What's something non-toxic to plants I can use as sealant?

I have a daisy aeroponic cloner and something in it cracked so I need to seal it with something to stop it from leaking so my clones don't die.
 
How long does it take for that stuff to dry and not come off? If I just put the clones in water will they stay alive?
