personally if Ive been mowing the lawns I may do but not the cultures
I also use the same product with white worms. Seems to be less messy and the worms stick to the glass easily.
I think that the secret may be to put a little less feed in for them so it dosnt get a chance to go off.
With White worms, they create a ball of worms on the edge of the lunchon and you can remove them with a teaspoon with out removing any of the peat making feeding as easy as opening a beer
