Giant spruce TNT farm

Twiti888's giant spruce farm, built block by block by Farmingchunk over an hour. It is 2x2 spruce only, and at 170,000 logs an hour it is the fastest single wood farm in the library. Slime and honey walls with glazed terracotta shove the trees into obsidian blast chambers, TNT dupers fire underneath and ender chests handle the output. It is directional and cannot be rotated, it needs about ten other farms built first to afford the materials, and the comment section is a long list of people who got one block wrong.

• Replace the barrel at 6:34 with two hoppers facing each other, each holding one item. This is the community fix for the piston under the dirt needing a block update, which is what stops most builds after the first tree.
• If the tree will not grow, swap the podzol for dirt. One builder changed nothing else and it worked immediately, though for others it converts back to podzol after bone mealing and has to be swapped again.
• The farm is directional and cannot be rotated. A large share of the failure reports are people who built it facing the wrong way and had to start over.
• For the back sapling not placing, use Carpet's /player use interval 1 rather than an external autoclicker, which runs on real time instead of game ticks.
• Glazed terracotta can only be swapped for other glazed terracotta. Obsidian and furnaces move with pistons but do not stick to slime.
