Verdant Conduit
The Verdant Conduit is a powerful block found inside some Overgrown Pyramids. When it is activated, it will rapidly spread the Verdant Growth to nearby blocks, while boosting nearby plant growth. Additionally, it will grant players the Verdant Energy effect within a radius, making them immune to the many hazards of the Verdant Growth.
A Verdant Conduit can be crafted out of a Heart of the Forest and eight logs of any type. It's activated analogously to the vanilla Conduit; however, instead of requiring a frame made of Prismarine, it requires a frame built of logs of any type. The frame doesn't have the strict requirements of the vanilla Conduit, however; any log in the 5x5 cube will count. Be careful not to accidentally activate the Verdant Conduit!
Heads up!
You can use any log for crafting the Verdant Conduit; oak logs are used here as an example.
A good strategy for players who have obtained several Hearts of the Forest is to place Verdant Conduits in strategic areas of their bases; this will give them zones of immunity to the deleterious effects of the many harmful plants.
