First time indoor grow ??? 's

SO I DECIDED TO TRY AND START AN INDOOR GROW WITH PRE VEGGED BLACKBERRY KUSH CLONES THANKS TO CLONEVILLE.ORG MY LOCAL DISP/CLONE STORE BUT THE PRE VEGGED CLONES COME IN ROCK WOOL DO I HAVE TO INVEST IN A HYDRO SYSTEM TO GROW WITH ROCK WOOL OR CAN I JUST PLACE THEM IN THE TRAY AND WATER LIKE SOIL?? IF SO HOW OFTEN DO I WATER AND DRAIN THE STANDING WATER??? THIS MAY BE A DUMB QUESTION BUT I AM NEW TO INDOOR GROWING

You can drop your cuts that are in rockwool right in a pot of soil. Rockwool sucks IMO, especially if you are new to indoor growing, just stay away from hydro and go soil. You'll be much happier you did.
