When water goes on top of grass blocks, it turns them into dirt blocks way too quickly and automatic flower farms that dispenses bone meal into a grass block to grow flowers, and then have water break the flowers don't work because the grass blocks turns into dirt blocks, and you can't bone meal dirt to grow flowers

Eventually every grass block will turn to dirt and make the farm stop working, if the grass block the dispenser is under turns to dirt first then the farm will break straight away.

A way to fix this problem is by making grass blocks take longer too turn into dirt blocks, I think it should take 10 minutes for it to turn to dirt blocks, this will give players freedom on making farms.
