OMG.... That thing is HUGE...and it has eyes....

I would like to add a few things if you don't mind....
First of all make sure, that it's not gonna overheat...i see you have a proc. cooling fan, but make sure that there is enough air movement, or the plants gonna get fried....or worse....
It would be wise to add another cooling fan, if one stops for some reason, there is another that keeps on moving....
Make sure that there are no blank wires, etc....
And you need to make it lightproof....if the plants get light during the dark period, they gonna get fucked up....
And please be VERY careful....
