I spoke for ages with james Findlay, green machine about the set up and he said if he's setting up a tank in the shop without the constraints of being filmed he always runs for 3 weeks before planting. The ammonia released from Ada substrate does the fish less cycle but he said to run in for three weeks. 70% water change a week and plant on week 3. Also gives you time to fine tune hard scape etc and avoid any algae blooms. I'll end up spending over £100 easily on plants and he said if I do it this way I should have no losses whereas plant immediately using Ada substrate and I'll lose a fair proportion due to the ammonia / potential algae etc.
I'm in no rush so will follow this method. The tank layout will be similar to crimson Skye seen in his journals so I'm not one to argue if that's how his turned out!
