That is IV as in ‘intravenous’ not “4” by the way!
I seem to be on a roll with getting posts published today, so I figured why not continue to ‘go with the flow’.
As you may recall me mentioning, I am now basically an open vermicomposting system convert. I love the fact that the air flow in these bins is so much better and they don’t end up with water pooling in the bottom – so it is easier to produce good quality vermicompost.
While I still love my Vermicomposting Trays, I’m starting prefer using shallow (but still deeper than the trays) 55 liter Rubbermaid tubs (without a lid, of course). I find these hold moisture a bit better, plus I can fit two of them per shelf on my vermi shelving unit, while only a single tray will fit on each shelf.
Since these open systems DO gradually dry out over time, I have to periodically water them to ensure that the worms stay nice and moist down below, and that the decomposition process continues to move along.
I’m not a big fan of just dumping water on them however, since it generally just runs straight to the bottom without really soaking the composting mass. Sure, it does get wicked up and spread around over time, but still – I’d rather introduce the water at a rate that will allow for it be be soaked up right away. My preferred method when in this frame of mind is the use of a spray bottle, BUT – as anyone who has tried this can attest – it just takes SO long to make any progress.
A little while ago, on a whim I decided to play around with a little contraption that basically releases liquid from a bottle at a fairly slow rate. The cool thing is that – unlike the spray bottle – with this I can set it up then leave it sit (well ok, it is technically hanging from a ceiling pipe in the basement) while I do other things.
You could even add some liquid ‘food’ if you wanted to. For example, today I mixed some baking yeast pellets with water and started dripping it down onto one of my tray systems. I haven’t really tested this out before, but I suspect that the worms will congregate in the region with the yeast water. Even if they don’t directly feed on the yeast (which I suspect they actually would), the increase in microbial activity in this zone would certainly translate into a nice buffet of microbes for the worms to munch on.
I don’t imagine too many people will have a bottle exactly like this (I’ll spare you the details on what it’s original intended use actually was – haha), but I’m sure it wouldn’t be all that hard to rig up something similar, especially if you happen to be the creative type!
Anyway, I will be sure to report back on the results of the yeast feeding!
