Indoors is the only way to have a non stop supply really. Outdoors weed is a seasonal crop. Plant in spring pull end of summer/autumn. Could try staggering autos outdoors for a continuous harvest but fuck autos. If you go autos outside over winter you’ll have to watch temps, frosts and mould during flower.
The only thing that changes is when the outdoor season is. The northern hemisphere starts outdoor season as we finish and vice versa.
For a newbie starting an indoor grow id suggest either a living soil or if you want to go down the hydro route start with coco. Full reticulating systems like dwc, flood/drain etc can get complicated and things can go wrong if your not sure what your doing 100%.
If cultivating for medicinal use, you want to a. Select the right cultivar that will produce the best cannabinoid/terpene profile to benefit your Dad's condition and b. Grow the healthiest, most vigorous and lush plants you can. Grow indoors if you can .Avoid using synthetic fertilisers or pesticides as cannabis is a dynamic accumulator and will absorb heavy metals etc... look for fertiliser/ soil products that actually state the ingredients and have any sort of certification. Read Marijuana Botany, Teaming with Microbes... Hope that helps.
