  1. Planted a seed ~8 days ago.  Has cotyledon, one set of leaves, and second set are just starting to show.  How long should I wait before I switch over to 18/6?  Thanks

  2. never, unless heat is an issue and it needs a cooling down period
     
  3. So I should switch now?  Sorry haha Im high and your answer is kind of confusing
     
  4. no you should not.
     
  5. Gotcha.  Thanks for the help!
     
  6. Leave kt on 24 untill you want her to flower atleast 3 weeks from now depending on situation and room size lights all that good stuff but dont switch it now wait untill your ready to flower her and put her on 12 12 good luck
    Introducing her now would shock the plant into flowerig early
