Lighting on seedlings

How close should my light be to my seedlings? I have a 400 watt mh light. I have it on 50% power

Folks on here told me 24 inches. I’m using a Mars 900 LED. I started at less than 6 inches and fried my seedling. After following the advice from the wonderful folks here I went to 24 inches and all was well.
Do you have them in a humidity dome?

I do and thanks I was thinking I had the light way to high and one is stretching way too much

I should include that after frying my seedling I went to 48 inches and this happened.


She stretched right out of the rooter! I sliced the rooter open and put her back inside then lowered the light to 24 inches.

your seedling never got solid roots. it pushed itself out of the media.
replanting n burying the root will give it a good start.

Oh yeah, she’s been replanted, vegged, flowered, dried, cured, and smoked since then.

First seedling going, not sure what it is, after reading in the forums I realized its stretching for light, I lowered the light this evening, using 4 T5 bulbs, how soon should I put a small fan in place?! This is 6 days from germination.

Yep slam that light down. You can also add some soil to the top of the cup to help support/bury it more.

Hey @Dman1969 I’m not to sure as I have only used the QB’s for lighting. Maybe @PharmerBob can answer that or @Missiles I’m sure would know who.
