I spent many years keeping salt water reef tanks. What I liked the most was there was never "one right way" or "one right
answer"...took a lot of trial and error.
Going organic for my lawn...composting and making compost tea seem to be exactly the same. So many good ideas and very few are the same.
Alison -The idea for the tumbler idea came from my back problems. I didn't want to introduce a chore that might cause me to bend over and use my back. I also like the very clean look of the drum..also don't have a good spot for a three bin compost pile although I'm sure that would work better. If the drum works I may setup two of them so there at different stages.
Also, I don't have a veg garden. I do have herbs and lots of plants in need of good soil and my
lawn soil has been ruined by using chemical fertilizers...it's dead just a couple inches under the nice green grass so I do need to get compost on that. Will likly do a top dressing and apply tea.
Chuck - I agree. I've seen a 2" pipe in the center with air holes lettnig air in from the bottom as well. That plan also called for drilling 3/8 in holes all around the drum.
Brenda - Glad to see yours is working. Mine will be just over 55 gal (220L) and will be mounted on a strong stand so I can spin it end over end to mix things up. I don't plan to put any holes in the top lid so the rain water
should only get in through all the small hols in the sides. I can water it myself (rain drum) as needed.
