I go back and forth as to whether its duration or intensity of light tat
makes our plants bloom.. I think the answer is qualified 'yes' but if
one was to err I think it would be on intensity rather than duration..
I think plants need a minimum of light but it has to be of a certain
intensity. 8 hours of non sufficient light isn't equal to 8 hours of
intense light.

Or am I nuts,?

Has anyone any input on intensity vs duration?\
