Grasscity - 420 Sale

600whps question

Discussion in 'First Time Marijuana Growers' started by captchronic, Mar 4, 2003.

  1. i recently germinated some seeds, i dont have any floros or anything so i put one under my light for like a day came back and noticed that the cotledons are turning yellow and that it kinda looks sickly im wondering if anyone knew what might have happened?
  2. Remember to keep the light a long way from delicate, newly sprouted plants. I would guess at least 4-5 feet with 600w .
  3. get a couple of cool white tubes I would say there still a little young to go under hps I dont start with the hps until there at leat 3 to 4 weeks old
  4. thank you 2 for the advice and tips
