Greenhouse

How the Greenhouse works

• The Greenhouse is a Garden plot unlocked at Garden Level 7, after completing the Carpenter visitor's offer and getting the Greenhouse Blueprint.
• Crops in the Greenhouse grow while the player is offline, need watering, and are harvested once mature.
• Each crop gives its Crop Effects to crops in the 4 orthogonally adjacent slots (not diagonals), never to itself.
• Effect values: Harvest Boost +20% yield; Improved Harvest Boost +30% yield (replaces Harvest Boost); XP Boost +20% farming XP; Improved XP Boost +30%; Water Retain +50%; Improved Water Retain +100%; Harvest Loss -20% yield; XP Loss -20% farming XP; Water Drain -30% water.
• Immunity blocks negative effects; Effect Spread passes a crop's other buffs and debuffs on to its neighbours; Bonus Drops makes harvests also roll the Harvest Bounty pool.
• Harvest Bounty pool: Burrowing Spores 0.2%, Ethereal Vine 5%, Evergreen Chip 3%, Iridium 0.2%, Overclocker 3000 0.05%, Overgrown Grass 0.1%, Synthesis Chip 3%.
• Base crop yields and effects: Wheat 72 (+1 Seeds), 8 stages, Harvest Boost; Carrot 175, 8, XP Boost; Potato 150, 8, Immunity; Pumpkin 68, 11, Bonus Drops; Sugar Cane 136, 8, Improved XP Boost + Harvest Loss; Melon Slice 320, 11, Water Retain; Cactus 132, 8, Improved Water Retain + Harvest Loss; Cocoa Beans 120, 6, Immunity; Red/Brown Mushroom 30 each (unconfirmed), 6, Improved Harvest Boost + Water Drain; Nether Wart 108, 8, Improved Harvest Boost + XP Loss; Sunflower 232, 15, Bonus Drops; Moonflower 232, 15, Bonus Drops; Wild Rose 200, 15, Effect Spread.
• Every base crop gives 320 Farming XP when harvested.
• A growth stage takes 4 hours at baseline; timer in seconds = 14400 / (1 + 0.025*unique crops + 0.0025*Crop Growth + 0.001*Greenhouse Speed attribute + 0.05*growth-speed upgrade tier, or 0.50 at tier 9). Fully boosted it is 1h 41m 3s.
• Each unique non-mutated crop growing in any Greenhouse gives +3% yield and +2.5% growth speed to all crops, up to 12 types (+36% yield); Sunflower/Moonflower count as one type, as do Red/Brown Mushroom.
• A crop loses 2-3 water per growth stage; with negative water it may fail to advance a stage; at -100 water it becomes a Dead Plant.
• Effects on a crop are locked in at the moment it first becomes harvestable.
• Yield buffs are additive, except Evergreen Chip (+2-60% base crops), which multiplies and only applies to base crops, not mutations. The Plant Yield upgrade gives +2-20%.
• Mutations appear on an empty soil slot when the right crops surround it within 1 block; the Mutations list gives each mutation's growth surface (Farmland, Soul Sand, Sand, Mycelium, End Stone, Dirt).
• Spawn chance uses staff-quoted weights (mostly 30 for common, 25 for most others, 20 for Devourer/Glasscorn/Phantomleaf/Timestalk, 6 Lonelily, 5 Godseed, 0 for special cases) scaled by how many of the surrounding blocks are crops; Dead Plants and Fermento count as crops, Fire does not.
• For multi-block mutations (2x2, 3x3) the required counts refer to occupied blocks around the whole area, so one large mutation can fill several of the needed blocks.
• Most fully grown mutations decay into Dead Plants after a few days (shortest 3 days); some never decay, e.g. Fleshtrap, Magic Jellybean, All-in Aloe.
• Harvesting a mutation can drop an Ethereal Vine, used to unlock more Greenhouse slots and then a 2nd (100 vines + 10 Compost Bundles) and 3rd (150 vines + 20 Compost Bundles) Greenhouse.
• Mutations can be analyzed in the Crop Analyzer (Underground Lab or by phoning Jake) for Copper; the first analysis gives bonus Copper and counts toward the DNA Analysis milestone.
• Mutations fit in the Mutations Sack, whose recipes unlock at DNA Analysis Milestones I, III and V.
• Jerryflower is also listed as a mutation (grown from a Fertilized Jerryseed, 10 stages, no effects).
