How Long before clones begin new growth ?

I took 4 clones off my Blackberry mother and placed them in a hydro system about three days ago using only a very light dose of rooting hormone with PH'd Tap Water . Either growth is extremely slow or just stopped altoghether... I know there is a stun period when taking cuttings does any one have any experience to share with this?
Ill posr pics when possible and im using a 250 watt hps Thanks !

For the next couple of weeks, your clones will be putting all their energy toward growing roots. Assuming all goes well, you can begin to see growth up top at about three weeks in. How are you caring for them? Are you misting them with water, etc.?

Oh wow weeks ? and no im not misting them with water They seem healthy enough they have been transplanted fro about 4 days now just seem to be at a standstill. They are just in the hydro tub under a 250 hps

Are they under a humidity dome? Without roots, they need to take in moisture through the leaves. Misting them with water and/or putting them under a humidity dome is the best way to accomplish this.
