Glow berries are items you can use in Minecraft that create a small light source underground when attached to a cave vine, or you can tear them off the vine to eat. It restores a bit of your hunger, but it doesn’t do much for your character. Finding these berries can be a bit difficult and you have limited options to find them.
There are two ways to find berries in Minecraft. The first is to rob them of the chest you find inside the mine shaft. The mine shaft has a chance to appear underground or in underwater biomes. They are full of orcs and spiders, so you want to come prepared with a sword, food and decent armor to handle these threats. After defeating enemies, Mineshaft’s chest has a nearly 40% chance of having a bright berry in it. These are pretty good chances compared to a lot of things in Minecraft. There should be few of them.
Alternatively, bright berries should be grown in Lush Cave biomes. However, Lush Caves were not added to Minecraft in the first part of the Caves and Cliff update, 1.17. The vast majority of items that may appear in the cave have been made available. When the lush caves arrive, you will find them inside the lush caves that appear under the Azalea trees. The berries will hang from the cave vineyards.
When you place the bright berries on the bottom of the block, a cave vine appears. You can put bone meal from the cave vine to grow and another glow of berries to appear under it. Although the glow of the berry provides no light when you hold it in your hand, it lights up when it is attached to a cave vine.
You can add cave vines to your home by placing it on the bottom of blocks and looking for creative ways to turn them into lights, not torches. They are not as bright as torches, but they look great and would be ideal for a small greenhouse.
