Hi Simon,

Of course my remarks about altitude referred only to the tropics. Your altitude in the Netherlands is not applicable, since you are growing in controlled temperature greenhouses.

What matters is temperature. Whilst you referred to 75 to 90% humidity you did not give temperatures.

In the tropics, temperatures lessen with altitude. (As elsewhere.) Here in Grenada at low altitudes we experience temperatures between 75 degrees and 30 degrees. This is too high for A. scherzerianum.

Please let me know the temperatures in your greenhouses.

John.
