With movers you need to increase the air flow. The reason you noticed a bit warmer temps is the light is warming a larger area and when it moves from point A to point B then point A cools down a bit and visa versa.

That equals a bit warmer and un-even temperature (but really a more accurate temp of the whole grow area if you think about it)
Zandor Reviewed by Zandor on . 600 Watter with mover. Here are some more pics of the progress. Just started flowering and they have taken off! Nuttin' like lumen power. I have noticed a variation in temps with the mover,though.I can keep the temps stable with the tempstat.I'll keep posting the progress all the way to harvest. Ga Grown! Rating: 5
