It's putting on two or three new, large and robust, deep red and olive green leaves each week. The jury is still out on using the sludge as a substrate amendment. I suppose that if there is an improvement from this addition that it's more likely to be from adding fine sandy loam to the substrate than it is from adding sludge to the substrate. I think the method is promising, but there's still a little work needed. In particular its difficult to keep the mixture well-aerated in the aerobic phase of the process and to keep the culture continuously aerated after most of the liquid is decanted and the sludge is held over for the next batch.
Odors are obviously a problem, mostly with the relatively mild odor from the aerobic phase.
Odor from the anaerobic phase is offensive, but that only lasts for a few minutes after the batch is opened and while its being reaerated. I did all that stuff in the garage - not in the house.
