Hi All,
I am trying to understand light level requirements for Paphs. My books suggest that a good and easy test is whether your hand casts a shadow on the leaves - the suggestion is that there should be no distinct shadow. (I think that the assumption here is that we are talking about sunlight rather than artificial lighting.)
Reading this forum I understand that different groups of Paphs have different light requirements. However I only have one fairly small greenhouse, so the light levels are going to be fairly similar everywhere.
Here are two pictures taken today, showing the shadow cast by my camera outside the greenhouse and inside the greenhouse on a sunny afternoon in England (yep, really!). The shadow inside the greenhouse is faintly visible under the 50% shade cloth I currently have in place.
What is your advice - is this shadow test a useful one? (It is certainly easy to do.) If you were to do this in your growing conditions would there be more or less of a shadow cast?
I will be grateful for any help.
Regards,
Ian
