How I made my indoor compost bin - in 6 easy steps (with pictures)

Fig 1 - Start with 3 tubs which fit-in (top one has a lid)

Fig 2 - Drill 1/4" holes at 2" distance on top two bins
(both sides) and bottom of top two bins as well

Fig 3 - Tear up newspaper and make the first layer. Make
wet  by sprinkling some water. Adding worms (red) is optional,
but these lovely creatures make things happen faster.

Fig 4 - Add shredded kitchen waste. Avoid meat,
dairy or pungent vegetables (garlic, onion etc).

Fig 5  - Add a layer of leaves/hay and some earth on top.
Green to brown ratio should be 1:3.
Give it a weekly mix. 

Fig 6 - Drill a 16mm hole and fit a tap for draining
nutrient rich compost tea to use in plants. Keep in a dark,
dry and cool space like under the kitchen sink.
