Wind Row System. Place food on the right hand side of the row and keep it moist. Scrape vermicast off the opposite side because the worms will gravitate towards the direction that you feed them on. Therefore, you are able to remove the vermicast from the left and it won’t contain any of the worms. Pond System. Start at the bottom-15 centimeter (5. 9 in) compost. Keep adding 15 centimeter (5. 9 in) compost at a time till pond is full. Remove whole pond to wash. Wind Rows Undercover. Food is placed on front and kept moist. Vermicast is scraped off the opposite side. Feed from the front, worms keep moving forward so what you remove from the back won’t contain any of the worms. This is usually done in sheds and on a smaller scale.
