Red production in Drosera with artifical light

[Swerfer]

Hi

 

I am planning to make a small terrarium with artificial lighting with the sole purpose to colour up Drosera intermedia tropicals, in a healthy way. Thus I am studying the various light spectra and purposes of different wavelength colours suitable for plant growth. It is a difficult subject and every grow light manufactures states their product are the best. Most of them use a combination of red and blue light, ratio 7:1. Does anyone have experience with these LED grow lights in relation with Drosera, and particularly Drosera intermedia tropical forms?

 

This is an example of how I want to achieve my red colour, a sort of maroon red

What produces the redness in Drosera? I think it is mainly Antocyanin. So which colour spectra or colour LED combination makes Drosera produce Antocyanin?

 

Some LED manufacturers state that the use of green LED in combination with Red and Blue produces the largest amount of Antocyanin. But scientific articles state that plants in particular cannot use the green wavelength tot heir benefit and thus stay green?

 

I am a little dazzled right now, so want some advice of LED users.

 

Any help is welcome,
