How do YOU culture Springtails and Isopods?

[BCollie]

Springtails - I have some leftover charcoal but it is VERY small pieces. Can I buy the Natural Lump Hardwood Charcoal, as long as it has no additives such as chemicals or lighter fluid? That way I can easily see how many Springtails I have since the pieces will be bigger(but I can break them up so they're not too big)...or is it better that I use the charcoal that is leftover from making my ABG mix? Or does it even matter?

I plan on going to the store today after school to pick up all the supplies I need.

I'm doing 2 springtail cultures one in charcoal feeding just yeast and one in abg mix feeding rice and yeast. to me the charcoal one seems to be doing much better. isopods take much longer to start producing like springtails do

I think I want to go with charcoal but I'm not sure if I should use my leftover, small size charcoal pieces(from making ABG) or if I should get natural lump hardwood charcoal, or if it even matters...

Left over is perfect.
