    Difference Between Canna Mag(mgo) & Epsom Salt(7h2o)

    cana mono magnesium is epsom salt in water. In some countries, other than the USA, the fertilizer label guaranteed analysis for magnesium, calcium sulfur ect have to be listed as the oxide form. This is similar to the way we list potassium oxide instead of just potassium on our labels in the...

    Plant Available Silicon, Soluble Silicon In Fertilizer Sources, Aafpco Approved Method

    I sure would not say NO ONE is testing for silicon in the cannabis scene. wink wink muwhahahahahahaha the 5 day sodium carbonate-ammonium nitrate extraction is an analysis method, not a production method. it is the AAPFCO approved testing method for plant available(soluble) silicon content in...

    (Fatman's) DIY nutrient mixing guide

    simply dilute 0.5 grams of 100% anhydrous citric acid crystals into one liter final volume of distilled water. Concentration(stock) × Volume(stock) = Concentration(dilute) × Volume(dilute) so 100 times Unknown equals 0.05 x 1000 1000 x 0.05= 50 50/100= 0.5

    Masterblend 3 Part Feeding Chart?

    Just a note to point out that when you mix the masterblend, calcinit and epsom together as a dry mix, the final N-P2O5-K2O grade is not 20-18-38. It is more like 7.8% nitrogen, 7.2% P2O5 and 15.2% K2O. 1.6 units of 4-18-38 = 6.4 - 28.8 - 60.8 1.6 units of 15.5-0-0= 24.8 - 0 - 0 0.8...

    Best Silicic Acid: Aptus Fasilitor, Mills Vitalize, Osa 28 & Power Si

    Here is a study that came to the conclusion that a peg400 stabilized silicic acid formulation Silamol was " just as efficient when used as a soil amendment at an equal dose of 1.7 mM Si" as potassium silicate Kasil 6 (AgSil21). So i still say show me the research that proves the stabilized...

    Best Silicic Acid: Aptus Fasilitor, Mills Vitalize, Osa 28 & Power Si

    show me the scientific study that proves the choline chloride or peg400 stabilized silicic acid products are more effective than regular potassium silicate dilutions at providing plant available silicon. I've not seen one yet. Lots of marketing mumbo jumbo, no proof...

    No such thing as a open rated single jacketed ceramic metal halide. See the "E" on the end of the lamp model, that means it is only intended to be operated in an Enclosed fixture.

    Mammoth P???

    Thanks for clarifying. That does not indicate that the product contains synthetic plant hormones and Polyacrylamide. If it did they would have listed the concentration. For example as seen here.

    Mammoth P???

    @ Jahworks care to site your source for the information you presented? I checked your first claim, that Mammoth P is not OMRI listed, and you are incorrect. As it is OMRI listed. see link here. So i find anything else you stated to be dubious.

    Yes, I am serious. As to the second question, "how do you think all the amendments have become available from basic NPK?" I do not understand what you are asking me here again. Learn to phrase your questions so that I can understand what you are going on about, or expect to not get answered...
