Hello, first post..
How do you stop CO2 acidifying the water if using UC style systems?
How do you stop CO2 acidifying the water if using UC style systems?
and you kids that think CO2 tablets are fun… walk into a room at 5000ppm and you might not come out. ;)
1,000,000 ppm of a gas = 100 % concentration of the gas. Therefore, 10,000 ppm of a gas in air is a 1% concentration.
At 1% concentration of carbon dioxide CO2 (10,000 ppm) and under continuous exposure at that level, such as in an auditorium filled with occupants and poor fresh air ventilation, some occupants are likely to feel drowsy.
The concentration of carbon dioxide must be over about 2% (20,000 ppm) before most people are aware of its presence unless the odor of an associated material (auto exhaust or fermenting yeast, for instance) is present at lower concentrations.
Above 2%, carbon dioxide may cause a feeling of heaviness in the chest and/or more frequent and deeper respirations.
If exposure continues at that level for several hours, minimal "acidosis" (an acid condition of the blood) may occur but more frequently is absent.
Breathing rate doubles at 3% (30,000 ppm)CO2 and is four times the normal rate at 5% (50,000 ppm)CO2.
Toxic levels of carbon dioxide: at levels above 5%, concentration CO2 is directly toxic. [At lower levels we may be seeing effects of a reduction in the relative amount of oxygen rather than direct toxicity of CO2.]
fwiw
Am very jealous...
Assuming you use the same strain is there a taste difference between soil and hydro?
