i get it, i guess i still don't understand how voltage and temperature don't end up in the same place in the end anyway or maybe i don't get what's needed on the other end of the battery and lcd and that is my confusion.
i fully follow that one uses one and the other uses the other, but not why each specific is needed (i understand why herbs need heat and carts need voltage, but not why they can't be used for each other as they both = heat. for example, the picture in my brain shows my carts getting hotter, the higher the voltage. so why not measure temp to ratio of voltage and use the vv top for both. does that make sense? doesn't matter, not like my understanding or lack thereof will change anything material. thanks anyway for explaining.
Sounds like you're getting a grip on it. The next piece of the puzzle you're needing is the feedback idea. The herb cart actually looks at the result, rather than use history to guess like the second (VV) system uses. Consider that you could easily clamp your gas peddle down at some point on a flat road and get to a uniform speed. But if you hit a grade, either up or down, the speed changes and it our case you loose vapor or burn the load. Or what happens to your house temperature if you open a window and there is no thermostat to notice or care? It get cold where I live.
So yes, more is hotter. But we need to hit a target temperature within a fairly narrow window that's just not going to happen with an open loop system without serious user intervention.
Another way of looking at it is the herb cart is built like a volcano or HA (temperature controlled) and it too could get an air pump added and could then blow bags......THC, ya got your ears on???
8.5 inches in a foot?? Now that's silly.
$200 for a complete unit vs $59 for a cart.........what does that even mean?
Well, it's also $150 for 'a complete unit' from TV. Herb cart, your choice of 'batteries' to run it and the appropriate battery and charger.........what does that mean?
I think it means we have choices, IMO always a good thing for the choosers. The 'trick' is to make it an informed choice?
