I am currently running two 4*4*4 multiblock farm underground with my cross bred tree. Since I do not have a Balsa tree on hand my best choice is breed a Oak+Cherry, which gives me the trait of "fastest maturity", "small in height", "highest sappiness" and "normal yield".

I then run them on two fermenter and two squeezer with full automation (energy tesseract, item tesseract for input/output). The problem I encounter now is:

1) I have WAY more apple than I need to. I am sitting at 14k apple in hand and the number just keep increasing. I just use apple juice and mulch for my fermenter but they just cannot keep up, see point 2.

2) The sapling just cannot catch up for even one fermenter usage. Maybe oak tree sapling yields is just too low for fermenter.

3) It still burns through dirt like crazy (not so much for fertilizer). Though I am going to get maybe 4x peat farm.
Re 2, if what you mean is that the fermenter is not working all the time, than I agree, it's not. It's more than enough to produce biofuel, though.

Re 1, the problem with apple juice is that the squeezer is just to slow to keep up with the fermenter. It's fine if I plop a few stacks in the squeezer and have it supply apple juice to the fermenter. But if it's just squeezing what comes in, the lack of apple juice becomes the hold up. Right now, I just switch to water when that happens, then switch to apple juice when the squeezer gets full of apples. It's WAY slower than the fermenter, so I don't even think two squeezer will be able to keep up, though I didn't test it.

I see, I think I misunderstood your point back then.

I actually had an interesting design before I made my new tree farm. I connect squeezer and aqueous accumulator to the same liquiduct system to fermenter. I set "Liquid in tank, red pipe signal" on squeezer and connect to AA setting "red pipe signal, redstone signal". This will in fact output apple juice whenever there is idle juice inside.

I am using a 2 squeezer and 2 fermenter ratio as my sapling is unable to keep up with the speed I get my apple. But my friend gave me like 60k sapling yesterday and I find squeezer is what holding it back (not so much). After some testing, 2 squeezer full running is able to keep 1 fermenter uptime at near 100%

Can you post a pic of that ultradolp? I'm having a hard time wrapping my head around what you wrote regarding the liquiduct connection. It sounds like what I tried, but there must be something I'm missing since it didn't work for me.

Hmm I think all farms request 75 mj/t when they need energy but they actually are very energy efficient compared to the old farms.
Orchards/Infernal Farms/Arboretums will only use energy when they need to do something(simply plop down an energy cell and you'll see it doesn't use any energy if it doesn't have anything to do).
The other farms too probably but I haven't played with them so I can't say for sure :p.

Just to make it clear because I just had this exact conversation with someone: Many machines have a peak consumption and a consumption per unit work, I think. So like, a big multifarm isn't going to permanently draw 75mj/t. My test farm certainly isn't. So it can take a lot less. But if you buffer with an REC it'll pull quite a bit to keep its own internal buffer full. Like many MJ machines, I think it'll just operate more slowly when supplied with lower power sums.

Yeah, it's beggining to become a thing with MJ machines, to increase in speed as energy available increases, which is always nice. No messing around with overclockers is fine by me.

I can confirm that the farm can draw quite a bit of energy when there is task to do (planting soil and harvesting). Keep in mind that it is only a spike usage not a constant one. So instead of using an engine powering it 24/7 the best way to do is put a redstone energy cell in between to buffer the energy. The buffer allows you to not waste any energy output from your engine as well as providing insane speed when needed

Here it is, the setup is very easy and has many flexibility to fully automate the whole process. I have one that automate the multiblock farm input/output to charcoal production and biofuel to keep my boiler up and running

Thank you! <3
I did two things wrong, lol. 1) I failed at actually having a successful redstone signal on the AA. I thought my jacketed wire would give it a signal. Nope, only transferred it to the block next to it. Structure pipe and redstone wire work much better. 2) had the AA on high signal, not low.

>.<

Awesome. I'll try to get that working. I ended up moving my apples to the void because I couldn't figure it out.

lol i just kept making more and more barrels to store stuff them in... i'm a cheapskate :p plus i have tons of wood still. should have enough steel for another boiler by tonight and if my friend really does have as much as he said to trade, i can maybe make 3 more steam turbines to use all that steam for my matter fab with some steam left over to energy cells to use in the laser room. now if only i had more redstone to fill them with.

