If we start from our conventional tap water we have to take into account the hardness of the water.<\/strong><\/p>\n

Regarding the hardness of the water, we can find water of temporary hardness and permanent hardness<\/strong>, I explain what it is:<\/p>\n

 <\/p>\n

-Temporary water hardness:<\/strong> This is due to calcium bicarbonates. It’s temporary because we can easily remove it by heating the water, chemically reacting to the bicarbonate to convert it into CO2….I know what you’re thinking<\/em><\/p>\n

 <\/p>\n

…<\/em>Is it the same CO2 as the one we use to boost plant growth? Yes, it is the same, although the amount that comes from bicarbonates is minimal to have any effect on plants…. and… is the same with which extractions are made to develop some of the products of CBD?<\/em><\/p>\n

 <\/p>\n

Yes, it is the same, although many kilos of CO2 are used for CO2 extractions.<\/strong> In another post we will tell you how the industry uses CO2 to make marijuana oil<\/a>.<\/strong><\/p>\n

 <\/p>\n

-Permanent water hardness<\/strong>: On the other hand, we have what we call permanent water hardness. It is insoluble matter that cannot be removed by heating, and is mainly due to insoluble sulphates and chlorides. These are the impurities that we can only remove with reverse osmosis filters.<\/p>\n

 <\/p>\n

Hard water generally raises the pH of irrigation water and is very harmful<\/strong> to our substrate and plants, as at pH levels above 6.5 plants<\/strong> begin to lose power to absorb nutrients<\/p>\n

 <\/p>\n

You know:<\/strong> Use osmosis water whenever possible, and control the pH of your irrigation water well..<\/div>\n
