Passive coolers

[Gojak_v3]

Okay, this is probably a really dumb question. Do passive coolers have any affect if placed outside. It's just getting a heat wave is really hell on the colonists. I'm just wondering if I place a few around the home zone if they will have any affect at all? Like if I place a few around my crops for when they have to sow and harvest.

Nope.

Outside temp can't be affected.

Not a dumb question.
Passive coolers gradually lower the temperature to ~15 degrees (can't remember the exact value), but the open sky entirely negates that.

Better to place them inside your buildings, instead.

If you were using sun-lamps to farm inside an enclosed space, I'd say maybe yes - but the lack of roof means the answer is no. :-)

As said above, just put them around (inside) your base to help reduce temp. This gives your pawns a safe place to retreat to if they get too hot. Also, make some cowboy hats and dusters. Certain clothing can help increase their maximum comfortable temp.

Sure they do. You need about one passive cooler per 25 squares of cooled room.
As the outdoors( = the whole planet) is a bit large, you need a lot of coolers to have a noticeable effect. For the normal planet, about 42-43quidrillion should do the job.

As far as I've seen, it is theoretically possible to "cool your crops" by having a handful of coolers in an enclosed room where the crops are located under a few removed roof tiles. The bleed through the open tiles is proportional to the temperature difference though, so I imagine it is only feasible for small crops, like, say, 5 healroots, and not in temperatures above ~115F.

Otherwise, you would be clearcutting forests to fuel enough coolers to keep your modest plot of potatoes growing. If you're playing in an area with crop-killing heatwaves, I don't suspect there are many forests around.

Do farm zone crops now need open space?
I remember having built greenhouses, with a roof and sun lamp and cooler/heaters (depending on biome) in earlier patch states, however, it's a long time ago since I did that last time.

Imho it should work inside, if you got a sun lamp and the comfortable temperature and soil, however, I maybe outdated with that.

Because I never saw the use in building hydroponics, so I instead have built indoor farms in colder biomes to generate crops all year round.

Indoor crop fields with sunlamps do work, but tribals don't start with electricity so would need open sky over crops.

Trees need open sky due to sheer size.

Yeah, Trees as the exception, that I do know. Good to hear, it still is the case.

Yeah, Tribals are pretty much ♥♥♥♥♥♥ in that situation, basically the only thing you can do to prepare for winters/heat waves/cold snaps is to have very large farm zones, so you gather so many crops, that you got a large stock of raw food to turn into cooked food/pemmican during these times.

However, the passive coolers do work wonders inside even during heat waves, if you just build enough of them, I'm regularly surprised how well these work.
That's why I like to use them for normal climatization in living rooms in early stages of even industrial start colonies, when I'm just relying on tribal technologies mostly, since I prefer not to use Electricity before I get Fuses researched (from the RT Fuse Mod).
