Now that is interesting! Something I never considered to boot. I'll have to dig into that, @finnian. You can school me in discord or steemitchat hopefully..haha
It does make sense that sunlight plays a role in the production of vitamin D in living organisms, whether an egg or mushroom.
As far as the 'programming' goes, that is partially thanks to the mega-money food industry - they tend to share more info about the dangers of your food you grow, than the stuff they sell..Ironic isn't it? It is a skill that is looked at as 'you have it or you don't' but that's long since been true. Maybe before the Internet, but there is so much info daily available for anyone that seeks it out, it is there!
Just about every household around me grows a garden in some capacity - flowers, food, or just a couple plants in pots. Yet, they all approach it differently. What I mean is they all have differing methods, but generally the same results, regardless of methods and practice. They ignore very simple knowledge that experts have shared and is a search away from their eyes. I approach gardening as if I am a student, not a master. I accept that I do not and cannot know all I need to know and I seek ways to improve. I never say "well, I got 29lbs of tomatoes off of one plant, but the avg is 10 so that must mean I have maxed out the yield". I say "29 is good, but 60 has been done. Let's try for 60" 😉
I hit 52-53 last year. Better make it 70 lb /plant this year because I saw a guy doing 90's with similar practices. There is always improvement and likewise a challenge to accept.
Start small and build up your knowledge and tools..once you have those, you see far less resistance in growing. Once you can grow plants, say a tomato plant, and eat your first fruit - that is going to fuel your desire to continue. Once you grow so many others start telling you how delicious they are - that is going to spark something that one can easily use to create business.
Anything is possible. If Disney can grow 60k tomatoes on one plant, I can too (just working on getting that budget up there..hahaha)
