I’ve been working on an experiment comparing water soluble fertilizers for hydroponic growing. Here is how it began: http://youtu.be/oeLd2SP0c6U The final results are in. When it comes to hydroponics, Miracle Grow is not recommended because it has a form of nitrogen that is best suited for use in the soil. It does poorly in a hydro application. The 4-18-38 hydroponic fertilizer that I have been using for awhile now absolutely kicks butt. My recommendation for anyone wanting to grow hydroponic vegetables is this: find a true hydroponic fertilizer to use, and leave the Miracle Grow products for the soil. The results speak for themselves. My new facebook page: https://www.facebook.com/mhp.gardener I show you how to make a simple Kratky container to grow a tomato plant. We also try it in a traditional garden and an NFT system. I usually grow just leafy greens but people have been asking me about other veggies. Going to give this a try. I have a small eBook to help beginners. This helps me to continue to make content for this channel. https://www.etsy.com/listing/615008659/keep-on-growin-ebook?ref=listing_published_alert Marty’s Garden https://www.youtube.com/channel/UCnPkv-JUX4Pqn_LYbykzAtw Pepe Fassos https://www.youtube.com/channel/UCxavi8NUigf45LYtm9ViKmw Hydroponic Gardening & More with Brent https://www.youtube.com/channel/UC_OWzdAbv5ubnEI7D2BAe5A Video Rating: / 5 Related PostsOrganic Hydroponic Fertilizer Experiment Nov 2013Failed Again – Organic Hydroponic Fertilizer ExperimentPee Pee-ponics experiment results- hydroponics without the chemicals, aquaponics without the fish.Hydroponic Vs Soil Experiment – 6 Weeks Growth ComparisonHydroponic Fertilizer : What I Use & How to Mix ItHydroponic Tomatoes – The Results of the Wetpot and Anovapot Systems

    Hello mhpgardener, I've watched a couple of your videos and I enjoyed them. I am very focused on hydroponics nutrition. What other hydroponic fertilizers do you know or would recommend for great yields and overall plant health. Also, did you engage in foliar feeding?

  • Matt Jimenez 2 weeks ago

    First one had some clean looking water – the others, not so much. Sold out to master blend / chem grow?

  • Craig Reid 2 weeks ago

    did you use just master blend or did you make the mix from your fertilizer video with calcium nitrate and epsom salt?

  • Tvzblaze Ggg 2 weeks ago

    jack's does make a hydroponic fertilizer

    the problem with these is a lack of micro nutrients, not just cal and mag.
    i like maxi bloom or maxi grow from general kydroponics

    my masterblend is 4-12-25 ad said it was was 4-18-38

  • Jahedur Rahman 2 weeks ago

    WHERE TO GET THE MASTERBLEND MIX FROM:

    You can get the Masterblend 4-18-38 Hydropronic Mix from the following stores in the US. I could not find any retailers in Europe/UK. The only company that does worldwide shipping with great communication and service was Custom Hydronutrients.

    Morgan County Seeds, Missouri (customer service is terrible)
    Custom Hydronutrients, Missouri (customer service is brilliant)
    Power Grow Systems, Utah (have never tried)

    WHAT TO ORDER:

    Order the following items for perfect blend.

    Masterblend Fertilizer 4-18-38
    Calcium Nitrate 15.5-0-0
    Magnesium Sulfate (Epsom Salt)

    **IMPORTANT! Do not mix the 3 components together! Doing so will cause nutrient lockout and all the nutrients will not be available to your plants. You can mix the MasterBlend and Epsom Salts together, but not the Calcium Nitrate! Wait until both are completely dissolved in warm water. Ideally you should mix each component separately in hot/warm water until thoroughly dissolved before mixing the next component. DO NOT BUY KITS THAT ARE PREMIXED!

    WHAT TO MIX:

    1 Gallon Recipe:
    2.4 grams MasterBlend 4-18-38 2.4 grams
    Calcium Nitrate 15.5-0-0 1.2 grams
    Magnesium Sulfate (Epsom Salt)

    5 Gallon Recipe: (Classic Masterblend mix)
    12 grams MasterBlend 4-18-38 12 grams
    Calcium Nitrate 15.5-0-0 6 grams
    Magnesium Sulfate (Epsom Salt)

    You're welcome

  • Cw Pemberton 2 weeks ago

    how does it taste as compared to the garden.

  • DiveCrewCanada 2 weeks ago

    Would it be possible that the Miracle Grow problem resides in possibly the fact that it doesn't remain in suspension in the water? I would be curious to hear at how it fares in a circulating system if anyone had tried?

  • MyOtherNewName 2 weeks ago

    I do t know anything about nutrients, and am a beginner. I just built a A-Frame NFT system, Got my seeds started and went to the Hydro store. They sold me a Botanicare CNS17 Grow 3-1-2. Is this wrong? All help is appreciated.

    Note: I'm trying to grow lettuce and other type greens.

    I am so thrilled and excited to get started in hydroponic gardening and I couldn't have chosen a better teacher than you to learn from!! Thank you for sharing your knowledge; a very selfless contribution to our needy planet. I will keep you apprised of my success, positive thinking due to your help.

    New sub I liked your video. I use the Kratky system too 🙂 I can't wait to see how these 3 differ in growth 🙂 Thank you so much for sharing 🙂

  • martysgarden 2 weeks ago

    I would give my expertise on the look of these, and say that they are indeterminate. They will still throw side shoot suckers that you can use as cuttings.
    Loving my Bok Choy here,,had some Baby leaf in my noodles today,,,
    Looking forward to more vids and whatever you throw at us.
    All the best
    Marty
    ps: I haven't seen you grow any Khangkong yet,,you got some growing Mike? It would be a perfect plant for your setup.

  • GippslandBirds 2 weeks ago

    do you have a system for checking the water level in your downpipe planters or do you just remove a plant to see?

  • gigharbourite 2 weeks ago

    I'm watching you on my TV, so much better! I can see all the detail. everybody should watch on your TV with the YouTube App.
