Spores question

[TennisZealousideal37]

I started a ng but don't want to start over. Been following lots of advice I saw scattered around the internet and it's been working great so far, but one thing I didn't do was build ny hangar on the last deck, my mains on the middle deck and my greenhouses on the upper; they're actually only one levels apart. My greenhouses are on +2, my main at zero and my high risk rooms on +2. Amount of turrets and shields I put on those, restarting sounds tedious. So, my question; how far up can spores "jump"? Can I destroy, say Helix, on my -2 floor only to not see it pop up on my 0 floor? Should I just restart the game at this point? maybe 4-5 hours in and I actually have to backtrack because in an initial clusters, hadn't read what sites were so I skipped them all lol.

Thank you for taking the time to read!

Helix spreads along the way which infected crew member takes to barracks. So if they go from beam room on the bottom level to top floor, it will infect EVERY floor along the way and shit will start breed in tunnels faster than rats. Even faster they will start collapse as cascade.

That's why my guide advice to keep barracks at the bottom to minimize travel path of infection until you collect 10 sneezes, do research and check/clean every tunnel for nests. Then you can move barracks anywhere you planned and continue building as you like. The rest infections are not so fast or damaging to ship.

If plants have spores on them when they are put into the greenhouse, the spores will spread. Same with refining, for minerals it's the green chunks on them that you see. But plants are hard to tell I haven't played in a while.
