Crop Spray

Your construction robots water and fertilize the plants of the agricultural towers you mark, so they grow faster. No new buildings, no new robots.

Mark your agricultural towers with the spray planner. Whenever a tower plants a seed, a construction robot flies over with a barrel of water or foliar spray and sprays the young plant once. The plant's remaining growth time gets shorter, and the robot takes the empty barrel back to the network.

Features

• Spray planner. A shortcut-bar tool, like the deconstruction planner.
• Drag: water the selected towers' plants.
• Shift-drag: spray them with foliar spray instead.
• Right-drag: stop spraying.
• In alt mode a marked tower shows the barrel it gets.
• Two sprays.

A yumako or jellynut plant that takes 5 minutes is ready in 4 minutes with water and 3 with foliar spray.
- Your robots do the work. The spraying is an ordinary construction job: robots take the barrels from the logistic network.
- Barrels come back. The robot carries the empty barrel home to a storage chest.
- No alert spam. A plant only gets a spray job when the network has barrels; when they arrive later, the waiting plants are sprayed then.
- Gleba-style foliar spray. It spoils back into an empty barrel in 30 minutes, so brew it close to the farm.
- Works with any plant grown by an agricultural tower: yumako, jellynut, Nauvis trees, and plants from other mods.

How to use

1. Research Irrigation (after Agriculture, Construction robotics and Fluid handling).
2. Put water barrels in a storage or passive provider chest in the robot network that covers your farm.
3. Take the spray planner from the shortcut bar and drag it over your agricultural towers.
4. For foliar spray, research Foliar feeding (after Agricultural science pack), brew foliar spray barrels in a biochamber, and shift-drag over the towers.
5. Keep a free slot in a storage chest for the empty barrels.

Good to know

• Every plant gets one spray per planting. Marking a tower again with the other spray only affects plants that haven't been sprayed yet.
• The tower's crane is the limit: one tower can harvest at most about twice its usual yield, however fast its plants grow. Water gives about +25%, foliar spray about +65%.
• A barrel that arrives at a grown or harvested plant goes back full.

Requirements and compatibility

• Required: Space Age.
• Optional: Krastorio 2 Spaced Out. Foliar spray is then mixed in the chemical plant from water and Krastorio 2 fertilizer (nitric acid and biomass), needs the fertilizer research, and doesn't spoil.
• Factorio versions: 2.0 and 2.1.
• Remote interface for other mods: remote.call("crop-spray", "mark_tower", tower, "water" | "foliar") and remote.call("crop-spray", "unmark_tower", tower).

Settings

• Watering: growth time cut (map setting, default 0.2)
• Foliar spray: growth time cut (map setting, default 0.4)
• Foliar spray: spoil time (startup, default 30 minutes, 0 = never)
