Currently the CO2 level is shifting between 530 ppm to 609 ppm daily, since the new system was setup.  It was set up 3 days ago.  It takes time for the system to stabilize and grow into the environment.  The CO2 levels are way too high for a rodent, yet.  

This system does not have the marine tank connected to it.  Below is the configurations description:

• Two of the three tanks are used.


• 12 hours on and 12 hours off lights alternating tanks.


• Mirrors are placed on some of the walls reflecting the LED light back into the tank at different angles.


• Fans continue to blow air between both tanks.


• The RH is stuck at 99% day and night.


• Dehumidifiers are on 24 hours.


• Temperature is stable at 25 degrees C.


• Oxygen is at 21 to 22 %.


• All other gasses are unchanged.


• More than half of the pots in the tanks do not have leaves growing out of them.  They are still germinating seeds. 


• Ample water is being drawn out of the air to water plants in both tanks. 


• Water is beginning to dry up on the left tank.  (This is the water that poured out of the pots when the system was set up)


• CO2 does not jump up at night any more.  It's a constant average 578 ppm.  Still too high for animals.  Plants have almost grown twice their size from three days ago.  Plants seem to grow very fast in this environment.  

Plans:

• The left tank will have sifted soil placed in it.  


• All of the potted plants in the right tank will be planted into the sifted soil.  Water is being collected from the air and is dumped into the soil.  (This will remove the extra surface area around the pots).


• The marine layer will be connected to the two remaining tanks.


• An attempt will be to lower the RH.  Something as removing puddles of water can help with that.  In other biospheres, the RH settled around 55%.


• Give time for the system to grow into the environment.
