To give you an idea of the system. A five gal. Bucket acting as a water tower,hose leaving the bucket going into a watering bar (by gravity) with several watering nipples.on the other side of the bar will be the pump. The pump I found (bayite byt-7ao14 12v 0.7a) will turn on with heating element (dernord 12v 150w #dnjf150161) circulating heated water to the top of bucket,this will be controlled by temp. Control ( bayite tcf-3a035,I need to check on that). Some simple lighting, maybe a little camera.
Run time ?? I need to go with a budget. Good call on low light, it is in a wooded area. I was thinking, would it be better to go with better quality ( lithium) and less run time? And safe. This is just a fun project, I cannot spend a lot , thinking around $400
Enjoying learning curve and challenge.
Can we hook up also a small windmill? I am building one.
Thanks for your help
