Since we first planted our seeds, only one has sprouted. We decided today that something must change. After some further research, we decided to make a few minor changes to our system. We left the one sprouted plant in its cup full of perlite, but we cut a few more holes in the bottom to increase the oxygen that reaches the roots. For the seven other cups, however, we made more major revisions. Since we’re worried about the lack of moisture in the cups, we cut out the bottoms of the Dixie cups and replaced the perlite with rockwool. We’re hoping that the rockwool will absorb more of the nutrient solution and help the newly germinated seeds grow. We’re looking forward to seeing how the plants have progressed when we get back to class on Monday!
