Incredibly elaborated & very instructive discussion on a subject on which I clearly need constant enlightment. Al, thank you very much for sharing your knowledge & experience. Your way to approach the growing experience is really inspiring. I already did my very first 5.1.1 mix, a great experience. It felt like I was doing the right thing for my trees. The group overall is really great, people from so many different places coming together by their passion for plants:) I'm planning the 2017 spring bare-root up/repoting of all my plumerias and I plan having them all going into the GMX medium. Could you please help mewith some questions? 1) Turface = is unheard of here in Belgium/Brussels area. Can I replace turface with pumice at equal proportions? What do you think about mixing Pumice 4 + Bark 3 + Granite 2? 2) Crushed granite = also hard to find with the size required by the GMX. If I replace the granite with perlite the ingredient distribution in the GMX should also change? What do you think about mixing Pumice 4 + Bark 3 + Perlite 4? 3) Is the volcanic lava (3 mm size) a good replacement for the crushed granite in equal proportions? Thank you very much for your time. Regards, Michael

I am replying just to bump this down. I don't think that advertisements belong here.

I know what NOT to eat and that is SUGAR. White over processed artery clogging cancer feeding SUGAR. BE it cane or organic - it is going to kill you. Use organic leaf stevia, xylitol (keep away from pets) or a little bit of organic raw LOCAL honey ONLY PLEASE!! White processed flour/rice/breads, etc turn into unused glucose in your blood. Sticks to arteries. Causes heart issues. Inflammation. Diabetes. Infections if there is alot of MOLDS and FUNGUS in the grains used - which there IS!! Most of the processed your body cannot even use. Go GLUTEN - wheat/barley/oats/rye FREE! Go quiona, tapioca, kaniwa, etc. Your body will love you for it. Ease up on HIGH sugary fruits. Berries are good. EAT PLAIN ORGANIC Kefir or Yogurt and add berries/stevia. It is good. (the stuff on shelves has ADDED junk to keep their profits high at your expense. Trust me. They don't care about you - why should they? THEY WANT YOUR $$$) Eat more fermented (raw/organic) nut butters, etc. Good for your gut lining. Supplement with iodoral iodine, selenium, magnesium, vit c, vit d3, vit b complex, to name a couple. be sure you are taking the right type and at the right time. Plant oils. Very important. Free range Beef, Bison, Chicken, Turkey, eggs if you go that route. Pastas made by Andean Dream are really good. So are the organic brown rice - don't over do the rice, tho. Udis rolls. Pizza crusts by Chebe. Made fresh by YOU! BUY YOUR Tomato products in GLASS only due to the preservatives. BPA is high in the canned products. Frozen organic berries and veggies are fine. Just none from China where COAL is the main source of energy and it poisons the air/water/ground. Always check the country of origin. Be aware that Chocolate is being harvested by mere children that are NOT being paid fair wages. Think NESTLE! MARS candy. THEY DO NOT CARE about children in other countries as long as they keep their profits high. Yet their target demographic is children here in the USA. Buy fair Trade coffee, teas, cocoa please. So, good health to you all.
