Algae tank

Production Viking farm

A small support building that earns its place thanks to the low price and quick build, even though its benefit is indirect through field productivity.

What it's for

Plant debris is made into algae in the algae tank. Algae increase the production of the winter fields you use them on.

The kelp tank turns plant remains into kelp, which boosts the productivity of the winter fields on the Viking farm. It's a smaller and cheaper processing building (6x5) with low worker requirements, from 3 up to 9, so you can put it up and upgrade it soon after you start. It suits players who want to get more out of the Viking fields than they give untreated.

When to build it

Build it early, because it's cheap (30 thousand to get started) and takes only 20 minutes, so it won't hold you back while your farm is getting going. It pays to have it finished before you start working the winter fields harder and want to squeeze more out of them. One is enough.

Is it worth upgrading

The interesting thing about this building is that upgrading doesn't raise the amount of kelp you get from a single batch of 240 plant remains – it's still one batch of kelp. What changes is the time, dropping from 4 hours at level one to 1 hour at the top level, so upgrading mainly pays off for how often you can top the fields up with kelp.

Tip from a veteran player Since the amount of kelp per batch doesn't change with upgrades, the thing to watch is your supply of plant remains – that's the real bottleneck here, not the capacity of the tank itself.

Most common mistake Players often underrate this building because it doesn't make anything you can sell directly, and they leave it standing unused – yet without kelp the winter fields don't yield anywhere near what they could.
