strange everyone says this is the hardest one (because the gravity is changing) but i actually found all the seeds myself without any assistance from any other media on my second attempt on that garden and got all the spectra on the third attempt.
i guess i was just lucky.
my advice for that one is to just learn the map yourself. printed maps might be wrong, or misleading.
Also… that seed in the pic that “doesn't exist” DOES exist. it sprouts up into foliage.
