As some might know, 1 scrap plus 1 fertilizer= 2 fertilizer. I personally think its OP, but can there be a config option to disable this! It could mean endless fertilizer.
Fertilizer just NOT much make faster growing. For stopping that, what's wrong is here Weed - Ex, so... It's NOT OP i think. I truly good
It should be bad if it was able to turn back into bone meal, this way, only scrap for agriculture... What exactly is OP?
I would use the Scrap for UU Matter, and take a completly free Skeleton Spawner for fertilizing the Crops. Bonemeal works on IC² Crops.
