Clones.....20hrs a day or 24hrs a day?

[ninesecz]

I have read a lot on both theories! Which one do you think works better? 20 hours of light a day and 4 off, or 24hrs a day constant? I know light causes photosynthesis but some beleive the 4 hour rest helps them become stronger???

*---20on/4off... only one way to find out, try it (even 24hrs on)
(18/6---20/4---24/0... no diff in growth time (imo)
