Currently the CO2 level is shifting between 530 ppm to 609 ppm daily, since the new system was setup. Â It was set up 3 days ago. Â It takes time for the system to stabilize and grow into the environment. Â The CO2 levels are way too high for a rodent, yet. Â
This system does not have the marine tank connected to it. Â 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. Â They are still germinating seeds.Â
- Ample water is being drawn out of the air to water plants in both tanks.Â
- Water is beginning to dry up on the left tank. Â (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. Â It's a constant average 578 ppm. Â Still too high for animals. Â Plants have almost grown twice their size from three days ago. Â Plants seem to grow very fast in this environment. Â
Plans:
- The left tank will have sifted soil placed in it. Â
- All of the potted plants in the right tank will be planted into the sifted soil. Â Water is being collected from the air and is dumped into the soil. Â (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. Â Something as removing puddles of water can help with that. Â In other biospheres, the RH settled around 55%.
- Give time for the system to grow into the environment.
