I wonder if someone can help me here. I have been cloning from this motherplant for about 2 years..no probs most of the time..but lately all the clones die, when under 18 hour light.When I take them out of the box and put them in a glass of water and back under the light,they miraculously stand up again..and will stay like that for weeks..but nothing happens..no rootgrowth...put them back in the growing medium and they collaps again.:( any body please ?
