As things stand, Weed Fields seem to mostly produce a loss, especially without the education.

Whether through increasing sales price or quantity produced, making them profitable would make them go from a beginner trap to a useful early investment.

It's very profitable early on when you grind your own fert. After you are high enough you just focus on your better productions.

It's fine for now, we just need some nolivers to grind thousands and thousands of fert like people did in the past.

Market crashed to 7k each.

It will happen again one day

If you are spending more in fert value than the money you get, it's not profitable. One could just sell the fert.
