Human demand of oxygen depends very much on activity level. But it should be possible to control the amount of oxygen produced by the hydroponics by varying the intensity and daily duration of ilumination. Without light, no oxygen production is possible. But plants consume carbon dioxide ehaled by the humans to generate oxygen. Thus the amount of oxygen depends on the amount of carbon dioxide available. | |

| Mar 7, 2018 at 16:10 | comment | added | geoffc | Right, but they had too much oxygen, and limited nitrogen. So they would have to reduce the oxygen content. (And I guess their plan had been to vent it, and easier to vent air (not seperated O2) which would take Nitrogen with it). | |
| Mar 7, 2018 at 16:07 | comment | added | PlasmaHH | That does not seem to make much sense, plants do not produce oxygen out of nothing, but from the water and then consume the co2 out of the air. No co2, no O2. | |
