Cactus and Cotton aren't in vanilla afaik

Whatever is done by mod is visible in the picture.
Vanilla only has these hydroponics, not sure what "missing hydroponics" are.

So does this add the missing hydroponics farm types then too?

I'd recommend an import whenever you add/remove mods. I tested the game without importing and it was fine.

Do I have to Import my save for it to take affect in my game?

Try it out and see if it works.

I just want to make sure your mod can work even if I have other mod's that add Hydroponics

I'm sorry, I guess I don't understand what exactly you want.

The mod I have in question is actually called "Research and Production" and it's a bit of an old mod that hasn't seen any real update's for a while now. Look it up if you don't believe me, and I'm certian that if you can spare some time to write down a response to my comment's, that you can look up a mod in the Kenshi Workshop. Just saying.

Hmm, I use general modifications mod, could be that the mod enables those hydroponics...and then my mod modifies the parameters, I've put my mod after the general modifications mod and it works fine (as it should).

Are you sure? If they are a part of the base game, I never knew, patch notes are hard to keep up to date with at times.

cotton and cactus hydroponics are already present in vanilla, and this mod does modify values of cotton and cactus hydroponics (as can be seen in image).

Here's the thing, the part that is important is that just enables you to build cotton and cactus hydroponics (among other thing's, but the rest is just for other stuff, like copper drills for example.)

No

So will this allow those Hydroponics to benefit from the feature's of this mod? Or not?

if the other mod adds 2 completely new buildings, then this mod will have no conflict or override with the other, because it modifies only existing vanilla hydroponics building parameters.

Also all I need to do is have this mod be bellow the other mod in question right?

The mod I would be using as an example would be 'Research And Production' It has a number of additonal features to the whole matter of producing stuff, among them is adding 2 Hydroponics, one of which is cotton, quite a few mod's out there just for thing's like that in fact.

Also, "Cloth hydroponics" ? A bit confused.

If you have multiple mods that affect same things, the values that will be in effect will be from mods that are the last in the mod list when you launch the game.

If you want the values of this mod to be in effect for the things visible in the picture, you must set this mod to be later in the list than other mods that may affect same values.

So does this mod affect Hydroponics that are added by other mod's (Like any number of mod's that add one for Cloth as an example.)

Intersting, nice one OP

Suggestions/Requests welcome.
I kept the mod small and simple to cause as few conflicts as possible.
