Selecting equipment for first grow

So i can finally grow and am selecting all the stuff i need to grow, this is what i have in mind so far.

Large Budbox - 100X100X200 = £100
600W ballast + diamond reflector + Sodium & Halide Lamp Combo = £165
Easy rollers = £5
RUCK fan 125A - 295m3/hour + carbon filter + ducting & clips = £110
Light controller = £24
Plagron light mix soil 50L = £13
Hesi soil 5 litre package = £92
Square Pot 1.7 Litre - 12cm x 13cm. Box of 25 = £6.50
Square Pot 11 litre - 26cm square by 27cm high = 1.35 each

Total around = £517

What do you think?

I was hoping to get 9 plants in there but would there be enough room as it would allow about 33cm square for each plant? Would the 600w light be enough for the 9 plants too? Im going to get a small desk fan to blow some air in and then some little clip on fans to blow the air around a bit.

Im going to research more into the nutes and maybe the soil more because i think i would prefer to grow organic. Any suggestions would be really helpful. I hope to order everything this week and then do a grow journal once i start.

Thanks for the help.
