Get hold of few Asparagus seeds in October and I am trying out this veg see whether its do able in Aquaponics.
Asparagus update 29th Nov : Here
It the Mary Washington variety, this type recommended and can be grown here in sunny Equatorial region.
I use a smaller grow tray within my black growbed, to ensure those seeds did not get suck down into the deeper part.
I only sow few seeds about 20 and see how it goes, don't know what to expect. It will takes some time for Asparagus to germinate and may takes as long as three years for it to produce.
Due to long period, this plant may not be suitable for Aquaponics.
