May 31: visible roots showing so it looks like the third try worked. First two attempts failed due to water overheating from pump running too much. Cycle time 1 min on and off for 4 min has worked.
June 1: taking best rooted clones and planting in ProMix HP. Still fragile for a couple weeks so kept in shade out of direct sun in afternoon and under fluorescent lights (17/7 cycle) overnight. Clones supposedly grow faster than plants from seed once rooted, but I’m surprised to see obvious foliage growth after just half a day.
@Captensmokey, yeah I’m looking forward to trying it. The mother plant got too big to do light deprivation in July so it has barely started flowering. Hopefully that makes it, but at least I’ll get nice flowers off these clones. Cheers.
