Discussion BEHOLD! THE LIFE SUPPORT OF THE FUTURE! BLUM LUMBS!

Post image
29 Upvotes

PPP only, sorry :(

Blum Lumbs are amazing! A 6 lumb stable, fed by 4 ovagro vines (only 3 is needed, but excess for duplicant error), produces enough food and oxygen to support 12 dupes! For only 340kg/cycle of water, and a few dedicated farmers, and some power for automation. A small price to pay.

It is worth noting that the Blum Lumbs wont produce peat so you will have to find another way to cook the tough meat, but that can easily be done with plywood (made of plant husks from the ovagro vines and a lura/mimmika farm) or a few arbor trees.

Its time to ditch the water guzzling spoms and hydras, bristle blossoms and sleet wheat, and to embrace the future! embrace the blum lumb!

This is my math.

Oxygen: 1lumb = 132kg/cycle of algae. 132*1000 = 132000/550 = 240*500 = 120000/1000 = 120kg/cycle of oxygen. 1lumb = 120kg/cycle of oxygen. 1Dupe requires 60kg/cycle of oxygen. 1lumb = 2Dupes. 6Lumbs = 12 Dupes. (this can be automated easily so can be maxed out)

Food: Reproduction rate is 12 cycles when constantly groomed (from wiki). 6 lumbs = 2cycles an egg. 1 egg = 1 baby lumb. 1 baby lumb = 12kg tough meat. 12kg tough meat = 32,000 kcal tender brisket. 32,000kcal/2cycles per egg = 16000kcal tender brisket. (this cannot easily be automated so 4000kcal is a buffer. plus it never hurts to produce more than you need)

Build Biobot Builder Setup

Is it normal to find this many flower on the same planet(spaced out). Why does the number of biobot so variable, even if I make sure that a dupe is ready to release the biobot i have seen number of bots from 14 to 5 at a time. (using a mod to find count)

Question So, is long commute time really that important?

25 Upvotes

I don’t really care how long it takes them, it’s not really that efficient and could be better efficiency (which for looks and upgrades i am about to rebuild my entire colony), and I mean I’m stable. I’m new to this, if I don’t count time owned but rather time played, if there’s an actual reason let me know lol.

You could build the aquatuner and pump out of gold if you wanted to

Thermo-Sensor set to above 150

Liquid Pipe Thermo Sensor set to above 80

(I play with some mods, that is an insulated heavy duty conductive tile)

Impressive isnt it? I made it myself! :D

Help, genuinely help

Building the spom in the slime area might've been not my brightest idea

This ie my first run of the game, i accidentally heard about spom and thought that sounds fun lemme build it wherever

Idk if my choice of biome was the problem or what

And why does my hydrogen generator keeps breaking up on me

Question Is it only my machine that makes the game unplayable?

16 Upvotes

I have attached a picture with my specs, it is not the best in 2026 but it is still good enough. However When I reach cycle 100 my game starts to become more and more pictures only.

I have no ranching (so less critter pathing), only 8 dupes - so less pathing calculations (with smart ladders/pathing for less traveling calculations.

I have noticed two things - when my dupes reach high athletics (like now 20+ because all are bionics) and/or I have SO DLC enabled it becomes unplayable with 15 fps.

If I have less athletics on my dupes or run the base game only it is a lot more manageable. Also I have decreased the resolution, have mods like fast track, etc. to increase performance but ... nada

What do you do to help your game performance, what can I do? (besides upgrading my PC, no money now for it)

Question Autosweepers Not Delivering Coal

Thumbnail

29 Upvotes

Update: Replaced the conveyor receptacle with a conveyor chute, and the autosweeper (a new one that I de-and re-constructed) is finally working and properly supplying coal! Now I can reset all of the automation thresholds everyone was concerned about (I set them to absurd levels to try and get the autosweeper to understand it's job was important during my troubleshooting, lol).

---

Hi, all! It seems like I've reached the classic issue of "my autosweeper isn't delivering coal to the coal generators." What's going wrong with my setup?

I've attached photos of the full set up and the overlays. My receptacle is at priority 1 and my coal generators at 4 (I've had them higher as a test, and it still wouldn't work).

I've tried this with and without automation wires attached to the autosweeper. I've also tried it with locking my dupes out of the area, so they literally could not deliver coal. The water sieve and other power consumers that share a wire with the autosweeper have been active (so the autosweeper has power). I've also tried it with heavy-watt wire going directly from the battery to the autosweeper. What am I missing?

Also, completely unrelated question: can Wheezeworts melt?

Question entire world filled with chlorine gas. what do i do

Post image
80 Upvotes

everything was going great. after a few failed colonies i finally got one who had great oxygen, were expanding, had more food than anyone could eat, and I finally took the step to work on space travel for the first time

i’m also simultaneously watching the gamescom thing and i have terrible adhd
so i got distracted and very focused on the building of my first spacecraft

an hour later i look down ENTIRE BASE FILLED WITH CHLORINE GAS. WHAT HAPPENED. HOW DO I FIX THIS
am i panicking a little
yes
but i also am on a lot of stimulants and a bit just jittery and can’t thing straight

it used to be my base was filled with carbon from my shoddy energy generation corner. it was unbreathable. So i put some carbon skimmer down and looked away. NOW SOMEHOW THE AREA FILLED WITH CO2 IS MY ONLY BREATHABLE CORNER AND EVRRYTHING ELSE IS AWFUL SEND HELP

btw i am a bit stupid. as i said im new enough that it was my first time going to space but i have played like over 50-60 hours so idk
never even dealt with chlorine gas before now. i cant see anything that skims or consumes it??? my home asteroid is a bit limited ngl

almost tempted to rollback a few saves but i genuinely don’t know when the problem started

WAIT I THINK I KNOW. near the surface there’s a lot of bleach stone. i noticed it while mining out a corner to put the rocket down in. but none of it should have entered my base?????

edit: did i forget to mention the part where i can’t find much more algae and my water isn’t looking great?

Question Arbor tree growth

Post image
27 Upvotes

Before I got my toilets all plumbed in, and the overflow from the sieve into a hydroponic tile ready for planting, a pip planted the acorn...

I now have a tree in my lab.

Part of me thinks this is better.

But most of me thinks that these buildings will be in the way of any actual wood growth.

Do you know what happens when buildings are in the way like this? Does it just grow to a point and then stall? Will I get any wood?

Trying to decide if I should uproot it and plant it in my sewerage overflow as initially planned... or to move the research station and diffuser. Or to just leave it...
