Have you tried Buy in the USA, ship to Canada with BorderlinxI would start with everything on "full" but dim the entire light down a bit to start, 18" it should be able to run full out when your plant mass increases. It's set at 6500K which should look warmer than your light now. My 2.0 is 7500K and even it seem really yellowy. Good choice, I wish I lived in the states, the 2.0 is nearly $400 here and the 3.0 wont be available till "late 2018"... probably with a premium cost to it.
I got mine from Ken's Fish, I know there's services that ship from the USA to canada for low cost if any, I just read a post on it day before yesterday ill have to find it for you.
