Working sleet wheat farm?

[El Patron]

Hi guys. I have over 1100 hrs in this game, but I still cant figure it out how to build a working sleet wheat farm. If I build it in ice biome, it works only as long as the Ice doesnt melt. Once it melts, temperature of my sleet wheats pots raises and the farm is ruined at the end of the day. I have tried build it around Anti enthropy cooler (or whatever its name is) but that doesnt work either. Even water cooling in thermo aquatuner didnt help, because I had more problems with cracking water pipes due to low temperatures of flawing water. Even when I used a valve to decrease amount of flowing water. I noticed the most damaging thing for my plants is when my dupes bring dirt over. The dirt is warmer and everytime they put a dirt into a pot, the temperature raises. So I built a storage bin inside the farm, but didnt help that. Because my dupes bring the dirt from other places anyway. Is there any good video/manual how to make log time working sleet wheat farm? Thank you.

There are other liquids you could use as a coolant. Use the in–game encyclopedia to find them. Which coolant is best depends on the application, but for something that is cold you want something with a lower freezing point.

You could also use gasses in a cooling loop, though not directly with a thermal aquatuner.

Well, that gives me some ideas. I could use petrol for cooling using Aqua tuner. And since its freezing point is about -50 celsias, that means, I shoudnt have the problem with cracking pipes in Aquatuners station.

There is no need for that - sleet wheat tolerates 5C, which means that the liquid will never have to be colder than -9C which means that polluted water will do fine, and even salt water could be used in an emergency.

If you have problem with pipes cracking then the aquatuner isn't built right and it will keep breaking regardless of which coolant you use.

Even when I used a valve to decrease amount of flowing water. I noticed the most damaging thing for my plants is when my dupes bring dirt over.

Some amount of heating is unavoidable if you want to grow domesticated plants that use fertiliser and you will just have to run the aquatuner more; however, you should not store your dirt in your farming area because you don't want to cool down dirt unless you absolutely have to (but you would have to ask a heat multiplication expert to be sure).

Or you could just run the fertilizer in on rails, which will allow it to cool before it is used.

Question , is the plant heat is based on the plot tile or the air around it ?

Correct me if I'm wrong, but I think it's based on the temperature of the plant itself, which depends on both of those.

You shouldn't care about your plant temperature.
Only care about the gas (type, temperature, pressure) behind them.
Gas do heat transfert to any tile/liquid/gas (beside vacuum) next to it, and to stuff in the background (pipe or rails for example). Excluding the tempshift plate here, cause it's kinda special.
Since most tile transfert heat slowly they aren't a big issue as long as you can offset the small amount that get transfered. I think the worse would be granite a little over 3DTU.
And usually you wouldn't mind have some heat transfer since you kinda want to cool off your base anyway in one way or another at some point (since you tend to produce heat overtime), unless you tend your wheet farm next to a volcano or smth.

If you are going to use an aquatunner, rune the pipe that go to the inlet one tile further and make a bridge from it to the pipe connected to the outlet. Then add some automation to check the temperature of the liquid in the pipe before the inlet and disable the aquatunner if it's too low (freezing point of your liquid +14°c for example, since it reduce your liquid temperature by 14°c).
This way the flow keep going and heat transfert in your farm keep going, but if a liquid in your pipe is getting hot it will get cooled (assuming you deal with the aquatunner heat in another circuit, like using a steam turbine).
if you want to avoid spike heat in your farm you can run the pipe going out of the aquatunner in a few metal tile and send the material required for the farm (rail, liquid in pipe) trough them.
I can cool 800°c metal moving on a rail to 15°c with just a handfull of metal tiles, you really don't need much of them - just don't run the end of your piping (cooling the plant) near it, since you want the end of your pipe hot so the aquatunner can take the heat from it.
That's probably overkill though.

Sleet wheat is annoying to grow. Aqua Tuner cools liquid by 14C while there is a 5C difference between the stifling of the wheat and the freezing point of water, which you need to grow the wheat, which is dumb. You are better off growing them wild. I've grown it in hydroponic tiles fine before, but with some hassle in the long run, though there are ways to optimise the growth.

Plant heat. But the temperature of the fertiliser or liquid you put into the plant boxes can easily exchange with the plant even if you are putting in grams at a time. This is also why growing sleet wheat is annoying.

Farming sleet wheat can be really easy, even when using boiling water.

Here is a farm I just made:

https://steamcommunity.com/sharedfiles/filedetails/?id=2598295808

https://steamcommunity.com/sharedfiles/filedetails/?id=2598295846

It is a fully automated farm, feeded with 97C water and 75C dirt.
Automation counts 18 cycles, during which water and drit is supplied. After that 18 cycles the supply is stopped for 4 cycles and after it pass crops are automatically dropped and picked up by autosweepers.

The farm is cooled down by 29% uptime aquatuner, running polluted water. Sensor is set to pass the water via aquatuner if it is hotter then -8C. Aquatuner is cooled down by self cooled steam turbine.

If you wish to see it working live then here is a save file:

To start it just turn on the swith next to door under liquid reservoir.

"Really easy", *proceeds to show an advanced contraption aimed at using exploits*

Just find it a little amusing.

[Angpaur]

What kind of exploits you see there?

And you can consider it advanced if you want to fully automate it. Otherwise, if dupes labor used, the overall complexity is rather low.

Thanks for the save file. I will take a look. But I can see on the picture your wheat is dried out. So it doesnt look like its ok. Or is the picture just misleading?

[Angpaur]

It is not dried out - it is ready to harvest. It will stay like this for 4 cycles, while no more water and dirt are supplied and then crops will be auto dropped.

[El Patron]

And is it automatic harvested too? Because as long as I know you always need a dupe for harvesting. Or am I wrong?

[Angpaur]

Yes, if no dupe harvests it within 4 cycles then it will auto drop. It is true for all harvestable plants.
