Light hight for seedlings


Got a question that’s been ask a million times but I can’t find the answer I’m looking for, I’m no rookie but I have always grown outside and start my seeds same way…but lmy his year I’m starting my seedling inside under a 600 watt Mars led and question is how much distance do I wanna be at? I’m at 30 inches now and plants are streching too much to suit me…any suggestions? Anyone?


I’m pretty sure @dbrn32 and @Countryboyjvd1971 can help you :blush:


@Sittingbull64 can you post a picture
If they are stretching too much lower your light to 24-28 inches and see how they react
I always start high and lower my fixtures until i find the sweet spot
I will start at 36 inches


I would say 22 to 25 inches. I keep mine at around30 for the first week then move it down as they gwt older and more size to them


That sounds like pretty solid info from @Countryboyjvd1971 and @Dieselgrower to me.


Sounds like good advice…I have it at 36 now so I will lower it…thanks all yall…like I said I’m new at using lights…always used the sun! Thanks @Countryboyjvd1971@smokngranny@dieselgrower@dbrn32 …


@Countryboyjvd1971…will post some pics in 24 hours after I adjust lights…


I always shoot for 24 to 26 in and watch for stretch if they start stretching I lower my light by 4 inches. I would rather get her to stop stretching then be worried about being to close once she stops stretching I may go up a cpl inches depending on distance but my seedlings usually end up 20 to 24 but my light is a 300 roleadro 2nd gen.


Looking forward to the pics. :slight_smile:


I am also new to indoor growing. I have a full spectrum 300watt LED light panel.

Because it is half the wattage of the 600watt the original poster mentioned should
I put the light lower above the seedling or the same height as you guys mentioned
above for the 600watt? :slight_smile:


I’m gonna go ahead and say this…I have always grown outside but like the inside too…I moved my light down as instructed but still had stretching so I have it at 20 inches right now and the girls love it! These most be a strong strain! But I would try 25 and go from there to find what they like


I would start it at 30" or as @Sittingbull64 said 25 wouldn’t be bad to try either and work your way down to find the sweet spot @OkieGirl. :v:
@Countryboyjvd1971 @Hogmaster what would you say?


I agree with you both I use the back of my hand to feel the heat
