Re: Collecting Grindal Worms
Rubbermaid has a new flat container with a two-gallon capacity ( 8-quart
servn-saver ) about 9 1/2-inches by 14-inches by 5-inches deep which I
have adopted as my standard worm container. One neat thing is that it
is stackable and tightly sealed. I open them roughly once every two
weeks for air exchange unless I have opened them for collection or
feeding on a more frequent basis.
I have found new cultures should be fed small quantities of your food of
choice weekly with as little disturbance as possible. Once established,
feed as soon as the last feeding has been consumed (more to keep the
worms in the feeding area for collecting than anything).
Temperature and moisture seem to be critical for grindals as well as
white worms. Grindals 65 to 70-Degrees seems best and whites 55 to
60-degrees seems best.
