It is not easy to find information of complete VFT lifecycle in cultivation. There are fragmented postings of the the plant in various phases. I am starting to grow from seeds. This is a good place to document the development. Also to serve as a reference growing the plant till mature plants are obtained.
Phase 1: Germination
================
Temperature: 29 Celsius, day-night difference about 3 Celsius
Light: Direct sunlight 3.30-5.30pm, indirect sunlight the other time
Water: Rain
Relative humidity: 60-90%
Soil: Dried long fibered sphagnum moss (LFS)
No cold stratification. Seeds are put within 5mm from top of LFS.
The setup is shown here.
Germination stages:
Day 16
Day 23
Day 30
Seeds germinated: 46% (11 out of 24)
2 seeds wilted before putting up trap leaves. No obvious reason, likely to be weaker plants.
I believe all viable seeds have germinated. Some statistical analysis here,
Mean: 14.55 days
Standard deviation: 2.73 days
With the information, graphs based on normal distribution can be plotted.
Figure 1: Germination on a particular day after sowing.
Example interpretation:
4% of viable seeds germinate on day 10.
15% of viable seeds germinate on day 14.
Figure 2: Cumulative germination on a particular day after sowing.
Example interpretation:
By day 17, 80% of viable seeds should have germinated.
By day 20, 98% of viable seeds should have germinated.
Viable seed estimation: If 20 seeds are sown, and 10 seeds germinated by day 17, you may predict total viable seeds 10 / 80% = 13 seeds. The remaining seeds are likely not viable.
The graphs are constructed based on small sample I have. Regardless, it should give a rough idea on germination rate and duration.
Phase 2: Growing
=============
As the seedlings start to put out trap leaves, they are now in growing phase.
Conditions remain the same as germination, except the direct sunlight duration has increased to 3 hours, ie 2-5pm.
Will update as it goes...
