Project: GreenHab - Plant maintenance, pH meter Calibration

Personnel:
Tulika Raj

The pH meter was calibrated using a 7.00 pH buffer. The GreenHab
temperature was 82 degrees Fahrenheit.

Technical/Equipment Issues:

None

Discussion / Questions :
The water hyacinth tank (AT2) is full. Does it need transplanting?
However, AT1 is very frothy in appearance, as well as AT2 is starting
to get a little frothy. As mentioned in the earlier report, Crew 68
tried to transplant the water hyacinth from AT2 to AT1, and the plants
do not seem to survive. Thus, they were placed back into AT2.

Which pH meter needs to be used for checking the pH of the GreenHab
aquatic tanks with the plants? I think there are two pH meters here.
One of them is older than the other.
The buffer that was opened for pH calibration needs to be disposed.
Where does this go?
