Environmental Variable (Fertilizer Variance) Looking at number of blooming flowers (BF), height (H), and petiolar trichomes (PT):
Observations:
PT: High fertilizer=more PT (generally)
BF: High/Low fertilizer alone doesn’t seem to have any bearing on the number of blooming flowers
H: High fertilizer=taller plants
Conclusions:
The higher fertilizer increases the height of all seed genotypes (both petite and standard). It does not, however, have any affect on the number of blooming flowers, though it does seem to increase the number of Petiolar Trichomes in both genotypes. Petite seeds in general have fewer or no Petiolar Trichomes, except in Oswald’s case. (As a side note, high lights, except for Bruce, seem to have more blooming flowers than low lights)

With Genetic Variable (standard seed vs. petite seed), Looking for height, petiolar trichomes, and number of blooming flowers:
Observations:
Seed: no bearing on flowers (50/50)
Height: Standard seeds are taller
Petiolar Trichomes: while petite seeds with low light have an equal or greater number of petite seeds than standard seeds with low light, petite seeds with high light seem to have fewer PT than standard seeds with high light.
Conclusions:
The variation of genotypes has no bearing on the number of blooming flowers, though high lights in the case also seem to have more blooming flowers. The height was affected by the genotype—standard seeds are considerably taller than petite seeds. While petite seeds with low light have an equal or greater number of Petiolar Trichomes than standard seeds with low light, petite seeds with high light seem to have fewer PT than standard seeds with high light.

What characteristics do genetics affect? Height, possibly Petiolar Trichomes
What characteristics do environment affect? Height, number of blooming flowers
Based on our data, our story is that genetics and environment affect all aspects of growth.
