Even with the Just the Pepper mod installed, an warning (?) occurs during world creation.

@ Vigilance but does it increase nutrition consumption? I have heard that someone extended the growth time but it caused the soil nutrition to regenerate faster than it depleted (i assume growth speed is linked to nutrition consmtion), removing the need to rotate crops 

There is actually a setting for this, for what its worth. You would just use the command "/worldconfigcreate double cropGrowthRateMul (value)" with your value (in this case, would be 0.5) at the end. After a server restart it will take effect on all crops, you can see the timer on a seedbag change. A mod like this is great for people who are spooling up new worlds frequently or would forget to set this config though.

CleverMagpie Should be no problem adding or removing the mod in an existing world. It won't harm your existing crops.

Crazy! I was just thinking I wish that there was a setting for this. Thank you for the make and the share :)
Will it be ok/safe to throw it in with a save that currently has plants in the ground or should I wait to activate it for the next time I plant stuff in the ground?

could you possibly make this compatible with the new word crop mod and or the bell pepper mod?

Please and Thank you.

I noticed that the soil nutrients used by crops with this mod is less than the nutrients used in the base game.
Based on my test, vanilla flax consumed 35.3 K (after 19 days of growing), while flax with this mod consumed 25 K (after 39 days of growing)
I suspect that it consumed the same ammount in both cases. But due to how long this mod makes them take to grow, the soil had time to regenerate some of its nutrient level.

but it still takes more time, well, the bushes atleast changed

I tried that command but nothing seems to have changed , the crops still show the same growth days on the seeds

Instead of downloading this mod, try writing this command in chat

/worldconfigcreate double cropGrowthRateMul 0.5

(default is 1, range is 0.1 to 10)

But it also alter berry bushes.

Oh my bad. I misunderstood. I made this for myself and I have no interest in crops growing faster... That said, it would be easy for you to edit my mod to do that for yourself. Just change the "value" in each json file within the zip to 1/4 it's current value and your crops will grow lightning fast.

Nono the other way around, a mod which makes the grow time shorter. Sorry for confusion

AzzAzf As of 1.19(?) the grow times are based on months and not days, so the growing time will scale to calendar length as is. This means regardless of how many days your months are, this mod will make any crop generally take most of the growing season to get a harvest, with the exception of maybe turnips which naturally grow very fast. If you were to increase the grow time any more than 2x you'd struggle to ever get a harvest before winter.

Could you make a version which doubles or triples growth speed for games with long month times?

No, the script that controls the time it takes to grow is unique to each crop.

Does this work with mods that add new crops?
