The jar, a standard 4" net pot filled with perlite topped with a quarter inch of coir sprinkled with activated charcoal and you have a nifty little hydroponic garden, Oh, I forgot to mention a short strip of felt to act as a wick. Add the seed and fill the jar with water and a dilute solution of water and any good soluble fertilizer and you are good to go.
Forcing bulbs is also a way to add a little color and fragrance to the house during winter. Several types of bulbs can easily be forced into bloom with again no maintenance.
I have always had a passion for photographing wildlife. It has the same thrill as hunting, but without the blood, gore and recrimination of killing a living creature. The photo above is of female Downy Woodpecker.
When the weather is really lousy there is always table-top photography to pass the time. The above photo I have named R2D2 meets H2O.
Oh, the joy of being retired!
