What do you mean by "soil hybrid"?
I have been looking for something that will allow me to leave my plants for an extended period and I think that I will end up getting a Growtronix automation unit along with their "soil sensors"
http://www.growtronix.com/store/index.php?route=product/product&path=4&product_id=22 . The Growtronix will control everything including the light schedule and when the soil/coco hits the preset dryness level the "soil sensor" will recognize it and cut the water pump on for the drip feeder. When the soil/coco hits its preset saturation level the Growtronix will cut off the water pump. It sounds good in theory any way. Hopefully it will work out that way
