I tend to make P1 products on my extraction planets. Then on my factory planet I take the P1 and make the higher level products.

Do not export P0, at least compress it into P1 first. Even if you are running through a low or null sec POCO with zero tax that is a lot of volume to move around each day. compression values on PI are fairly high.

Also the main reason for using factory planets is that you run multiple lines of the same product.

For each P3 factory you need to bring in 320 P1 of 4 different types. Basically to keep 1 P3 factory running it needs per hour to be feed by 4 P2 factories (10 of each P2) which in turn need to be feed by 2 different P1 factories each. So 8 P1 factories of 4 different types. If you import the P0 you need 12,000 units each of the 4 types or 48,000 units of P0 per hour. To only supply the factory planet once per day with enough mats to keep it running your planet would be half storage building from P0, P1 is much better for logistics, even though P0 may look better profit wise on paper.

Lets take your example of robotics. Say we want 3 P3 factories on the factory planet. you would then need 6 P2 factories producing Mechanical parts, and 6 P2 factories producing Consumer electronics. That and a couple launch pads for storage and you planet is pretty much full. To add the 24 P1 factories you would need to build from P0 you just do not have the space or the storage to maintain 3 P3 factories.

To feed that factory planet of 3 P3 factories you would need at least 4 extraction planets producing at least 240 P1 per hour. P1 factories produce 20 units per 30 minutes or 40 units per hour. So you need 6 P1 factories per planet and enough extractor heads out to pull in an average of at least 36,000 units of P0 per hour. This is just not going to happen unless you are deep in null or W-space. However even in high sec it is easy to run an extraction planet pulling about 20,000 P0 per hour and have enough CPU/PG to still run 3 P1 factories. So in high sec you would need 8 extraction to P1 planets to keep up with your factory planet. At least 9 planets total so you need to use two characters on your account to pull it off. Running a factory planet you also need to haul mats from your extraction planets top your factory planet at least once per day. this can really cut into your game time.

If attempting to do this on a single character you still have a few options left. You can set up 4 Extraction to P1 planets producing the two highest value P1 products you need, and buy the other two P1 mats off the market. But this can really cut into profits as many P3 and P4 mats are worth less than there component P1 and P2 mats. These are made more for compression purposes in W-space and deep null than to actually increase the mat value per hour. If you can make 20% more selling P2 then turning it into P3 then why make P3? Well logistics is the answer, material compression. Is that 20% increase in profits worth makes 5 times as many trips? if you are two jumps from Jita sure, but not if you are in W-space or deep null. One trip in a bockade runner per week compared to 5 trips at the cost of only 20% profits is well worth it for most players. When you have a long way to go to reach a market hub isk/m3 is much more important than isk/unit.

Thanks guys. u were rly helpful .

Any1 can share Extraction--->P1 prod setup?
Also can any1 share P1--->P3 prod setup?

i run a robotics production chain with 30 CCs on 6 null planets. all my extraction planets are P0 -> P1, run on 24 hour cycles and average 14-15 structures depending on size (1 ECU, 2 Launchpads and 10-11 BIFs). i have two factory planets making mechanical parts and two making consumer electronics, so four of the factory planets are P1 -> P2. finally i have one planet doing the robotics going from P2 -> P3. all my factory planets consist of 27 structures (2 Launchpads and 24 AIFs). even with all the extraction planets i have, i can only keep the robotics planet running solid 5 days a week; though i do have a few planets dedicated to other pos fuels.

I make a whole melange of things besides POS Fuel products so mine would not be very helpful for efficiency in that aspect.

I'll be definitely doing only P3s.
Thanks for the link!

For now i managed to setup my 4 extraction planets so each of them produces 2mil of P0 commodity/day.
Also skilling up for LVL5 CC upgrades and IC 5 so i can use 6 planets.

*P0->P3 production plantes will consist of:

12 BIUs producing P0-->P1
6 AIUs producing P1-->P2
3 AUIs producing P2-->P3

With 2 production planets doing this ill get 6 P3 AIUs producing robotics/character.
I have no idea how this setup will fare. Im looking for balance. So i want to extract just enough P0 to feed my production line without unnecessary P0 leftovers and enough of them so they will be able to feed my line constantly.

Any1 else tried this? Ofc any additional imput will be highly apreciated.

Besides hauling issues is there any other negative of my setup?

Doing it in Low Sec is the best idea, really. Use CovOps Blockade Runners for the hauling.

Also, you can cloak up in a system and, using the Overview, you can access the various Custom Offices and check which ones have the lower taxes before you do your setup. You can also transfer product to the POCO's from that remote location, making the actual pickup at the POCO's faster with less loitering while uncloaked.

Lucky you

I did explain this in post 4, but it takes 4 P2 factories to provide constant supply to 1 P3 factory. A P3 factory requires 10 units of each P2 product per hour. A P2 factory produces 5 units per hour. So to keep a P3 factory running you need 2 P2 factories for each input product, or 4 total P2 factories to feed 1 P3.

With your set up above your P3 factory will only run 50% of the time.

To run 3 P3 factories non stop you need 12 P2 factories, and 24 P1 factories. This is not possible on a single planet. Which is why you need to convert P0 to P1 on the extraction planets.

An extraction Planet in W-space should be able to run 6 P1 factories and still have enough PG/CPU to pull in the needed 36000 P0 to feed those 6 BIU's. 4 extraction planets each producing one of the needed P1 mats will supply the 12 P2 factories on your factory planet which will intern keep the 3 P3 factories running 24/7. This will put out over 200 units of P3 per day per factory planet.

The way I would set up an extraction planet in W-space would have 1-2 ECU's feeding at least 36,000/hr P0 into a storage silo which then feeds the 6 BIU's which output the P1 to the launch pad. This prevents congestion. You can feed the P0 to the launchpad and back out to the BIU's then back to the launch pad but if the launch pad fills before you get there to empty it out the extracted resources will be lost and the factories will stop. With such a volume being produced it will not take long for the launchpad to fill with P1. Having the P0 going to a separate storage silo ensures nothing will stop.

In W-space you should be able to pull in the needed 36,000 P0 with a single ECU with 8-10 heads out. I generally go slightly over what is needed to maintain a small buffer. This should leave you enough CPU/PG to support 6 BIU's a launchpad, and a storage silo.

Extraction planet
ECU(36,000 units/hr) >> Storage silo >> 6 x BIU's >> Launchpad

If you have trouble, running shorter extraction programs will increase the average output per hour, but will need to be restarted more often. I usually run 1 day 45 minute programs. This is the longest you can run on 15 minute cycles. When you hit 1 day 1 hour it jumps to 30 minute cycles. 2 days 2 hours it jumps to 1 hour cycles, etc. the longer your program the less P0 you will pull per hour.

A blockade runner can easily keep up with moving the P1 mats around. But if you insist on moving P0 mats you will be moving at least 7 times the volume per day. 6000 P0 at 0.01m3 is 60m3 while the P1 it would be converted into would only be 7.6m3(0.38 *20 units). rather than moving 4 loads of P1 per day you would be moving 32 loads of P0 to maintain the same thru put.
