As I said previously, I would return with my findings on these generously suggested repotting methods, but it is unfortunately not going to be conclusive information that I pass on as I have had problems with my timer that just happened to coincide with the repotting of the plants, and so if they had turned hermie or stunted then it would be hard for me to determine that it was as a result of repotting as I have had some plants turning male and some hermies as a result of being an ignorant cheapskate and using a $4.98 timer to try and regulate 983 watts of light including a 600 watt ballast that spikes at 15 amps when it's only rated at 10 amps. Oh well, you live and learn.
Anyway, what I can report is, that as far as I can tell, none of the plants I repotted turned hermie and I gently pried them from their pots and placed them in the centre of some very loosely packed damp soil, (none of which had rooting gel applied as suggested, as I previously mentioned, I am a cheapskate), and there doesn't seem so far to have been any ill effects on these plants and they are still growing as before.
I think maybe the key is to handle them like they are sculptures made from lightly compressed icing sugar, that, with even the slightest amount overt pressure applied upon, will explode into a cloud of falling dust. Then it might work.
I'll update. Even if they all die.
End transmission.
