Skyblock Greenhouses

Greenhouses are made out of glass and must contain the blocks found in the Biome Recipe to be valid.

To create a specific greenhouse biome, you require permission. These permissions can be found in the Vote & Legendary Crates. 

There is a recipe GUI. Once built, the greenhouse can be used to grow plants with bonemeal, and it may spawn biome-specific mobs. If you include a hopper with water in it, snow will form inside the greenhouse when it rains.

If you put bonemeal in the hopper, biome-specific plants will grow. Some blocks can also transform over time due to “erosion”.


• Craft your own self-contained biome greenhouse on your island.

• Greenhouses can grow plants that cannot normally be grown, like sunflowers.
• Friendly mobs can spawn if your greenhouse is well designed.

• Need slimes? Build a swamp greenhouse!
• Need Villagers? Build a plains greenhouse!
• Need enderman? They will spawn in the End greenhouse, but tp all over the place 😨.

• Blocks change in biomes over time – dirt becomes sand in a desert, dirt becomes clay in a river, for example.
• Greenhouses can run in multiple worlds. You can for instance build all your greenhouses in the End or Nether, if you dont want to spoil the look of your normal island. 
• Easy to use GUI shows greenhouse recipes (e.g. /is greenhouses).

• Greenhouse biomes can ‘bleed’ outside of the greenhouse. Unfortunately, this cannot be mitigated (as far as I know). If you have a good imagination, you can say that the biome of the greenhouse influences the surroundings a bit and it is natural! 

How to Build A Greenhouse:


• Make or buy glass blocks and build a rectangular set of walls with a flat roof.

• Put a hopper in the wall or roof (optional).

• Put a door in the wall so you can get in and out (or sethome if you don’t put a door in).

• Type /is greenhouses and read the rules (recipe) for the greenhouse you want.

• Exit the GUI and place blocks, water, lava, and ice so that you make your desired biome.

• Type /is greenhouses make (biome) to create the biome.

Once made:


◘ Use bonemeal to grow small plants on grass blocks immediately in the greenhouse.

◘ Or place bonemeal in the hopper to have the greenhouse sprinkle bonemeal automatically. Come back later to see what grows!

◘ Place a bucket of water (or more) in the hopper to cause snow to fall in cold biomes. Snow will fall when it rains in the world. Each snowfall empties one bucket of water.

◘ Friendly biome-specific mobs may spawn in your greenhouse.



  • Can I use stained glass? Yes, you can. It’s pretty.
  • Can I fill my greenhouse full of water? Yes. That’s an ocean.
  • Will a squid spawn there? Maybe… okay, yes it will if it’s a big enough ocean.
  • How do I place a door high up in the wall if the wall is all glass? Place it on a hopper.
  • How do I place a door on a hopper? Crouch and then place it.
  • Can I use metal doors? Yes.
  • Can I use a trap door? Yes.
  • Can I grow swamp flowers with this? Yes. Make a swamp biome and use bonemeal.
  • How much bonemeal is used to grow plants? One per successful plant.
  • How much water do I need to put into the hopper to make it snow? One bucket of water (just the water) is used up every time it rains. This only happens in cold biomes.
  • Can I build a Nether greenhouse? Try it and see… (Actually, you may need permission)
  • Can I build greenhouses in the Nether? Yes. You can colonize the nether with them.

What kind of mobs spawn in the biomes?


The following mobs have been setup to spawn in your greenhouses, but ‘natural’ biome mobs might still spawn, for instance, ghasts may spawn in your nether biome, horses in the plains, etc. 

Greenhouses are a very effective spawner replacement and a lot more fun!

Important Greenhouse Tips: 

✦ Polar Bear spawns in water.
✦ Salmon spawns in water.
✦ Wolf spawns on podzol. 
✦ Creeper spawns on red-sand. 
✦ Horse spawns on coarse-dirt.
✦ Bee spawns on oak leaves.
✦ Magma spawns on magma blocks.
✦ Blaze spawns on netherrack and soul sand.
✦ Endermite spawn on Endstone bricks.
✦ Enderman will kill endermite.
✦ Zoglin spawns in lava.
✦ Strider spawns in lava.
✦ Make your Ocean Greenhouse’s water deep enough for Elder Guardians to spawn.
✦ Guardians kill squid, so remember to have a chunk collector for ink sacks or pick it up manually.
✦ Turtle spawns on sand.
✦ Zombie horse spawns on clay.
✦ Axolotls and drowneds attack each other. Axolotls in the water might win, so have a chunk collector or manually pick up the loot.
✦ Panda spawns in water.
✦ Cave Spider spawns on jungle leaves.
✦ Don’t bonemeal all your grass, because some mobs require grass to spawn.
