My sampling strategy involved planting seeds of marigold and dandelion species. I did not face major difficulties in implementing my sampling strategy other than acquiring the materials I needed (such as dandelion seeds from the wild). These difficulties were mostly time consuming and did not inhibit my sampling strategy and therefore I do not plan to modify my approach.
A surprising result was when I noticed there was a higher germination rate for marigolds than for dandelions. I think this could be attributed to a source of error in planting the dandelions. The dandelion seeds may not have been placed correctly into the soil and therefore may have had difficulty germinating. Additionally, the dandelion seeds were picked from the wild whereas the marigold seeds were store bought. This difference in quality may have affected the germination rates as well.
Interesting experiment. I was just wondering what your response and predictor variables are? Are the marigolds and dandelions the response variables and the light and/or water the predictor variables? Marigold seeds can also be obtained from home grown gardens, they do not have to be bought which might help ‘even’ things out a little. Some things take a long time to sprout, maybe dandelions are one of them, and how will this affect the light versus sun ratio between the plants?
