Left 4 most bulbs are 2 weeks old, the others are 3 weeks old. Top row contains P. Stipticus, bottom row O. Nidiformis. After inoculation, birdseed started growing fastest. However after about 2 weeks, straw catches up and fills the bulb better (as seen in the 1st picture). Also in light production , straw seems to be the brightest.
The left most 8 have been growing for 3 weeks, the others for 2 weeks. The flasks with a dot contain P. Stipticus, the others O. Nidiformis. Similar to the test above, its is clear that bird seed doesn't grow that fast. Only 4 of these actually have started growing the mycelium (the 3 in the bottom left and the one in the middle). The middle left one and the 2nd one in the top row actually are contaminated with the wrong fungus. This could be the result of a non air-tight fit of the cork.
Close up of the contamination: there is a clear green mold visible inside the flask.
This prototype is 2 weeks old. Also in this test, the straw appears to grow faster then the bird seed. The brightness is suprisingly more then the other prototypes. On the backside there is also some small contamination visible, but only on the part with the birdseeds.
Some contamination (green mold) is visible on the seeds.
