if i have soil plants growing indoors can i take cuttings from them and grow them in my hydro set-up? and if so, can i do the opposite and put hydro cuttings in the soil(althought i doubt that one) any replies on this would be great!

eventually yes. there may be trama and it may take a few days to recover but you should be able to change the grow medium with little issue. I go from aeroponic to coco fiber until the clones root.

You can do it both ways, look in the growfaq under cloning they have like 10+ cloning techniques on there.

best if you figure your medium first but i have gone from dirt to rockwool and back with a single grow with no damage except its slowed the process. dirt to rockwool is a bitch if you're well rooted, really don't suggest doing it unless you absolutely have to. best to go with dwc if you're in dirt and neeed to change. tellin you though a good soil/medium is low maintenance and the easiest way to go.
