FTB Power Pots (Forge)
They're Botany pots but with power! ⚡
They have 4 tiers, each tier takes more power but gives more yield per operation.
This mod requires Botany pots & Bookshelf! https://www.curseforge.com/minecraft/mc-mods/botany-pots
Thanks to the original mod author for a lot of the existing functionality.
