^Thanks. Some good info.
In TX it seems I don't need a license to sell unless I am acting as a 3rd party selling products that don't typically grow in TX like bananas and kiwi. Outside of that I should be good.
I am looking at ways to do indoor aqua/aeroponics to grow fresh food year round, for my personal benefit, and finding ways to sell excess. Initial start up is expensive though to do anything significant since legal crops have a much lower profit margin.
Building a room in a barn/shed isn't the expensive part. Insultation is like $100, and mylar reflective sheeting would be like another $100. Adequate lighting and accessories is where things get expensive. I have looked at Metal Halide/HPS and LED. Not all LED lights are created equal. The best ones out there that yield the best results are like $1800, (and I would need like 5 to do 100sqft). MH/HPS is cheaper, but requires a lot more equipment like cool tubes with fans and ducting, (they get hot), replacing bulbs every 6mo, (good bulbs are like $70/pop), ballasts, and use more electricity. I spent all weekend doing the math...it was pretty exhausting. My main drive though is picking the nutritious varieties I want that you cant find in store, and having them year round. Decisions Decisions.
This setup would be a little over $5k...but man, is it neat.
