I'm afraid I have no good method for large quantities- I've ususlly just hand-picked from small amounts of castings- though if they're left to dry a bit first it is easier to see the cocoons. The best thing would probably be to keep the castings warm, on the dry-ish side, and put some moist food nearby to attract the babies as they hatch.
Of course one of the reasons castings are so valued in the garden and in agriculture generally is that they have cocoons in them and thus help to continue enriching soil after the cocoons hatch.
"Ed, I have 4 bins in my garage where daytime temps were up to the 100s for at least 14 days. I added more crbons to the bin and froze the fresh food before feeding them, the bin temp stayed to about 80 but never over 85 degrees. I covered my bin w..."
This is a post that you made...what do you mean by crbons...is that carbons? And what specifically would that be? I live in SE Iowa and the heat is on! Thank you for your help. Cathy
No I haven't used a thermometer to check the temp...but sometimes I can feel the heat. I have started putting the food in just one corner (vs spreading it around) and I put a frozen bottle of water in the top bin. I do freeze my food. Do u put the frozen food in? Or do u thaw it out? I have been thawing out my food before I put it in the bin. I am still confused about the word "carbon" Is that a specific type of food? Cathy
Wow, I didn't even know your question was on my page. Sorry for the late reply.
To harvest the big FTs, people use the 3 timed garden forks and pull the tines across the bottom. Since I have such small bins, I put them up on my work table and use my fingers to pull stuff out. With the wires 1" apart, it was harder to get the finished VC out. You definitely DON'T want a grate. It would be a nightmare when you wanted to harvest. If you have a grate, you might need to change it out the first time you decide to harvest.
I don't think I'd do anything different other than what I mentioned in the blog post. (Make sure the newspaper covering the wires goes up the sides a little before adding everything.) I'm really happy with them. I just wish my worms would reproduce more quickly! I'd love to add more stuff.
