Is zombie farm sustainable?

[Idunnnnn]

Using only the zombie farm will you always have enough seeds?

I built a level 3 some time ago and only used it once to experiment as it seemed to need no fertilizer which is pretty cool

But I was worried about the seeds.
Does using the zombie farm have the same chances of returning seeds if harvested manually? Or no seed comes out?

I am currently using quality fertilizer 2 (silver star) and planting by hand and it is being sufficient to maintain seeds.

Does zombie efficiency affect the amount of seeds / crop?

If the answer is yes
Does anyone have an optimized layout?
I like to reserve space for other types of plants if possible.

Thanks

Short answer; in my opinion, *yes*, with a lvl 3 farm and a 16W (40%) zombie, all-be-it based on my own experience while others have disagreed, making it fairly difficult to know for sure.

Long answer; You have potentially two known variables - the level of the farm, and the efficiency of the zombie operating it. One may also need to consider things like the Farmer perk, along with the random chance that is present throughout many aspects of this game, including farming.

The farm's level simply determines the produce yield (going from 32/20 to 36/24 to 40/28), along with unlocking higher-quality-veg. However, there certainly could be other hidden variables, such as the rate of seed production, but it would take a LOT of trial-and-error to come close to figuring this out for certain, which I doubt anyone has bothered to test extensively. At the very least, zombie farms do receive at least some seeds back from their operation.

A zombie's efficiency is just as mysterious; they certainly seem to perform their work faster, though it's near impossible to prove that the quality of their work increases, or - in this specific case - if they return more seeds. Having said this, when my farming zombies were <30%, I needed to supplement their seed production, while after I eventually got around to upgrading them to 40%, I haven't since - I actually think it's been net positive.

Layout: It's mostly personal preference. You could build as many as 6, but I find 3 to be more than enough - 2 running gold-veg 24/7 for the Merchant, and the third doing anything else you might need (carrots, wheat, etc. - or lentils, so you then won't have to worry about garden-bed-with-sticks). The one crop these farms can't produce is hemp, so I'd dedicate a 3x4 section towards that until you're confident you have enough.

Thank you for the answear ^^ Help alot!!

If you have a maxed leveled farm and three of them. You will basically run a perfect match for the merchant if all zombies are 30%. Remember you can not produce more then 10 crates a week without overflowing.
