Buy seeds and start out small. Get a good relationship going with an indoor garden supply retailer and they will be way more helpful to get you to your goals than any investor. They want to see you succeed. If your garden is productive then they make more money. The money you spend will be offset by your productivity. Of course you will need to be responsible for your own market end of your business. Investors will tell you how and where to spend. When that comes from someone that knows little about gardening the results can be disastrous to said gardening/business venture.
This is so basic it hurts. I am preparing to start growing for my second time and though the first went really well, I am still nervous and definitely wouldn't feel right promising returns in my position, let alone yours. The market here in Cali(northern, at least?) is rough, gotta have some fire if you're breaking in I'd imagine. Results will get your help far faster than posting "ready to grow".
Nah...as long as it's OG or an OG family you can sell mediocre to garbage weed all day. CA weed market is like the beer market....98% IPA the very idea that anyone would like to drink a beer other than an IPA is just totally fucking beyond Californians. Ask for something yeasty/red/creamy/not an IPA and you'll just get this dumbfounded look from your beer supplier. Same with weed, OG weed, any OG will do as long as it's an OG cuz that's what snoop talks about west coast!! Doesn't matter if you have the most unique wonderful tasting high THC *insert any other strain name here* they don't want it and even if they do they will pay you shit for it. If you want to grow commercially and grow something other than OG don't come to CA, pick a different state.
