I'm interested in culturing Grindal Worms again but this time am determined not to have an inevitable crash about a month in...my question is what do I do when I'm gone for a few days or so? I'll be going on a short trip or two in December and don't want to come home to dead worms...i can have someone feed them for me but does anyone have any other tips on how to maybe automate the system in some way? Last time I left for a few days it was a disaster....thanks guys!
