thanks Stucco,
yes, love asparagus. one of the large GB's will have asparagus and yukon gold potatoes on an irrigation system in coir and perlite. i don't know how well it will do, i believe with irrigation it will do very well. when i tried some with a bell siphon, it did nothing. commercially roses are grown hydroponically in coir and perlite with timed irrigation. they are watered 15 times per day. of course the best fertilizer you can give a rose is water.
at my place in NM asparagus did fantastic in the desert. it does not like wet feet. so far the asparagus in the pots has been watered once a day. the nitrates in the Biopond is somewhere around 40ppm. way too low for asparagus. i am counting on the vermiponics to pull it off.
