Do you know if the amount of goo produced is proportional to the number of torches, or am I wasting resources by having a tall column of them?
I never really tested it though I am fairly sure that it is directly proportional (2 torches produces 2x as much as 1, 4 produce 2x as much as 2) as mine seemed to have a fairly good output filling up a gold chest in not that long not sure on the exact rate of drop though but I believe each torch has an independent timer for drops not all of them linked.
Or you could try placing the wooden golem on a relay instead of a chest so it would automatically go into the system without needing redstone pulses.
I never really automated mine as I didn't have that much need for it but that would work better but I was unsure whether golems worked with things like relays or not.