It's now been running for a week. My iron tank got up to around 2800 tanks of biofuel, before I lent some to another guy on the server to setup his own boiler (he just needed to get to 1000 degrees and is now running on his own). But now my iron tank is officially full at 3200 buckets. (Unfortunately, I didn't give myself room to expand the tank to the full 7x7x8 size).

Of course, everything is backing up now because there's no place for the biofuel to go now. I'm probably just going to shut off the multifarm for now and just let the boiler go through the 3200 buckets. Because the full-sized HP boiler uses 36 buckets per hour, this will last me 3.5 days before I run out of biofuel. So I guess I will just shut off the multifarm until sometime on Tuesday. Saves me the trouble of having to start quarries just to get dirt. Thing is, with the multifarm off, I really don't even need MJs. Right now, I only need MJs for the multifarm and for the quarry. But I'm only running a quarry for dirt for the multifarm.

I'm contemplating setting up another boiler, but this one as solid fueled. Basically just to see if I can. I've already calculated that it is theoretically possible (actually, it's theoretically possible to run 2 solid fueled boilers and 2 liquid fueled boilers from a single max size multifarm), but I just want to see if the sawmill and pipes can keep up. It "only" needs 2.4 gold chests to get to 1000 degrees, then 10 stacks of wood per hour. I saved up 5 gold chests of wood before I finally got tired of it and decided to send all new wood production to the void.

Got my second boiler running, this one off of the wood. It's a little annoying. The liquid one took some research to do, but once it's set, you forget it, because the iron tank fills up and the boiler takes only what it needs. With the solid fuel boiler, the extra wood just gets thrown onto the floor. I just ended up setting up the pipes to throw half the wood into the void. I think it should be working fine now.

Use something that won't drop items to push the fuel. One popular option is a tesseract fed by RP2 components. An evolved (and slick) way to do this is to use a router that uses a machine filter to target wood into sawmills. The sawmills eject into the boiler automatically. Then you just need to void the sawdust (another router can do this).

Another option is to use an AE exporter for planks (or use an AE exporter for wood into a sawmill that ejects planks).

What are these Multifarms you speak of? I'm playing with hardcore RP2 Deployer/Block Breaker/Frame farms!

Yeah, I have to do something. Half the wood is too much--the boiler goes below 1000 degrees. I was thinking about some kind of router/timer setup. I don't have dark iron yet, but I suppose I can get some. In the meantime, I'll just put a golem there to pick up the dropped wood.

Boilers pull from chests that sit next to them. Just pipe into a chest and it will take what it needs.

if you have liquid storage problems and the area where you build things is a bit crowded, take a look at the quantum tank. it stores 2 million buckets in just a single block. but it's quite expensive and requires a lot of gt-infrastructure (like an ind. blast furnace with more than 1700 heat, and a way to get platinum or shiny ingots... and I'm not sure, if it even requires iridium plates, which are truly expensive).

The Forestry mod used to have the arboretum and logger for tree farms and the farm and combine for wheat farms.

With version 2.0, they have made those obsolete and added a new farm--the multifarm. It's called "multi" because you can plant different items in it. It's divided into 4 quadrants and you can even plant different things in each quadrant. For trees, it automatically plants saplings, harvests the trees and re-plants new saplings. The only things you need to give it for maintenance are power, fertilizer, water (from an aqueous accumulator), and dirt (when a tree grows, it replaces the dirt with sand. (You obviously have to give it saplings to start with, but once the tree is harvested, it harvests the saplings, replants some, and outputs the extra). Here's the official page for multifarms: http://forestry.sengir.net/wiki.new/doku.php?id=farms:multi

For purposes of this thread, I'm using the largest multifarm (5x5) as a power source. I originally built it because I needed some trees. But it harvested so quickly, I thought I could put it to good use. So the saplings, I turn into biomass via fermenter, then into biofuel via stills, which I feed into a liquid-fueled boiler. I turn the wood into wood planks via a sawmill, then into fuel for the solid-fueled boiler.

This is what my multifarm looked like this morning. I ran out of dirt over night, so everything is just sand. It goes through a ton of dirt. I completely filled a barrel and an enderchest with dirt on Sunday morning and it ran out sometime overnight.

Once you put dirt back in the system, it replants the saplings and trees start growing, like this:
