Weak sprinkler

[zVince]

I was very happy to see that my suggestion was heard (it may have been mere consciousness, and the development team didn't read the post), but in any way I think it's cool the idea of some plants only grow if they only have the radius of the active sprinkler. 

But I think the sprinkler is in need of a buff, its biggest problem is that its fuel ends very fast, in one day I believe, then when I leave the camp and return the plants are dry and the sprinkler without fuel.

Solution: Make the sprinkler last more days 3-4 days, as a result it requires much more fuel.
