I love how easy it looks to harvest with this clay method. I do the charcoal method to raise springtails and harvesting is a bit of a hassle for sure. I generally just take some charcoal out of the culture and place it in my froglet terrariums and replace it every day or so with fresh charcoal from the culture. This looks much easier - just like harvesting fruit flies. I plan on researching this method more. Thanks for sharing!
They're made using a clay media as a substrate. I sell the clay shown in the video on my website: frogandfrond.com/product/calcium-bearing-clay-springtail-media/ You can see a bit more detail on making the cultures in this video: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-6BGAf7oxCQk.html Thanks!
