400 Watt Parabolic Distance

What's goin on RIU,

I got some sprouts that are about a 10 days old and around 2.5 inches each. I've read that I should keep my type of light around 1-2 ft but I've never seen anyone with a parabolic reflector ask yet. Is 1-2 ft really safe to be that close with a bare bulb like that? I have one of those Honeywell fans blowing air directly at it to make sure the temps don't get hot above the plants.

Use a thermometer at the plant tops. Or the back of your hand. If it feels comfortable under the light after about a minute your plants should be ok. It's a good place to start, anyway. Distance is relative to your growing environment to a degree.

I have a thermometer in the room and its around 78-80 in there with lights on and 72-74 with lights off.

If that's at plant level that should be fine.

Well that's not at plant level, that's just the closet it's in. I have a fan blowing at plant level so I'd assume itd be slightly cooler than those temps.

You're golden then. GL w/ the grow!
