I have been playing since it came out and never have came across the teir 4 seeds, can you only get them by buying them in the store? ever since i got the highest upgrade in soil and all i have only seen tier 3 seeds and i am going crazy, it has been 4 days now and nothing but the same old plants!!!i am just now starting to get tier 4 flowers on my plants too!!!

You need to use something else you can buy from the shop to help generate the tier 4 seeds.

Ahhh...the elusive tier 4 seeds. Alas, they went extinct years ago and cannot be found through crossbreeding the seeds of today.

mutation liquid?

To get the tier 4 seeds, you can use the mutation liquid.

or buy the extinct seeds.

thanks everyone!!i finally got my first one!!!!! only took 4 bottles of mutation liquid on 1 plant.

I got them by buying them in extinct seeds.
