Advice for young and long-stemmed seedlings?

he just means turn the light intensity down, so that when you bring your light closer to your seedlings to stop them from stretching it wont burn them
Yes I understood what he said but if you turn the light down but lower the light you are back where you started from. Why not leave the light intensity where it is and lowering the bulb a bit? I am thinking also if you do not have non-dimable lights. I just use regular led house lights for my tray.

I said I do not understand how reducing the light intensity from 10 to 5 by turning the light down then lowering the light to bring it back up to 10 changes things. If I disagreed I would have said "I disagreed..." rather than say, "I am unsure...".

I have seedlings a few days older than those right now and they stretched more than I want to see but they just popped out of the ground and shot up in a day. I lowered the light but the mature leaves started praying so I raised the light again.

And I didn't come here to argue the finer points of seedling growing with YOU , I answered a question the op asked. Period.

You can tell by the lips of the cup. That is why I did not think they were as tall as if they were regular sized cups. I would wait a while before sinking them lower in dirt yet fro the reason given. Just support the stems.
Ah everyone does it different. I'd totally put them deeper and bring the light closer. Might even be fine just putting in bigger pots which tends to bring up the tops of the plants. Also did anyone see anything about kind of light or how far?

if you can't understand that the plants are stretching because your light is to far away and it needs to be closer , even though everyone has told you thats the problem, then there's no point in even trying to point you in the right direction cause you already know everything..lol.its not about the light intensity its about the distance from the top of your seedling to your light. Geez. Not sure why you would even come on here to ask if your not going to listen to people who actually know what they are talking about.

He's not the op @JustBlazin

No, I realize that the light has to be closer to give the plant more photons. I just did not understand why you would turn down the intensity of the light as you do it. I thought it might be to reduce the heat of the light drying out the seedlings. This is legitimate if your light puts out an appreciable amount of heat. As you turn down your light output (leds) the light becomes more efficient (less heat for the amount of light it produces) but you put out less photons.

I am pretty good with technology, but new to growing (ok a year and a half of mistakes). I give advice when I can, I try not to when I am unsure and it makes me look like a quackpot. I save those moments for the Political section of the forum.

Actually thinking about it, I think the heat is the reason you would turn the control down and lower the light.

Id be more interested in what light the op is using/has? Obv, they need more light but what if he doesnt have near enough anyways to go any further.

No cfl bulbs, led bulbs, hell old incandescent? Anything will help when they are that young.

I had some long CLF fixtures with grow lights in them and laughed one day when I came down to see my young plants and the leaves were wrapped around the tube. Went Led soon after that.

Now come on...

I have seen dozens of posts or more with people intending to use far inadequate lighting the whole grow, or flower under a 50w blurple etc. Nice to know these things off the bat to at least prepare the op. Don't think it hurts to ask what light op is using.
