Test finished, hypothesis confirmed. Have put some thermometers into the ground (exactly the same depth, been comparing the equilibrated soil temperatures both in the morning and in the evening), and the results are: Same spot (1 ft from northern end of the tunnel) in those tunnels with the slower plants has about 1.5 deg. lower soil temperature. Inside of one tunnel, the side of the backup plant (closer to the northern end of the tunnel) has about 2 deg. lower soil temperature than the soil around the favorite plant (which is in a more central position of the tunnel). Need to make new plans for next year, for better positioning of the two plants in a tunnel for more similar soil temperatures, which should then allow for better comparison as to which of the two should be the inherently more vigorous plant.
