Cheers fer the info mega & berrys. I love the way everyone is so helpful on here....i guess we are all in the same boat eh?!

I think i will opt for a 'Ecolite' 400w rising sun. I have both bulbs so i may as well use them and my understanding is they are switchable between the two.

I think i will keep the ballast in a sep room to keep heat down.

Now i need to sort out ventilation. How good are these carbon scrubber things?
Cheeeeeers
