Okay
@Grimz you'll need these to start your journey off with zeo and keep it running but here's the process for the 14 day cycle written by KZ:

You'll need the following to run the basic zeo system, the rest comes later once zeo has settled and you start to tweak colours:
ZEOlite (the stones)
Carbon (I use zeo and you may as well too if we're buying there)
ZEObak
ZEOstart
You don't have to worry about food as that's a nutrient import and is only required much later on down the track! It's pretty much up to you have much of each you buy though, check out the ZEOvit guide and work out what you'll need and then buy accordingly! The stuff lasts a fair while!
