| Here is another aspect to the lighting questions. I have two south-facing windows, one with more overhang than the other, and consequently less light. The less sheltered window starts getting bright light about 2 p.m. and gets some direct light. Due to double pane windows, it doesn't get hot enough to burn leaves. The other window gets bright light a little later and gets little direct light, only late in the day. When you are measuring foot-candles, how long a time does a cattleya need high light? Are light totals cumulative? It obviously changes during the day. I have a catt which has not bloomed, but it has not been the bright room very long as we recently moved. I'm hoping it will like it's new situation and reward me with a bloom this year. |
