Drosera capensis, a trap with no escape
I wanted to capture this sequence to document the technique of "hunting" of Drosera capensis.
After the fly is stuck to the glue present on numerous tentacles, the leaf rolls up on its prey to make as many digestive glands are in contact with it.
Drosera aliciae to "hunt" of gnats
Perhaps attracted by the sticky tentacles colored pigments with anthocyanins, or perhaps by the growth of LED lights red and blue, an unwary fly is resting on a leaf of Drosera aliciae, remaining entangled.
LEDs to grow plants: low power consumption and high efficiency
Use LED lights for growing plants when sunlight is not available?
This lighting technology can be very advantageous for terrariums: efficient, low energy consumption, little heat and last much.
How do they work?
Each plant pigment absorbs certain colors of light better than others. Chlorophyll absorbs red light very well and the blue, but not the green as the plants use chlorophyll for photosynthesis, the process is more efficient with red and blue light than with the equivalent of green light.
Building a terrarium for carnivorous plants 2 - land and flora
After realizing the 'water recirculation system is the time to fill my mini terrarium with soil and carnivorous plants.
Figure 1 - Layers of soil
Here are the details of the soil layers (see figure 1):
- a - expanded clay (~ 4 cm)
- b - perlite (~ 3 cm)
- c - a mixture of peat and perlite (~ 6 cm)
- d - peat (~ 1 cm)
- and - live sphagnum moss and carnivorous plants (5 different species) + a few pieces of bark
Building a terrarium for carnivorous plants 1 - container and water recirculation system
Glass aquarium 26x16x21 cm
Finally I was able to experiment in building a mini terrarium for carnivorous plants, built at a cost of about 110 euros (all included: housing, plumbing, lighting, soil and plants).
I state that I am a novice in this field that I have documented online and I'm now experiencing some DIY solutions.
As a first step in the container: I bought an aquarium glass of modest size (26x16 cm. - Height 21 cm.) For the modest sum of 20 euros at a dealer of aquariums, with a bit of time and good will could realize a cutting of the glass plates and sealing them appropriately with silicone.
