Metal Halides to reach the depth cause they're more powerful...? But they are also more expensive and hotter right?
Would 4 x 39w T5s be sufficient?
I don't think I need super bright, but don't want to go to all this time trouble and expense, only to fall short on lighting... The LFS
guy suggests the above, (4 x 39w T5) but I've learned to question what I'm told by those guys...
And would I need a cooling fan
Sorry, lots of questions.
