Talk:Tutorials/Mushroom farming

I created the page but I'm not too experienced with wikis so I'm relying on everyone else to flesh it out for me... I Make Things 08:23, 29 May 2011 (UTC)

Update to The Simple Methods
I believe that the simple method descriptions should be updated to include a strategy that I have used for my simple farming setups. Rather than keeping the whole farm 1-block high and then having to dig/alter it to get to all the mushrooms, it should be suggested to instead use glass as a floor block. Glass prevents spawning and allows for 2+ block high walkways for access to the whole farm. This makes a pitch-black, mob-proof, permanent mushroom farm possible that requires no upkeep or on-going modification. Mikedoyal 20:11, 27 June 2011 (UTC)

My current farm is netherack paved (in normal realm) and doesn't seem to spawn mobs while pitch black and a 2 high cavity. This takes a little setting up (excavate, gather netherack, lay netherack) but is probably the easiest to harvest for a simple design Fists 06:34, 8 July 2011 (UTC) Scratch that, creepers Fists 07:07, 8 July 2011 (UTC)

Technique Discussion
I haven't tried anything fancy yet, usually its just a dim cave thing that I put my mushrooms in. I was thinking though, having, say, 1 block with a mushroom on it that is surrounded by a light level of 12 on all sides could allow you to make an automatic farm, where a mushroom spreads to a nearby block and is quickly popped up by the light into water currents or something. I Make Things 08:26, 29 May 2011 (UTC)

...that would work, but since mushroom farming is so slow, it would be hard for it to work effectively... I think using that on a much larger scale, where you use either 4 or 9 mushrooms, surrounded by fire covered in glass to create a 12 nd 13-light area around it, while preventing the mushrooms from getting burned... ...the only problem would be collection, and that's why I posted below ---Dark Pulse 01:11, 6 June 2011 (UTC)

Harvesting Possibilities
there are a few possible harvesting methods I'd like to explore, and I'm not sure if they work or not, if known, please comment:

1. Sand - Do mushrooms hold the same property of holding up sand that torches do? if so, perhaps slowly layering mushrooms could be a harvesting method (but it appears mushrooms can't climb 2 layers (IE, grow on the block directly above them) - and if they do, will they "pop out" on a large collapse? 2. Water - what's a mushrooms interaction with water? will the mushrooms pop out if hit by water? this would mean a method simmilar to sugar cane farming would be very easy. 3. any other harvesting possibilities??? --Dark Pulse 01:04, 6 June 2011 (UTC)

Red and Brown comparison
I started my own farm with something like 3 red mushrooms. I found about 4 brown mushrooms a good few days later. Only one red mushroom has grown in all of their time, but the brown mushrooms have been spreading like mad, with 3 or 4 new ones popping up. I Make Things 08:29, 29 May 2011 (UTC)

I'm not sure and haven't tried it but i'm going to make a room with one glass wall to look through and a door on one side have a hatch in the roof, which is three blocks from the ground, and have a torch behind it and have one of those every four or so blocks because that will, most likely, give the room enough light to grow the shrooms and not allow mobs to spawn.--Ormidda 08:49, 31 May 2011 (UTC)

sorry put it in wrong one it is supposed to be in tequnique. --Ormidda 08:51, 31 May 2011 (UTC)

(This is SMP) It seems to me that Red Mushrooms grow much slower than brown ones, though I may just be being unlucky. Nbord 22:58, 31 May 2011 (UTC)

(ssp) i have one room with even numbers of red and brown mushrooms, lit by redstone torches, and in there the growth rate is fairly similar but in another larger room i planted one red and one brown mushroom and left it completely dark. when i came back there were about a hundred brown mushrroms but the one red one hadnt spread at all in total darkness.

My Own Analysis
I've left Minecraft running on both SSP and SMP, observed both planted and natural/generated mushroom fields growth. I made a slight effort to do controls, but mushrooms are tolerant to everything but bright light. I set up a mushroom farm and left it running for 6 hours, and went from this, to this, to this, and the mushrooms passed through the wall to outside the farm. (Note, my texture pack is "Visibility", blue/purple mushrooms are red mushrooms, green mushrooms are brown mushrooms)

My initial conclusions (which may be proven incorrect) about mushroom growth are:
 * Mushrooms can spread, in order of preference/likelihood, 1 square either diagonally or orthogonally, 2 squares orthogonally, up a layer via an adjacent step/block, and rarely down a layer via an adjacent step/block (if at all).
 * The 2 square orthogonal growth ignores 1 block wide walls, meaning mushrooms can expand beyond the walls of the mushroom farm (as indicated by the 3rd screenshot above). Does this mean mushrooms exhibit the ability of quantum tunneling?
 * Brown mushrooms seem to grow faster than red mushrooms.
 * Growth rate may be affected by light, and this may contribute to brown mushrooms' faster growth rate, at least in complete darkness, since they emit level 1 light. Both mushrooms seems to grow slightly less in darkness, but I am not positive.
 * Proximity to water and the material the mushroom is planted on has no discernible effect on growth rate.
 * Mushrooms will not spread to a tile with a light level greater then 12, understandable considering they cannot naturally spawn in light greater than 12.

