This page is a longer and more technical version of [[IC2 Crops Guide]], which covers the math, automation and detailed mechanics of IndustrialCraft 2 crops.
* For a list of crops, see [[IC2 Crops List]].
* This page assumes a full familiarity with the beginner concepts covered by [[IC2 Crops Guide]].
== Automation ==
All IC2 crops can be automatically harvested for their resources when they reach their final growth stage with right-click, and return to an earlier stage without needing to be replanted. [[Automated Farming]] machines will harvest crops in exchange for power and resources without player interaction, with the exception of Ender IO's [[Farming Station]] which is not compatible with IC2 crops. Crop stat gain can be fully automated with [[Open Computers Crop Breeding]] in Late HV/early EV.
The [[Crop Harvester]] from IC2 will harvest crops, but not fertilize or hydrate them and it will attempt to harvest plants as early as possible, potentially before they reach full maturity (e.g. Oreberries, Stickreed). For crops with high stats it needs to be paired with a [[Crop-Matron]] and a large supply of fertilizer and water or they may die, depending on [[biome]] and elevation.
The '''[[Multifarm]]''' waters, fertilizes and harvests, but has no slot for Weed-Ex. It requires Uranium238 Electron Tubes in an Intricate Circuit Board to operate with IC2 crops, which extends its range up to an eleven radius octagon covering 1149 blocks (1136 after water blocks are placed). While the Multifarm will only handle a single layer of crops, it can be powered by RF generators such as EnderIO's Photovoltaic Cells effectively for free. This makes it convenient for farming operations far from a main base. Unlike the Crop Manager, Water and Fertilizer are not optional with the Multifarm.
▲Be careful that you do not place seed bags with high stats onto crop sticks that your Forestry farm or Crop-Matron hasn't yet fertilized and hydrated. They could possibly die before the machine even gets to them.

Historically the '''Crop Harvester''' and '''Crop-Matron''' were paired together for IC2 crop automation. They each use 1 LV amp to run continuously, and together they need 2 amps to keep all crops growing fast and harvested constantly, but were less expensive to craft than the Multifarm for small applications and at a lower tier. They have been superseded by the '''Crop Manager''', which does both tasks in one block. The Crop Manager can handle three levels of farms if placed as shown to the right (just above the dirt of the middle level). Horizontal range varies with the tier of the Crop Harvester, and a few blocks are likely to be sacrificed for hydration and power delivery infrastructure. It is possible to replace dirt with fertilized dirt removing the need for water.{{clear}}

== Weeds ==
Weeds are a crop that will spread to empty crop sticks and destroy many other crops. Weeds and weed-like crops with higher growth stats attempt to spread weeds more often. Weeds can be removed using a Weeding Trowel or a Crops++ Spade or by breaking the crop stick and replacing it. Normally, weeds will only naturally spawn on empty crop sticks or double crop sticks. This means that you only need to watch for weeds while cross-breeding; once you have a full field of crops being automatically harvested, weeds will no longer be able to spawn. Weeds also spread normal tall grass to adjacent grass blocks.
However, there is an exception to this. Normal crops with 24 growth or higher are also considered weeds (or "weed-like") when they are at a growth stage of 2 or more (Venomilia, an exception, is weed-like when it is at its 5th growth stage and it has a growth stat of 8 or higher). Specifically, this means that the crop will attempt to spread weeds (real weeds, not copies of themselves) to adjacent empty crop sticks or to other crop sticks that do not contain weeds, overwriting any crops inside. However, other weed-type crops are immune to this effect. Because some crops do not revert all the way to their first growth stage upon harvest, this means that a standard, flat, fully filled field can contain a stable population of automatically harvested high-growth crops without needing to apply Weed-EX if the following conditions are met:
Line 47 ⟶ 65:
-Once the decline is triggered, one stat is randomly chosen and that stat is permanently reduced by one point. There is a 20% chance for Growth to be chosen, a 20% chance for Gain to be chosen, and a 60% chance for Resistance to be chosen.
-Also contrary to popular belief, use or overuse of Weed-EX will not trigger any kind of 'flag' to be genetically passed down in the crop's NBT data. Weed-EX does not affect crop breeding, and no data related to Weed-EX is stored in a seedbag's [[NBT]] data. The only possible negative effect of Weed-EX is the stat reduction described above.
When it comes to usage strategy, Weed-EX can be indiscriminately applied to a breeding field to prevent weeds when a player is breeding plants with growth stats of 23 or less. When working with plants with 24+ growth, care must be taken not to apply Weed-EX (at least not to beyond 75) to plants at their second growth stage or higher. Weed-EX can still safely be applied to empty crop sticks (in preparation to plant or to crossbreed) or to crop sticks containing plants at their first growth stage. It is recommended to do so, because if Weed-EX is not used in this case, weeds are very likely to destroy those crops before they can grow.
