I've updated the server to the 2.1.6 version of FTB Magic Farm 2. You have to choose the 2.1.6 version from a dropdown in the launcher to play it. If you leave it set for "Recommended" then it may start up a different version and you won't be able to connect to this server.

I'll say now: No, you can't start your tree with a giant sacred springs oak or giant redwood; and bamboo is not a tree. Stick with real trees that have a 2x2 trunk or smaller.

There are a couple of mods disabled by reasonable request. You'll need to disable them in your pack as well.
Using the [Edit Modpack] button in the launcher, you'll need to disable the mods listed as disabled in the changelog.

It'll also be necessary to replace your microblocks.cfg with the one in this zipped folder or paste the following over the contents of your microblocks.cfg:

I'd also recommend enabling Journeymap, at least to start with, so that your client will map the server when you are looking around for your tree. You can see your map (while you have minecraft running) by opening an internet browser and typing "http://localhost:8080" or by just clicking on that address here or by pressing j in-game.
It may be too intense for weaker computers, though.

I'll probably make a few config changes as we go. I'll post them here when they happen so you'll know what I'm doing.
