I’ve gone into how I care for my Hoya macgillivrayi that live in my grow tents quite extensively in the past.  Here is how I care for my Mac that just sits on the windowsill.  I water with diluted fertilizer once a week; give it a shower twice a year, and that is it. My plant is around eight years old; I keep it at 4 feet high, and it lives in a 10 inch pot.
