yep, i need a timer. short term memory is gone!
i'm a stoner, living in a bus on a hemp farm.
here is a picture of the days work. as you can see, its running.
it didnt feel very warm by hand, like electric blanket on low, so to speak.
next week, i'll plug it the morning before i go dump, give it a few hours to work. temps are only going to get colder here, and i'll be lucky to have days above freezing soon enough.
its wired to the negative and i have a little spring battery clamp on the positive side until i get a timer.
