oh, I nearly forgot, I love the duckweed... I pull of about a pound every few days for the chickens and another pound or so to dehydrate in the sun to crumble for flake to feed in the winter when they can't have it fresh.

I also set out kitty litter tubs half full of water in a couple of places in my patio for the mosquitos to lay their eggs in, when they hatch I give it a few days for them to shed a couple of times and then drain the tubs through a large fry net... then I also sun dry these for fish food... why buy freeze dried bloodworms when it is easy to make your own??? After all bloodworms that they sell are mosquito larvae! They seem to prefer my pans over the ponds where the fish may eat them so it saves the ponds and I reduce the population of future mosquitos...
