Line 32:
A population of bacteria in a closed system, also called ''biomass'', will grow according to a sigmoidal population curve (right), where growth rate is initially slow due to a small starting population, increases in rate as the population increases, and then slows again as the resources of the environment become too scarce to support such a large population. This last concept is known as the environment's ''carrying capacity (K)'', which is the maximum amount of bacterial biomass the system can support. In GT:NH, K is dictated by the size of the Vat's output hatch.
In order to keep the size of a growing population stable, bacterial biomass must be removed from the machine as fast as the bacteria are replicating. Therefore, to maximize the production of the Vat, the bacteria must be maintained at the population that gives the highest growth rate. This is illustrated on the curve, where the growth rate can be seen as the steepness of the slope of the curve. At a biomass of ½K, the curve is the steepest and so the rate at which the biomass can be drawn off without reducing the population is the highest. Mechanically, this manifests as the Vat
One way to keep the output hatch exactly half full is using volumetric flasks and a machine controller cover. Place a fluid detector cover on the output hatch set to emit redstone when at or below half full. Set up an item conduit between the output hatch and a super tank. Set the conduit to extract from the super tank on redstone OFF, and extract from the output hatch on redstone ON. This ensures that the volumetric flask will only transfer exactly one recipe's worth of output. Also send the redstone signal from the fluid detector to a pulse former, and the redstone signal from that to the machine controller. Run the recipe manually until you have the output hatch at least half full. Then juggle around the fluids until the volumetric flask is in the OUTPUT slot of the super tank and the output hatch is exactly half full.
Now, whenever a recipe finishes, the output hatch will go from at or below half full (fluid detector cover active, conduit extracting from output hatch) to above half full (fluid detector cover off, conduit will extract volumetric flask from super tank). Then the output hatch will auto fill the volumetric flask with exactly one recipe's worth of output, switching the fluid detector back on. This will allow the volumetric flask to be pulled out again, and since the redstone went off and on again the pulse former will activate the controller for one tick, so it will begin another recipe, but wait to begin the next one until the output hatch has been restored to half full.
=== Radiation ===
Line 38 ⟶ 42:
Some recipes require very specific different sievert levels. Instead of having to hunt for a different material for each of these recipes, a shutter can be closed to block some of the radiation to reach a more customizable value. Using a screwdriver on the radio hatch will open the radiation shutter interface, where up to 100 Sv of radiation can be blocked. Note that blocking radiation does NOT make the radioactive material last longer.
=== Usage Strategy ===
If any of the science for the Bacterial Vat went over your head, then this is the section for you:
* The recipe in NEI shows you the ratios of input fluid consumed to output fluid produced.
* For a 1:1 input/output fluid recipe ratio, the input hatch should be at most 1/2 of the output hatch's capacity
* Empty the output hatch to roughly half of its capacity. (You can use Fluid Detector covers for this.)
* The processing time is the same as depicted in NEI, before overclocking rules apply.
* The starter culture goes into the slot in the controller, the circuit goes into an input bus.
