im want to try out s method ive been thinking of growing that involves a kind of semi hydro type of set up but i dont know if it could work.

the medium needs to be able to hold enough moister to last the day on a once a day watering schudule. im thinking lava rock pearlite and coco coir would be a good mix but idk. any suggestions?

the way the roots would be getting the nutes would be through organic teas?
if i do this would the teas need to be a bit stronger than if putting them into a soil based medium??

could root rot be a problem??/
