Mine is indeed 'greener' then most pictures i saw of it on Google, first i thought the flower would change color in a few days, but it didn't (yet) It has won of the brightest spots in my greenhouse, with it's nose almost up to the glass, and close to the heating, because in wintertime the sun doesn't shine very often here in the Netherlands.
In summer the temperature go up to a 30-33C, and drop at night to 22-24C, in wintertime the temps lie closer together, 22-25C at day, 18-20C at night.
All my orchids get fertilizer with every watering with Akerne's rainmix! And they seem to like it a lot!

I copied the explanation for the fertilizer from Akerne's website:
(NPK 13+3+15+11CaO+3MgO)
As orchids can flower at any time of the year, it is not always clear when one should use a fertiliser for growing or one for flowering.
This problem can be solved by using a well balanced fertiliser year round.
Following an article published in the american journal Orchids (June 2003) regarding the development of a new well balanced orchid fertilizer, the so-called 'MSU fertilizer' of the Michigan State University, we have together with a few selected orchid amateurs redone the tests over a two year period and this with results beyond expectation.
This well balanced orchid fertilizer which we offer you today is the result of more than ten years of research.
This fertiliser in powder form has been especially developped for use with rainwater, RO water or soft city water.
Akerne’s RAIN MIX ® is based on the following principles:
- All the nitric nitrogen in this fertilizer is directly absorbed by the plant. This fertilizer does not contain any Urea ( a cheap nitrogen source) that requires high temperatures in order to be absorbed by the plant, resulting in a premature breakdown of the substrate due to micro-organisms.
- This fertilizer also contains Calcium and Magnesium, necessary for the cell production, it can feed both roots and leaves.
- A low phosphorus 'P' content. The study has shown that a high phosphorus content is not necessary for a better flower production in orchids.
- All necessary trace elements are present: Fe, Mn, Zn, Cu, B and Mo.
The price for this new fertilizer in powderform, completely soluble in water, is cheaper than our previous liquid orchid fertilizer (taken into account the NPK concentration and the volume/weight) and far cheaper than the low concentration liquid 'Grow' and 'Bloom' orchid fertilizers.
With the recommended dosage of ½ gram per litre at every watering it is not necessary to water with pure water in between.
