The best endgame base, optimized for money, power, and space. Runs at the lowest possible power of 4250 (factory+mining nodes), making the maximum amount of 2780 stock bills/minute worth of goods, and fitting in just Core and 1 SubPac, leaving 2 SubPacs empty. If you show me a better base, I will take down my post.

Produces (per minute): 18 Buck Capsule A, 18 HC Battery, 120 Amethyst Bottle, 20 Origocrust. With the recommended sub-pac 2 add-on, instead produces 30 amethyst bottles, 18 Buck C, 30 buckflower powder(for depot quests), filling up in 44 hours instead of 11.
Requires full upgrades in Core AIC and one sub-pac, rest can be not upgraded.

Placing guide:

Gather 250 Buckflower, 500 Sandleaf, 400 HC Battery

Go to the Main PAC. orient the depots to the top and the left. Place the 6 pieces starting from top left.

Fill the plants into the seed pickers. Every seed picker that needs to be filled has a item control port showing sandleaf or buckflower respectively. Make the core AIC's outputs 6 ferrium. Fill the thermal banks with HC Battery.

Go to sub-pac that you want to use. Place right, then left. Fill seed pickers and set the AIC output to what is shown on the item control ports.

Switch off excess power thermal banks in main pac.
