the recent rains have made my buds drop! when I move the pots out of the rain they get little sun. was thinking of using a big pvc golf umbrella on a patio table. if blown over, it would have to take the iron table,too. why can't Sun get thru clear plastic that doesn't block UVB/A/C? I only have about 8 pots that would fit under an umbrella just fine on those days when rain is predicted. If no rain comes,I thought at least it wouldn't miss a day off sun.
