I've never had a problem watering once every two or three days with large RW cubes and slabs. Really you shouldn't have any problem setting up a reservoir underneath and running a constant recycling drip system if you really needed to, but otherwise make sure the bottom inch of the cubes is in the lava rock or whatever you use for a base substrate so the roots have a space to hide from the light.
khyberkitsune Reviewed by khyberkitsune on . SOG question Im about to start a SOG setup and I have a question. I have to hand water the babies cause i have no room for anysort of automation. i picked up 6" RW cubes and have four side by side in a tray. i dont want to put just the RW in the tray cause im afraid of algea forming on the bottom of the tray. i was wonderin if i could put about 2" of lava rock on the bottom and place the RW on top of that. would the roots grow together and fight with eachother? There wont be any veg time, once the clones Rating: 5
