Soulwind Posted January 31, 2020 Share Posted January 31, 2020 It'll work for awhile, but you'll eventually warm up the ice biome and have it shut down. For long term you are basically required to use active cooling. Link to comment Share on other sites More sharing options...
DonDegow Posted January 31, 2020 Share Posted January 31, 2020 To expand on what Oozinator said, it won't be useful to introduce heat in your farm in order to melt the water to use that as a coolant; you're trying to heat up your coolant, with a space heater moreover which is really not a good use of your electricity (which you had problem with in another post), it will never be able to melt enough water to constantly feed 24 sleet wheats. From what I can tell, the biome is at about -30°C which is perfect for sleet wheat, why would you try to change its temperature? A better idea would be to bring water from a supply you have ready and using insulated pipes and maybe a valve to avoid heating the biome/having ice forming in your pipes.

psusi Posted January 31, 2020 Share Posted January 31, 2020 Also you shouldn't try growing sleet wheat if you are still struggling with other areas of the game. It is the most challenging crop to grow. It is much easier and cheaper to grow mushrooms, and eventually when you find a NG vent to run the gas grill, some lettuce to fry into mushroom wraps.

Neotuck Posted January 31, 2020 Share Posted January 31, 2020 There are 3 things I like to establish before building a sleet wheat farm. 1. A large stock of wheezie wort seeds 2. Dirt production (pip ranching is ideal) 3. Fertilizer production Link to comment Share on other sites More sharing options...

What, more of a problem than nosh sprouts? Anyways, the basic idea of this is not that bad, it just is time-limited as the ice-biome will slowly melt away. It is certainly usable to get some experience with the crop. Link to comment Share on other sites More sharing options...

Insulated pipes don't really help, since the water is delivered to the farm tiles, where it exchanges its heat with the environment. You can get by with 10C water for awhile, but at some point you'll need some sustainable way to produce 1-5C water Link to comment Share on other sites More sharing options...

As long as you have a good cooling system to keep the plants cool the water shouldn't heat up much.

I haven't done the math but one wheezwort per 2 sleet wheats works just fine Doing the math, knocking 66g/s (40kg/c) of water down 25C takes 7kDTU/s, and a wheezewort provides 12k, so that'll work. The risk there if your wheezeworts aren't temperature controlled is overcooling, but you've also got your dirt temperature to lower as well. Edit: That's assuming your wheezeworts are in hydrogen, if you're cooling oxygen, it's only going to provide 5k, so it may eventually warm up Link to comment Share on other sites More sharing options...

A point in favor of nosh sprouts over sleet wheat is you can easily hit their growth temperature range with a direct aquatuner loop setup, since ethanol's freezing point is so low. For using an aquatuner to direct cool water , you need to specially handle any packets between 5 and 14C, since they're too warm to feed to SW and too cold to aqua tune. 12 minutes ago, Neotuck said: I keep the wheezworts in a separate room devided by mech doors automated by a thermal sensor.

For example, if you started sending in 60C water, you'd need to double your wheezeworts. Link to comment Share on other sites More sharing options...

For example, if you started sending in 60C water, you'd need to double your wheezeworts. It really depends on what I have to work with and if I can spare power for aqua tunners. In my last game I was lucky to have 2 PW geysers (30C) I just sieved and stored the surplus before sending it to my farm. Had plenty of dirt from the sieves and I ranched some dreckos with balm lilies for phosphorite. By end game I had all my dupes eating pepper bread Link to comment Share on other sites More sharing options...

I solved this one a long time ago, but I can see how less experienced players may find this difficult. The way to do this is to mix cooling liquid with suitable low freezing point in a tank. That way the temperature changes slowly. You need to loop some of the liquid in the tank to itself to measure current inside temperature, but that is about all that is to it. Then you use that cooling loop via a counter-flow heat exchanger to cool the actual water you feed to the sleet wheat. But I admit I have used wild sleet what for ages now. A lot easier to handle and setting it up is not that much effort. Link to comment Share on other sites More sharing options...

My go to when I don't do that though is a closed loop of pWater running through an AT cooling a small supply cistern. That makes it easy to switch over to super coolant when space materials become available. But again, more complex than just sticking a fluid into an AT.

Neotuck Posted January 31, 2020 Share Posted January 31, 2020 Correct me if I'm wrong but water stored inside a hydroponic tile won't freeze. So as long as you supply the water in insulated pipes made of ceramic, you don't have to worry about over cooling Link to comment Share on other sites More sharing options...

So as long as you supply the water in insulated pipes made of ceramic, you don't have to worry about over cooling I think if it's cooled down while it's in there it's fine, but I do think there can be weird situations where it transitions from the insulated pipes to the tile. But in any case, if you're overcooling, you'll eventually drop below -55C and the sleet wheat will stop growing. Thinking about it, it's actually really weird that a plant can live in temperatures 55 degrees lower than the fluid it lives on freezes at.

If you aren't using one valve per farm tile to limit the in flow to only what the plant takes, you have 5 kg of 30 C water sitting there exchanging heat with the tile. It constantly has 66g/s being deleted and replaced with fresh 30 C water, so it will reach equalibrium somewhere below that, but not all the way down to less than 5 C. 2 hours ago, hackcasual said: Insulated pipes don't really help, since the water is delivered to the farm tiles, where it exchanges its heat with the environment.

So as long as you supply the water in insulated pipes made of ceramic, you don't have to worry about over cooling I've had it freeze. There is thermal transfer between the environment and the contents of the hydroponic tile based on the insulated properties of the material used for the tile. In the case where I had freezing, my hydroponics tiles were at -15c and the water coming in was only at 2c. The insulated pipes near the end of the wheezewart line broke. I tested the same flow rate scenario with pipes and no hydroponics tiles and the pipes didn't break because the temperature of the water in the pipe never got cold enough. I think its a similar issue to when you boil water (or petrol) in a metal refinery. The pipe at the refinery's output breaks. The water turns to ice as its entering the hydroponics tile and causes the pipe to break. I should add: This was a large thermal difference. With the room even 5c warmer the problem didn't occur.

No; with those you are heating it to boiling inside the machine, which the machine does not care about. As soon as it leaves the machine and enters the pipe, that's where it flashes to gas and breaks the pipe. If you use a valve to limit the flow to 1000 g/s then you can heat water to above 100 C in the pipe without it breaking and feed it into machines, like the electrolyzer, and the machine doesn't care that it's over 100 C Link to comment Share on other sites More sharing options...
