With 2inch pvc pipes and some Y connectors, I made a small prototype of fogponics.
Using a 24V ultrasonic mist maker that I bought from Alixpress and connected to my 24V solar off grid system. I used small blower from cpu to push fogs up to the pipes. The blower is 12V so I added LM7812 so the blower can be connected to my 24V battery.
I am trying to experiment specific nutrients for these plants.
I replaced the hydroton pebbles with sponge so that fog will rise up to the top hole.
