Rory - it is on a back burner for a bit - almost every one of my planned experiments are - as my garage demands clearing out - this wouldn't be a large problem except that I am storing a bunch of stuff for my sister- who....... promised.......without a doubt.....this time without fail.......For certain, honest.......to pick up all of her stuff over the Christmas holiday.
all the cut parts are in the freezer and that is exactly how far I've gotten. Hell, the new cuttings have put on weight - some are a good 7 inches long - wish I had known these things grew that way before - if i had, I'd have had a hell of a lot more by now. Lessons learned growing cactus are sort of unforgiving. IF it takes you 6 years to learn something and then another 5 to put that new thing into practice, it doesn't leave much room for mistakes.
I mean, I sure would like to have enough of the end product to give to my friends even if I have to have them distributed to them at my wake.
