First I want to thank all of you for reading my blog and being interested in what I have done on hydroponics salad green table project. I kept maybe 10 plants (mostly because they flowered already) and the left were thrown out. There is not any follow up statistical data analysis for this second phase of hydroponics project, since almost all of the plants got hit by ghosting problem and severe tip burn. Professor Michaels suspect that some kind of air-borne disease might be the cause for ghosting problem, since salad greens other than lettuce (which was not part of my project) had same problem. On the additional note, some seeds from the first phase (F1) were planted out in the field during summer 2015. It looked like they were doing great, however, after the mid-harvesting season, all of them collapsed and did not produce any seeds. So, I personally think that if I were to work on this project again, I need to get seeds which are more resistance to the soil and climate in Minnesota.