I found that the best pattern is one that simply allows for the most lateral growth. Assembling the mushrooms in a grid pattern, 3 squares apart (2 empty squares in between, with each mushroom getting 8 empty squares to themselves). If space is limited, the mushrooms can be placed 2 squares apart, though more frequent harvesting is required (roughly 4 hours compared to 6, with my farm sizes of 8 each of both mushroom types). Alternatively, simply exploring the nether and then idling in the nether will eventually cause literal fields of mushrooms (this is near the entry to the nether on the SMP server I frequent, after about a day of the nether being activated on the server: http://oi51.tinypic.com/24kxj4z.jpg apologies for the darkness, the texture pack should make things easier to see. A day later, the size of the brown mushroom field about doubled) AndroidAR 15:12, 30 May 2011 (UTC)

I think that brown mushrooms spread faster in complete darkness, but red ones faster in light levels above 8. I had a room in 0 light with 2 brown mushrooms and approx. 100 blocks of space, and came back 2 hours later, and there was 5 mushrooms. My dimly lit (7-10 light) semi-auto farm had more brown seeds than red, but the reds spread only slightly slower. Stripminer123 09:35, 9 July 2011 (UTC)

Comments by CrispyLiquids: I have a mushroom farm on an SMP server, it's 18x18 blocks and contains an equal amount of brown and red mushrooms. Though I am not a registered user on this wiki (I logged in with BugMeNot), I thought I should share my findings on this topic, as my farm is doing great. The layout I'm using divides the brown and red mushrooms diagonally, with the diagonal line having no mushrooms planted on them. I started out by leaving an empty block in between two mushrooms every time, and leaving an empty line between two rows of mushrooms. Note that this farm is in complete darkness, there are no torches whatsoever and the room height is 2 blocks, underground. Being on SMP, I didn't not measure the time it took, but it quickly grew and completely filled the farm with mushrooms (against expectations). I noticed, time after time, that the Red Mushrooms (not the Brown ones, as mentioned in AndroirAR's experiment) outnumbered the Brown ones; meaning they grew quicker in these conditions (Would total darkness benefit Red Mushroom growth, whereas non-total darkness benefit Brown Mushroom growth?).

As for the most efficient mushroom farm, the method I just described is not the most efficient one when it comes to 'time to harvest' vs. harvest. I think the least time consuming and efficient way is to harvest compelete rows of mushrooms by simply holding your left mousebutton while walking in that row, like one would do with Sugar Canes (but not with Wheat, as you would crush the crops). Personally I harvest one row and leave the next one, and continue like that. The truely optimal setup will depend on how frequently you wish to harvest your mushrooms; after all the more time you leave in between harvests, the more space your mushrooms will need to spread further. As I was writing this text, which did not take too long, 11 Brown and 18 Red Mushrooms grew on my farm. Minecraft wiki 12:42, 5 June 2011 (UTC)

Should this be merged with mushrooms?
I don't think so because cacti and reeds got their own pages, and there is already a lot of discussion here that would clog up the mushroom discussion, not to mention the mushroom article being quite long enough already. I Make Things 09:52, 31 May 2011 (UTC)

However, this article is currently a stub, and needs drastic expansion to be considered a full article. A tutorial for a simple automatic mushroom farm would probably help many people.Thehiddenones 17:33, 31 May 2011 (UTC)

I think this page should remain. There's a lot of information to cover on this topic. Nbord 22:59, 31 May 2011 (UTC)


 * I vote keep this pageTheesexiestman 21:53, 2 June 2011 (UTC)
 * well enough time had passed and most you all want it to stay...what ever, I'll take down my request.--Yurisho 21:59, 2 June 2011 (UTC)

Which blocks do mushrooms spread to?
Title. This can be added to the main article. I know right now they spread on: Nbord 23:01, 31 May 2011 (UTC)
 * 1) Dirt
 * 2) Grass
 * 3) Sand
 * 4) Stone
 * 5) Cobblestone
 * 6) Chests
 * 7) Furnaces

They just spread to any opaque, solid block. C ali nou - talk × contribs » 23:08, 31 May 2011 (UTC)

Ah, okay. I'd still like to see this tested, though. Thanks! Nbord 23:10, 31 May 2011 (UTC)

Time to update?
It seems like a few things can be agreed upon: -Stuff Mushrooms grow on -Brown grows faster than red (About 2x as fast, in my experience) -The only major factor on growth is light - common sense

I think it's time that we added some of that stuff to the stub. Snails 06:00, 7 June 2011 (UTC)

Spread Mechanics
I've updated the main page with a description of how mushrooms spread. Here is the more concise, technical version:


 * firstChosen.x = mushroom.x + rand[-1, 0, +1]
 * firstChosen.y = mushroom.y + rand[-1, 0, 0, +1]
 * firstChosen.z = mushroom.z + rand[-1, 0, +1]


 * secondChosen.x = firstChosen.x + rand[-1, 0, +1]
 * secondChosen.y = firstChosen.y
 * secondChosen.z = firstChosen.z + rand[-1, 0, +1]

It's not easy to visualize the "spread map" in one's head. (Well, my head, anyway.) It's symmetrical and obviously prefers the immediate neighboring blocks, but that's about all I can deduce without writing a simulator or reverting to using pen, paper and probability (*shudder*).

I'm not sure it's worth the trouble; I'd just build a "flat" farm, but it may be interesting to figure out the optimal seed pattern.

I'm not sure if the spread mechanics are correct.

1 tick = 1/20 seconds 100 ticks(how often on average a mushroom will try to spread) = 5 seconds

take a mushroom planted on level ground with an open 5x5 square around it

50% chance middle 3x3 will be chosen 8/9 chance the first block will be open 8/9 chance second block will be open

5/0.5/(8/9)/(8/9) = ~12.66 seconds

I certainly have never seen mushrooms grow that fast. I was thinking maybe there is just less chance per tick to spread? Any ideas?

Light
Is there any method to know, do the different light levels affect on the mushroom spread speed, by opening some game files or viewing game code? I mean, is the exact answer to this question? --R0B 18:43, 7 June 2011 (UTC)

You can decompile the code and and look at BlockMushroom.java yourself. The only thing needed, in regard to light, is a light level less than 13. Mushrooms do NOT grow slower for every light level above 1. The front page is wrong. --Darkhand 11:58, 18 July 2011 (UTC)
