The Lamp of Growth is a device for speeding crop growth in the vicinity, by supplying extra "growth ticks". Key points:
- It requires Herba essentia, which must be provided by a pipe. The ammount of essentia used depends on the number of eligible plants within range.
- It affects all growable plants (crops, saplings, sugar cane, cactus, mana beans) in an octogonal area 12 blocks across as shown.
- The effect can pass through solid blocks, and the effects of multiple lamps stack.
