How are you dear friend @solominer
It's a great job you do to water your plants, it's good that you have the mini charger to transport the water tanks.
Rainwater seems like a great idea
Shall I consult you? You have not thought about drilling a hole in the ground to extract water from the soil for irrigation, here in Argentina it is widely used in orchards to irrigate plants.
I am doing good, yeah glad I have a system down.
Oh cool, I would need to look into that technology some more but it would be promising.
