Finalizing grow room... Some questions

Hey all,
So we're finally getting our medical card, so we can get our clones and get going. Finishing up the grow room, and I've got some questions.

1. So it gets pretty cold here come winter. We are installing an intake fan, but are concerned with that intake creating a cold spot in the room. We're considering having ducting go from intake along one side of the room, capping the end of the ducting, then punching holes in the ducting along it, so that the cold air is more evenly distributed across the room, so that there's not one spot getting this huge blast if cold air. Thoughts?

2. I have one 1000w dual-spectrum to make this entire 6-plant dwc grow work, start to harvest. Without too much on whether this is the right light (this is what I've got), how far from the plants should this light be for vegging? I've looked around and it's hard to find a definitive answer for a light that's probably more intense than necessary, especially when my babies are tiny.

Thanks for all the help guys

For 1, you didn't describe the "room". If yoy have exhaust, which I hope you do if you have intake, then I wouldn't bother. You will have air flow. Plus you want an oscillating fan on the plants in the room to make them strong.

Oh yeah, I'm definitely gonna have oscillating fans. So is there any benefit to having active intake? And yes, I have exhaust.

Also, any thoughts on question 2?

thanks.

cold air blasts, as long as they are over 60 f, because we have ac blowing into the room and they don't mind, and your light will work very well , great for a personal grow,

Once winter/late fall kicks in here, I'm talking below freezing temps.

Wont this also be an issue with passive intake?

And everyone, this is a 10x10x10' shed.
