Simple Pepper Bread Plantation.

[MustardWarrior]

I came up with what I consider to be a good design for providing enough pepper bread and also daily espresso for 10 duplicants without the farmer bonus.  This post is much more verbose than it needs to be so if you know what you're doing you can just skip the rest and look at the image and see what's going on.  This was done in debug mode but it's easy enough to build in survival mode and I think it will require like 5 tons of refined gold. So not exactly cheap but not ridiculous, you could save about a ton if you make the pipes irrigating the pepper plants regular pipes, but then you might use more energy pumping to heat up the room it might not be worth the gold to you.

The sleet wheat room is pretty simple no automation, chilled polluted water gets piped in from the aquatuner through gold radiant pipes along the sleet wheat, utilizing it's handy -20 degrees Celsius freezing temperature.  while insulated pipes pipe in water from the cold water tank to the 25 hydroponic farm tiles.  I don't think it's necessary to monitor the way I see it, the amount of heat leaking out of this room is so small that effectively to cool it down further than it needs to is basically a one time energy cost and it's good to have a safety margin.

The middle left room is the polluted water tank, no automation in here either just a pump, the aforementioned aquatuner which is configured to not require a pump once the pipes are full of polluted water, a deoxidizer to deal with polluted oxygen and a liquid vent which the water used to heat the pepper room empties out into.

The room middle right room is the cold water tank, this tank is cooled by the aquatuner after the water has already been used to cool the sleet wheat room.  Obviously there is a pump in this room to irrigate the sleet wheat. and there are two sensors the pipe thermal sensor to prevent the aquatuner from freezing its coolant and a thermo sensor to prevent the cold water tank from freezing and an AND gate so that it has to meet both of these conditions.  If you chill the cold water tank below 5 degrees C you remove the main source of heat from the sleet wheat room and when it reaches 2 degrees the aquatuner is disabled and the cold water tank will cool the sleet wheat room on its own and the pump is the only heat source for this room so it should stay off for a while.   The size of the tanks were selected based on the fact that pincha pepper use 35 kg/cycle while the sleet wheat only use 20.  Under most conditions it's really easy for the aquatuner to freeze the polluted water coolant so for smooth continuous operation and therefore reliable cooling you want something with a large mass to heat up the coolant before sending it back into the aquatuner that's why it's necessary to run the piping through the cold water tank and it's really important that it go through the sleet wheat room first because of the freezing point of water. 

 

The bottom room is the pepper room and it functions much the same as the sleet wheat room except in this case there is a liquid shutoff which shuts off flow to the heating pipe when the thermo sensor reaches a high enough temperature for the pepper plants.

 

This was done in debug mode but this seems easy enough to build.

 

Crap I just realized the UI blocks the thermo sensor in the pepper room, one of the plants is moved upward to make room for the thermo sensor also I just realized it's 1 tile too short to fit in with the typical 4 tile high rooms.  I would add a tile to the bottom room to make room for auto sweepers, which I didn't include in this build so that it was simpler to understand..

Where do you get the polluted water for this? And how much water does it consume?

he said debug so most likely he spawned it in

But in a real oni situation, would you just tap into a geyser?

unlikely, it would take time to get the temperatures right

Personally I think the OP design isn't very practical

Sleet wheat is hard enough to grow if you don't have nearly freezing water. I don't see running both on the same line as being feasible - you would need two aqua tuners to even meet the proper thermal delta. This particular design is eventually going to completely fail if it continues to circulate the polluted water like that....even with fresh input.

On top of that, almost no natural sources of water are hot or cold enough to feed these things directly. When passing water through a sieve for purifying or so on the output almost always favor heat over cold.

...or wheezeworts

I have been able to feed 26C water to my wheat farm without having to worry about it heating up my crops

[MustardWarrior]

For both the water and polluted water I switched degrees to kelvin and looked at the closest pocket of water and polluted water and copied their respective temperatures and painted in the each of the tanks at 1000 kg per tile. And the sleet wheat was growing almost immediately and the peppers took a few cycles to heat up.

 

Here's some math on the heating/cooling capacity of the aquatuner.  For the (at most) 27 tiles of fresh water you have:  27000kg of water okay how much will the aquatuner cool it?  10kg packets * 14 degrees *600 seconds = 84000, 84000/27000 = 3.111 repeating degrees per cycle, that is plenty for water starting at 22 degrees.  I'm on cycle 10 and the polluted water going out of the aquatuner is at -14.4 and the polluted water going into the cold tank is -13.6 so almost all of the cooling is going into the cold tank.  As for heating well it heats as fast as it cools and in the swamp biome the water starts at 30-35 degrees.  So it only has to heat few degrees degrees and the pump is right next to the aquatuner. and the aquatuner is going to heat the polluted water at 84000/51000 = 1.6 degrees per cycle.  Peppers grow at 35 degrees.

 

As for where you get the water.  Well it's all over the map in the swamp biome there is so much of it.   Oil Wells give you like 500g/s net water if you convert it all to natural gas.  Geysers/ cool steam vents.  I think it's possible to make this sustainable.

Even if you are adding sieve water to the tank at rate the sleet wheat consumes you are only talking 20 kg per tile *25 tiles or 500 kg total. The aquatuner cools 84000 kg/degrees per cycle so even if you have to cool it down by 38 degrees per cycle that's 500*38 = 19000, or 19000/84000 = 22.6% of the aqua tuner's cooling capacity.

It's really just a matter of getting it to run consistently without freezing the polluted water and that's why you run it through the cold water tank before sending it back into the thermo aquatuner.

This is my pincha pepper farm more simpler and more efficient. I use the polluted water from the toilets and a little supplement from the algae distiller .

[Gurgel]

The problem is the pwater, not how to design a farm around it.

[ChickenMadness]

As long as theres a slush geyser on the map it's incredibly easy to double up with gulp fish & sleet wheat like this. 

gulp fish make ice > ice feeds the sleet wheat.

I play without any slush geysers i  can make polluted water from space solid CO2 ...and water

Here's my attempt at a Sleet Wheat farm...

Wheezeworts in O2 are not that good. You can improve your design by switching your wheezeworts in a room of pure hydrogen and then piping a liquid or a gas to cool the farm. Each wheezewort will net you a lot more cooling this way. 

But nice setup!

you will run out of dirt.  a farm this large requires massive dirt production

Yea, I usually drench them in hydrogen. But in this case I didnt want to have to build a whole seperate building with wheezeworts and hydrogen circulating around.

Thank you tho!

Have you thought about placing the wheezeworts between the farms like in my picture?

They are in hydrogen and cool the farm tiles so well that I can irrigate it with warm water

I will try that my next build then when they fully release MK2 today. Does your build HAVE to have that many Wheezeworts? Have you tried it with less and does it work? I would hate to use almost all the Worts on the map for just the Sleet Wheat lol

Depends how warm your water is

Also I had an ice world were I got most of my wort seeds

[goochmyster]

Very nice... I will def try it out then, Thanks!
