How stretched are the stems?

If they're more than 3 inch, kill them, and start again with all CFL's.

Make sure they are close to the plant, very close, within 2 inches, and amke sure the fan is on the stems to make them strong.
LIP Reviewed by LIP on . USE CFL FOR STRINGY STEMS? I was stupid enough to use a CFL and a INCAD for light early on, and now I have very stringy stems. I just bought a 70W HPS and more CFL, and I was thinking I should turn off the HPS for a week or so until the stems get stonger? Should I ? Then turn back on the HPS. There about 10 days old and barely salvageable at this point...But I think there savable. Rating: 5
