SOG quick question

if i made trays 4 inches deep and filled with a mix of soil and hydroponic pebbles. then got cutting and put those in medium, rooted them then put them into a red cup (beer pong cup) and put those into the trays could i do flood system ??

I would think the soil that will inevitably mud up & drain into your reservoir mixing w/ your nutes & clogging up your pump would be bad. I would say rockwool to start cuttings in then all clay pebbles for medium would be a much better way to go.

Why dont you use just the pebbles and a grodan cube, rapid rooter,etc?Red cups are for flower Blue for veg.lol
