Ah I see, Well I have some alternatives for you, There is "Any planet start" which actually starts you on Gleba, with minor tech tree re-arrangements to make it possible. Which is how I had been doing my own starts, which may interest you as a valid alternative. Although Its more similar to the base game in that you can go to other planets etc.
Something I have been considering is removing the crafting pressure requirements for all cultivators - as they are also running into problems with my Vulcanus demolisher farming mod haha, where its very time critically difficult to get the ingredients back to Gleba to do the craft lol.
I will likely make this update when I next get a chance to work on the mod - as I have some other minor bug fixes for some other mod compatibility to make too. You should find it very easy however to simply delete the lines that requires surface pressure in the recipe / building within my mod as a work-around too in the lieu whilst I find the time to catch up on this haha.
For any compatbility issues with Quality Seeds, come to me as this works at the final data step, but my other mods should hopefully be introduced early enough in the pipeline that issues with tree spawns etc is more the roll of the Gleba Only mod creators to deal with, just as an fyi =)
