Seedlings stretching

Discussion in 'First Time Marijuana Growers' started by HydroBeginner, Jun 3, 2011.

  1. they're in humidity dome, about a week old, not far from top of dome.

    Using a 35 watt gro lux tube..

    would love some help?

    PLEASE
     
  2. Give them more light. Stretching is from not enough light.

    Be sure to transplant into larger containers when the 3-bladed leaves start growing in.
     
  3. I was told to leave them in the humidity dome for two to three weeks. Is this wrong?

    Should I put the seedlings down further into the medium when I transplant them? To bury some of the stem? Does this become part of the root?

    Also, I have a 600 watt metal halide, should I put them under this light now?, and at what height above the seedlings?

    Cheers
     
  4. Lower the light source.
     
  5. They're in dome at the moment with 35watt light right on top of dome.
     
  6. Thank you
     
  7. Yeah if they stretch bad like that its a very good thing to do. You should bury up to the bottom of the two round leaves (the first leaves that came out of the seed shell). This will help you out alot. For one thing your plant wont look so lanky, and it also helps keep the plant more stable, healthy, and it just looks better. :D
     
  8. What he said^ You are correct in assuming it becomes root mass. It will shorten your plant several inches(over the course of the grow) as well so you can grow it taller.

    The part of the stem under the cotyledons would continue to grow taller wasting a lot of space if you didn't bury it.
     

  9. Once the plant has its first set of two leaves take the humidity dome off.

    As for the stretching..there streching for the light. Move the light closer.

    Yes you can pack some soil around the seedling to cover some of the stretching when you transplant.

    Sure you can put them under your MH light. I would not have it close first couple days till your seedlings are transplanted and happy in there new pot. Once they are how close a light gets is alot dependent on your set up.
    With a MH/HPS you can only have it as close as your cooling allows..they generate alot of heat.

  10. Thank you,

    Do I need to wean them off the humidity dome, before transplanting? Or just take them out?
     
  11. just take them out.
     
  12. Thank you for your help everyone
     

  13. Take it off. THe humidity dome really is only there to help aid the transition out of the ground to the 1st set of leafs. When seedlings emerge there fragile. Oviously in nature there is no humidity dome but it gives the seedling some protection. Once it has its first set of leaves and your giving it plenty of light you will have rapid vegetative growth. In 2 weeks you won't believe how fast your little mjers look.
     
  14. much appreciated, thanks guys
     
  15. Not a problem everybody starts somewhere where just here to point your and your plants in the right direction
     
  16. Cheers,

    So, when do I need to start adding nutrients to the water I give them?.
     
  17. I think I have the same problem, they kinda stretched, so there's about 5-6cm (2-2.5 inches) from the soil to the first set of leaves. Do you guys think I should bury them or just add a bit of soil around the stem?
     
  18. I think the guys have already answered this question.. .

    Check the posts above mate..
     
  19. My bad, my question was: is 5-6 cm an indicator that they stretched? How do you know when they do/don't stretch? I take it it's big enough to be burried?

    Thanks
     
  20. Is all good..

    It sounds like you're at the same point I am.

    I would assume so yes, that is what the guys told me.. . Bury some of the stem..
