This is my first post after reading through the forums for a while now. I have a couple of questions, and was hoping that someone here could help me out. My plan is to have a small solar panel charging a battery in the day time. I would like to run of of this a timer to control a pump. I was hoping to use an old windscreen washer pump but maybe thats too powerful for my purposes? Basically im trying to construct a very miniature hydroponic system for growing chillis on my windowsill. The pump will need to run about four times a day for however long it takes to fill two small pots with nutrient solution, i am thinking no more than a minute.
So i guess my questions are, and sorry there are a few..
- What sized solar panel would be suitable?
Would a washer jet pump be too powerful?
Is it possible to buy dc timers? (I had a quick google but only found 12v, not sure if thats suitable?
What voltage/amperage battery do you think i should use?
