Here’s a lovely Platycerium superbum we met at the @thehuntingtonlibrary – 2️⃣ I measured the light in the morning at the point where my hand was: 560 foot-candles.

3️⃣ The more important thing is to get a sense of what the physical surroundings are that produce 560 foot-candles at that moment – essentially asking yourself #WhatMyPlantSees – sun filtered through trees *AND* evenly distributed patches of sky giving indirect light from all around. The inside of your house is more like a cave: opaque ceiling and walls with openings called windows. Measure it when the sun is not shining directly through the window and you’ll see.
