Our experiment has entered it’s sixth week and will be shortly heading into the middle of the summer when they will be exposed to the most sun.
The test plants are looking fairly healthy but have lost some of the red colouration from their leaves in comparison to our control plant which is in a sunnier area. The maximum trap width of all of the test plants has not changed measurably so far.
Specimen A: Low light, distilled water
Specimen A, which is being watered with distilled water and grown in a low light environment is looking okay, but it’s leaf-base is weakening, causing the trap with the longest leaf-base (bottom right in above photo) to droop towards the ground. The initial angle was approximately 30 deg. from vertical, however it is now closer to 30 deg. from horizontal. This plant has grown an extra trap and a further three stems are growing. Unfortunately, one of the new stems has begun to turn black. A fly was fed manually to this plant one week ago, the trap is yet to re-open.
Specimen B: Low light, tap water
Speciment B, which is being watered with tap water was manually fed a fly one week ago, it’s trap is beginning to re-open. One of it’s traps was triggered, but did not catch a fly, this trap re-opened within 48 h. This plant still has three traps, but another trap is in the process of opening and another stem will probably be forming a trap soon.
Specimen C: Control Plant, medium light, distilled water
Our control plant speciment C, is looking nice and healthy and has caught a fly naturally and been fed one by hand, both times the traps re-opened within five days. The red colouration in the leaves is not as intense as they were at the beginning of the experiment, but not hugely so. The total numbers of traps is still six, however their leaf-bases are noticeably longer than when purchased.
Conclusion
This is early days yet, so there’s not much that can be concluded from the results so far. However initial results are showing are indicating that the control plant (specimen C) is coping with it’s new environment better than the two test plants in dim light (specimens A and B). Specimen B which has been watered with tap water appears to be slightly healthier than specimen A which has been watered with distilled water.
Information will be posted here eventually with information about the amount and composition of dissolved solids in the tap and distilled water used for this experiment and the approximate daily average light intensity that the plants are exposed to.
