For most, since the beginning of time, MAN went to 'hunt', while the women remained behind to forage and prepare. Eventually man began to discover the fruits of cultivating the land and enjoyed the benefits it beared.
Nowadays you will find both men and women learning to cultivate not only fruits and vegetables for personal use but also a (common) "weed" in a variety of methodologies. Albeit terra, hydro, misto, indoors, outdoors, in greenhouses or closets depending upon location and need. As a Farmer in the rural parts of the county, space, like law enforcement, is not an issue, especially now that cannabis has been legalized (not to be confused w/decriminalized) for personal use in most States.
So, what is needed?
Just like growing anything else; space, seeds, soil, water and nutrients* oh and of course TIME.
