|Growing Standing Stone|
The Growing Standing Stone is a block added by Roots. It will make all crops inside its 9 block radius grow faster when powered by Redstone. Each 50 ticks (or 2.5 seconds), there is a 5% chance of the "age" of the crop increasing by one (most crops have an age of 7 when fully grown).
The Growing Standing Stone is created in a Ritual. It requires an Attuned Standing Stone, Glowstone Dust and a Runestone Symbol to be placed on the Casting Altar and one Verdant Sprig, one Infernal Bulb, one Wheat and one Birch Bark to be burned in the Incense Brazier. The Ritual requires Attuned Standing Stones to be placed around it.
