Summary: Alfalfa recently cut, did spectral and veg height

Arrived 14:05. Sunny, breezy, alfalfa recently cut.

Did soil respiration, collar 3 (third set) not a good measurement: might want to play with set point measuring for ~100 seconds each time.

Measured veg height (cm): 10, 4, 8, 5, 12, 19, 11, 14, 9, 22, 22, 23, 17, 20, 17, 16, 16, 14, 11, 12

Took spectral: 3 sets of 2 down, 1 up.

LI7500 readings
CO2 389
H2O 558
T 21.15
P 101.37
ss 82.4 -> 86.6 after cleaning

Old Canon camera seems to be dead - removed.

Did not collect FD chamber data.

Veg Height (cm): Tape measure from ground to top of plant
10, 4, 8, 5, 12, 19, 11, 14, 9, 22, 22, 23, 17, 20, 17, 16, 16, 14, 11, 12, avg = 14.1, stdev = 5.52
