Seedlings are super tall

I started these seeds on March 30th. It has been 19 days since I have planted and about 15 since they all finished germinating. I have had them under a low watt fluorescent light bulb and then during the day I put them by the glass door/ (if the temperature is nice enough out on the patio). Is there anything wrong with the seedlings? They seem to be very scrawny and aren’t able to support themselves very well. I had to put some tooth picks and string to help keep them up right. (During week 2 I was out of town and so I only had them sitting by the window I don’t know if this may have contributed to them stretching).

If you have any concerns or suggestions I would greatly appreciate it.

These are the bruce banner autoflowers for reference.

depending on the light you are using. They are stretching for light. May need to put the light closer. Check out the grow guides for info.

They are stretching to get light. Which generally means you have a subpar light or the light is to far away. Usually both at the same time.

Is there anything I can do to fix it now or is it already too late? I’m only using a 1200 lumen 30ish watt fluorescent bulb. I was trying to go as low budget as possible. Is it a bad idea to put them outside (if warm enough) during daylight and then run the low watt bulb on them for the rest of the day? Or do I need to just buy a better light? I am planning on growing them outdoors once the weather gets a bit warmer.

Your plants are telling you that you do t have proper lighting.

What everyone else said. You need closer or better lighting.

Is there anyway I can fix this now with a stronger light? What strength/type would you suggest for only seedlings (I am growing outdoors only starting them indoors). Do they look ok besides the stretching? They seem a lot less developed then other peoples plants that are 2+ weeks old.

Of course as others said , need more light or bring what you are using , way closer until can put them outside .

When transplant, I’d bury the stem a good portion and be good as new.

@Joshmcginnis28 Ok thanks yea I should have specified in my original post that I know it’s due to light. I just wanted to know how bad it is and if it was past the point of no return. Does the growth look ok besides the stretching?

I think they look fine other than the stretch. Maybe repot them into something bigger and cover the stem up to about 1 inch and move your light closer.

Strain? Silica can help strengthen stems. Light spectrum influences node spacing, but they look stretchy to get to the light.
Otherwise healthy to me.

Hello and welcome to the neighborhood. What they said. Be watching for pests when bringing in and out. If you are going to put plants in a pot, i would transplant and bury the stem so the girls won’t fall over. Cannabis likes a good light and soil that is cannibis friendly. Depending on what zone you’re in, I would be leary to put out too soon. Have fun and good luck

Ya they are a big more leggy than I’ve dealt with. But being that you haven’t put them in final pots, I see no reason why burying the stems can’t fix this upon transplant.

I’d do that sooner than later , being autos , they are on their own time line. And any set backs can affect end harvest and yield.

Thanks! Yes this my first time growing weed haha. I will definitely be on the look out for pests when bringing in and out. If i am able to get them out their in the sun for a good 8-11 hours a day do you think that will be enough to fix my lighting issue or do I need to invest in a grow light. Last frost is May 10th in my area so I still have over 3 weeks till they can be outside for good. I am just afraid there not developing fast enough because their autoflowers I want to try and get maximum growth as fast as possible. Thanks for all the tips and I’ll bury the stems a little during next transplant!

Yes, auto flowers would be a concern at this size and time. When you transplant try to not disturb any roots. Be sure they go deeper into warm moist fluffy soil, closer to good light. They don’t need any more reason to slow down, cause they’ll flower ready or not :hourglass: 3-4 weeks from sprout. At that point they’ll have a completely new set of issues ( light, nutrients, environment).

Many will bury the the stem down a little. This will help so it doesn’t flop over. I saw you have tooth picks for stability. Which is good.

Other than the leggy stretch, they look fine. :+1:

It looks like you still have the netting on your peat pot, i would carefully remove the net and repot to about 1 inch below the first set of leaves.
