M. R. GT,
Man those starts look killer. Why are they so short with so many branches? I do not see a light source in any pix. What kind of light and how far away? All the starts I have seen are like 2-3 inches tall with just the starter leaves and one set of first leaves. Even when these are transplanted and buried up to the first leaves they still stretch and never look as dense as your inter nodal length. Is it the genetics or have you selected for shortness?
Great thread and thanks for the info.
Not to speak out of turn, but really intense light does that, particularly if there's much blue in the spectrum.
I had the same sort of growth under a dual arc 1000w lamp in a 4x4 reflective enclosure & it's very much the same with my new system using two 315w CDM lamps.
