I figured some of you might be wondering how my Compost Sak vermicomposting system is doing these days, so I recently assessed the situation. As you may recall, I never really stocked it with a lot of worms – I basically just added some material that happened to contain some worms and cocoons when I first set it up (plus one small addition of worms on another occasion). This combined with with fact that I added a lot of waste material during warmer periods (causing the system to heat up quite a bit) left me unsure as to what I could expect to see in the way of a worm population.
Interestingly enough, the system is absolutely loaded with Red Worms now – and they are distributed throughout (rather than just down in the bottom). I think the onset of cooler weather and a bit more “neglect” has definitely helped a lot!
All in all, I am really impressed with how well the Compost Sak works as a vermicomposting system, and a composting system in general. Like I said, I added a LOT of wastes to it while it’s been up and running (and didn’t really do much to “optimize” these materials for faster break-down), yet most of it seems to have been converted into rich, dark compost already.
I don’t think Compost Saks would necessarily work well in every situation though – at least not for vermicomposting. In locations with very hot, dry summers, you may encounter issues with overheating and/or drying – but then again, if it’s kept in a well-shaded location and watered regularly, perhaps the excellent “breathability” would keep it cooler than various other types of commonly-used outdoor composting systems.
Bottom-line, it’s safe to say that I’m officially a fan of this simple (yet effective) composting container, and will certainly continue to use them! By the way, my other Compost Sak has worked very well as a tomato-growing bed – but I will more than likely switch over to “Smart Pots” next year since they are designed specifically for growing plants.
