Barley, wheat, and brussel sprouts. The goldies should overwinter in the tank, and the movement should prevent solid freezing of anything. I'm also thinking about wrapping the white tubes in black wrap for extra heat. Barley is supposed to be a great "nitrate filter," and it grows better/only in colder climates.
As for the worms, I plan on tricking them into real composter bins with food after harvesting all the summer plants. Some will stay, most will go for the bread in the composter. They love bread like Tyrone Biggums likes his crack.
I will do the same for the bio-filter bucket, with the exception that the entire bucket will be replaced with a new gravel bucket (worm-less until next grow season) and left to run to suck up and store worm food for next year. Then I will add the worms and plants back same as this year, and it will have gone full circle.
You guys all need manure worm compost bins IMHO. These things are great for everything from "all" your house wastes, down to just a small coffee grounds and bread only "little" system. These worms, when happy, eat their weight in food everyday and make 100% water soluble 1-0-0 NPK fertilizer that is impossible to burn your plants with. Worm poop is the perfect nitrogen fertilizer, even surpassing guano for the simple fact of it's non-burning traits.
I'm doing a 7-11 Big Gulp worm bin for indoors this year. I won't even make it to the ceiling stacking these cups upon themselves for a worm bin, so that is pretty space efficient. Basically cups with holes in the bottom, filled with a little bedding (damp not wet shredded paper), and then add food on top placing more bedding on top of that. Close it off from light since they hate it, and make sure any air holes are small enough for gnats/flies/insects to not make it inside. They don't stink when you do it right, and makes your garbage work for you.
I composted an entire years paperwork that filled a 55 gallon garbage can into a large coffee can of pure compost. My parents were amazed. If I had used that same paperwork (for bedding only for my worms) and done vermicomposting on the same pile of paperwork, I would have been able to make 10 times as much compost. This is because I would have fed them all the other trash as well that was edible. So, we threw away all that fertilizer in my mind, and the trash stunk up the garage until trash day. Seems win-win-win to me. I'm using beer boxes as my bedding this year for my worms. I have about 30#'s of beer trash stacked up waiting to be eaten. The cans are getting melted down as soon as I complete my foundry. Now to recycle glass and I will have a curbside trash can the size of a coffee can, lol. Well, I can wish anyways.
I'm not even one of those greenies that has to "watch the planet" with everything they do. I just think it is fun. Al Gore can kiss my grits, a volcano does more damage then You or I ever would to this planet. I just hate looking at trash, and dumps are just that, DUMPS! Must be the Eagle Scout in me
