| actually 15 minute is all you need. Since maria is in Michigan , i dont think 30 minute would
do any harm. But be very careful to prevent sun burn. I use direct sun light on the roots.
But it has to be morning sun. Now is summer, morning sun from 7am to 9am should be fine.
sunning is to make use of UV present in sunlight to kill fungus. It encourage the growth of
algae.
I also use direct sunlight to sun my camera lens for 20 minute to prevent the growth of
fungus in the lens. |
