Nano breathe is good juice, to clear any confusion, its a nano milled limestone to which we have added some bacteria, with a beneficial mold fungus, and some SiO4, biostim BAS not synth PAS. This increases plant available CO2, the microbes help to fix atmospheric N and provide plant defense boost, the SiO4 balances the internal plant sap pH for better hydraulic capacity, eg it pulls more solution, so more nutes and because the balance is right in the vascular systems of our plants, more of our inputs, NPK etc, gets used properly, with less requirement overall, and it counters abiotic, biotic stress vectors, which have a dramatic impact on yield. Plants in high heat etc, will suffer worse in many cases than plants getting bitten come time to harvest, if we can keep the internal pH right, we get higher BRIX, less visible plants to biting insects. Its a proper high grade pro floraculture product, which we morphed from high end glasshouse flower production in to high end everyday easy peasy. :-)
If we can keep the internal pH right, we can worry less about the media pH and feel better that our plants are keeping more of the nutrient value
