That's good info. Coincidentally doing my first outdoor grow this year as well. I usually germinate three and keep two (indoor), but I decided to hang on to the third and just see how it does outside. My mistake was not putting it directly in the ground like you did. She's in a 15gal and still under-potted, meaning I have to hand feed with solution, which is absolutely not something I wanted to do when I popped it in a solo cup on a lark. Next year it's in the ground for sure, so done with pots for my pot.
Totally get what you're saying re: batteries. For what it's worth, most ball vapes are plug in. Best analogy I can give is they're basically electric bongs. If you ever get the chance to try one, don't hesitate, I am beyond confident it will blow your socks off! For lawn-chair portability, I grab the tinymight2, and for anywhere else portability, I also still grab the rolling papers. :)
Afraid of setting a precedent where the rich are held accountable, no doubt.
