Question
how easy is it to cultivate cannabis plants? What is your recommended time for vegetation before going into flowering?

Answer
Hello Omac,

It is very easy to start cannabis from seed.  I have no personal knowledge however of length of time to flowering.  I think that would be dependent on light conditions more than anything else.  Also, (if grown for) mind altering chemicals... the female plants have more THC content than male plants although male plants do have some.  Until flowering it's not possible to tell them apart.

There is a book I read long ago that had detailed instructions for growing the plants.  Try doing an online search for more info.  I'm sorry I couldn't be more help to you

Peace
Chris
