I'm doing the Terrafinto challenge where you need to get Terraform everything at 100%. After about sol 120, I was at 100% Air, Temp, and Water while my vegetation was at roughly 30%. I've now covered the entire map with Forestation Plants, but after reaching 40%, they no longer increase the vegetation total. The only way I can see how to increase vegetation is to send a rocket to Seed Vegetation for 5% every 5-10 sols. Are there no other ways? I mean, I still have another 120 sols to get a perfect time, but that's so incredibly tedious. Or am I missing something?
