I don't get how slow MFR farms can be without fertilizer. I needed some nether wart and there were only 2 around my base. So I quickly built a 3x3 MFR farm and planted the 2 nether wart about 24 hours ago. Within a couple of hours, it had already gotten to the point where 6 of the 9 blocks were filled. So I figured I'd wake up this morning to nether wart. Nope. Woke up and all 9 blocks had partially grown nether wart, but none had actually matured yet. Fine, maybe something will be finished in 10 more hours.
Nope. Get there now and the nether wart is still all partially grown. None has been harvested yet.
WTF? Shouldn't an MFR nether wart farm work faster than this?
