

    Yeah, let's all make fun of the guy who talks different. Won't that be a hoot.

    Jeez man, get a life.
