Neophyte needs help
For a couple of years I've been tending a three-tray "Worm Farm" setup. I get a kick out of all my little red wiggly pals though they never seem to behave as I expect them too. My chief puzzlement and disappointment is that over the two or so years I've been feedin' em, I've harvested, what I consider, only a paltry amount of castings, probably no more than ten pounds.
My "operation" has some significant limitations which may fully explain why I remain a small-timer. If so, some of you experienced guys and gals can tell me so. Hopefully though, you may have a hint or two for me that will allow me to boost my pals output.
From this forum I learned that corrugated box material makes excellent bedding 'cause the worms like the glue. So that's what I'm now using exclusively. Also, I read a comment here to the effect that "you can't have too much bedding." So I've been adding relatively copious amounts of corrugated. Aside from the small size of my "Worm Farm" set-up, I think the most serious limitation is that I have no temperature-controlled space in which to keep the "farm." Consequently, it is subject to significant swings in temperature as the seasons pass. Though I do protect it from sub-freezing winter cold, during the summer the carport closet it's in approaches 100 degrees at times. I process most of the food to near-puree size pieces and very recently I've begun giving them coffee grounds.
My understanding is that if I do this right, I can expect the worms to very gradually migrate from a lower to a higher tray by withdrawing food from the lower tray. I've never really been able to achieve this. My few "harvests" have been done by the tedious process of manually transferring the population of one tray to another, worm-by-worm, leaving typically, a rather soggy product which I then air dry for a day or two before using.
Finally, I have to add, that when I dig this stuff in around a flower in the garden the results are indeed impressive. I think the plants like it as well as the worms like coffee. Thanks in advance for any help.
