No problem to hijack the thread
To say its just about Co2 and flow, is a bit "strong", since light is one of the most essential things for all living plants/animals. Aiming to get a balance between all factors.
The reasons I want 4 tubes, is to get the midblast, to give a proper day cycle.
As I said before, its only going to be 4 lights on for 2 hours per day.
My last hightech tank, a 375 liter one, was succesfully started with over 1W/liter and never had any problems with it really
Also want to get the spread, you mentioned Ady.
The best swedish plant site,
http://www.plantswap.se have some interesting Co2 consumption charts, which shows amount of light, Co2 and a lot more.
It can be found here:

Will try to get a journal started soon, have 5 days off work now, and plan to properly set up my tank. Got my Co2 set from Germany yesterday
Unfortunally, one of the biggest and "best?" suppliers of plants, did let me down, and did not send plants that i hoped for, even if I got confirmation that they were in stock before ordering, so might have to take a trip to London tomorrow or more local shop.
