[MCPE-48007] Sugar cane takes forever to grow.

Like I said, it takes way too long. Almost two years ago this same problem was still in the game and a user reported it here as well.

MCPE-23749

There's the link for it

It appears that the bug came back?

it grows fine for me if its taking to long for you u can allways use bone meal on it thats a thing in bedrock mc

Alex Chu 2019-07-03T08:17:16Z

@monkeybee do you have an idea on why it's happening to me?

Don Cox 2019-07-03T21:44:44Z

@Alex Chu is it a multiplayer world/realm or a solo world?

Euwill Eusebio 2019-07-04T01:11:49Z

Unable to reproduce, the sugarcane grows just fine under 10min. Perhaps you are too far away all the time from the sugarcane to actually grow.

Alex Chu 2019-07-04T03:13:04Z

@Don Cox it's singleplayer.

@Euwill Eusebio is 40 blocks too far away? I'm 40 blocks away from it (still seeing my sugar cane farm very visibly) and it's still not growing under ten minutes.

Also waited ten minutes while standing near it and only two sugar canes updated one block higher out of my other sugar canes.

Depends on the Simulation Distance. unless you've set yours to 2 chunks, I don't see how this wouldn't work.

Alex Chu 2019-07-05T10:19:02Z

@[MCPE Helper] LateLag i was standing very close to it so 2 chunks would still work, but it doesn't. my simulation distance is always at 12-10 chunks

Don Cox 2019-07-06T00:02:58Z

I know this is an older issue, but @Alex Chu does MCPE-48007 kind of sound like the issue you are having?

Morgwenna 2019-07-06T10:59:43Z

I agree.. cane growth rates are so painfully slow so you end up having to have huge fields of the stuff just to be able to do initial trading with librarians. I try to make full use of composers and, hopefully, a skeleton spawner and use bonemeal whenever I can.

[Mojang] Mega_Spud (Jay) 2019-07-25T11:00:59Z

Do you have any comparisons as to how this compares to the Java Edition, for example? (As far as I can see they grow at a similar rate, which can seem like a long time when you are waiting for it to grow!)

[Mod] OcelotOnesie 2019-10-21T12:31:41Z

They certainly don't grow at a similar rate for me. In Java Edition, the sugar cane I plant always grows within 5-10 minutes. In Bedrock, it takes at least over 30 minutes just for it to grow one stage.

Pig2Creeper 2020-06-14T03:15:11Z

because the randomtickspeed is 1 on bedrock and 3 on java, it is very slow. also, yiu have to be within simulation distance *deafauld 10 on win10"

GoldenHelmet 2020-06-14T19:22:08Z

I think there could be an issue here with random block updates being suppressed in certain situations. The video I posted to confirm MCPE-81628 shows that when placing a row of grass paths under other blocks with randomtickspeed = 1, every other grass path converts to dirt. But on randomtickspeed = 4096, every grass path converts to dirt, though not instantly as you’d expect. What I’m wondering is if a block update that triggers a block update next to it causes the next random block update on each surrounding block to be skipped. I’ll try to work out a way to test this.

Update: Negative. Tested by planting sugar canes in different arrangements so that either 0, 1, or 2 other sugar canes were adjacent to them, and also allowed some to grow naturally next to sugar canes that had be force-grown with bonemeal. Did not observe any differences in growth among setups.

I've attached a video of

[media]

In it, I have the random tick speed at 410, which means that on average every block should get ticked once every half second. Repeating command blocks replace the sugar cane with new plants once every 23 seconds, long enough to let it grow to full height in most trials. In the video you can see a regular pattern of growth every 7-11 seconds. This implies 2 things:

The overall chance of growth each time a sugar cane block gets ticked is about 5%. (At 410 tick speed, 7-11 seconds = 14-22 ticks on average for a sugar cane to grow one stage.)
Growth is not truly random. It's more like random after a set delay, or random with a declining chance of failure over time.

This actually matches what the wiki says fairly well: that sugar canes grow after receiving 16 random ticks. However, when the wiki converts this to an 18 minute average time for one plant to grow to 3 tall, it is using the Java random tick speed. Bedrock defaults to 1/3 of that rate, so a single sugar cane plant will average almost an hour to grow to full height. Or 30 minutes for 1 stage as @unknown reported above.

The above screenshot, Windows PC Bedrock v 1.17.0.56 Beta, was produced after standing near the sugarcane for 3 real hours. I think the tick is no longer toking after the v1.17.0.52 Beta. The change affected the nether portals too.

Skaijie 2021-05-16T02:42:05Z

Sugar cane still grows for me on Android, which I checked by setting the randomtickspeed gamerule to 100. Is your randomtickspeed set to 0? By default it should be 1.

Bubba Doodah 2021-05-16T03:09:08Z

@Skaijie, I posted screenshot of my Random Tick Speed, see above.

GoldenHelmet 2022-06-15T00:31:58Z

I created a test world for this bug,

[media]

. This world consists of a semi-automatic sugarcane farm with 500 plants. To use the world

Flip the lever to set random tick speed to 1.
Wait between 20 and 40 minutes.
Press the button at the top to dispense water, wait a few seconds, then press it again to stop the water.
Check that all of the sugar cane makes it to the bottom and wait for it to be moved into the chest.

Expected result

After 20 minutes nearly all of the sugarcane grows to full height, so you end up with close to 1500 in the chest. That would match what was reported on the wiki, about 9 minutes on average for a plant to grow once.

Observed result

Bedrock: After a 36-minute trial I collected 1279 sugarcane.
That's 36 minutes / ( 779 growths / 500 plants ) = about 24 minutes for a plant to grow once.
Java: After a 20-minute trial I collected 821 sugarcane. (After discovering that water does not break sugarcane in Java I harvested it using a /fill...destroy command)
Thats 20 mintues / ( 321 growths / 500 plants ) = about 31 minutes for a plant to grow once!

So my conclusion is that there really is no disparity here, and thus no bug. Either Java has been nerfed for parity or the wiki was wrong all along. And perhaps the fix to MCPE-145612 help to equalize things or tipped the advantage to Bedrock.
