Hello! I have put my 7 day old auto cbd cheese seedlings into my 25x36x57 tent with a 1000LED as there is no sun outside today. How far is a safe distance away from the light for such younglings? They will eventually be a tent grow under 1200 watt LED in a 3x3x72

Yeah, what the others said. Tho, I'd say a couple of minutes rather than a single one, just to be sure. Heat builds up slowly if it's not instantly burning.. I don't know how much heat your 1000w lets out, but my 300w starts damaging the plant at around 10 cm, so I keep it at minimum 20cm away. So your 1000w probably shouldn't get closer than 30cm, while 40 - 45 is probably better. - Though, measuring the heat with your hand will get you a better idea.. Just test it out at different levels and fins out what suits you. ^_^

I would put it to where the back of your hand is comfortable under the light for a minute. Meaning no strong light heat hitting your hand. Cheers friend
