Toronto has many overcast days in autumn and winter. My outdoor succulents do not seem to get enough light.
I measured the lighting in my growing area where the plants are under three full spectrum plant lights. Each light bulb only uses 8 watts and emits 800 lumens.
In an overcast day, my plants can get 200-500 lumens under plant lights for 10 hours. When the sun shines, the light lumens can be 1000-2000 lumens.
In comparison, the outdoor light is only 100-200 lumens when there is no sun.
In order to use the plant lights efficiently, I had to pot some in a group and repot them in the spring. Of course, I will only water sparsely during the winter.
I may try to buy some stronger light bulbs.
