Ok, just went the Minechem route to make naq and other stuff for the stargate. It is assembled, and seems to be working, I just need to run power to it. Next time I get to play I'll fire it up and go get a tardis. I got to tell you, the grind is real. I had an upgraded barrel with almost 300 stacks of coal. Emphasis on 'had'. I also had barrels with about 200 stacks of lead and chlorine each. Those are not quite empty, but very close. Making 64 ender pearls is quite a bit of work, as is making something like 3 stacks of Naq ore. At one point today I used 20 or so stacks of diamonds for..... god, I don't remember. Its been like a 10 hour day doing this today. I've done all the quests except getting the tardis key, and the one for the level 6 solar panel. Eventually I'll grind out stars until I get 8 of the same kind and see if I can make a level 6.
I have to say, my base is butt ugly, but it works. The ground level is pretty big, has a tree and other farm on it and is entirely enclosed in blast proof glass that is illuminated. I have a star farm on top of that and under ground I have my main industrial plant and under that my power area. At some point I'll probably tear everything down and layout it nicer and make it look like something other than a hole in the ground. Maybe if I'm feeling adventurous I'll do a world tour video this weekend. If anyone is really bored, my profile here has a link to my youtube channel with 1 video of my Regrowth world.
Good luck everyone.
