SulcataSquirt said:ooh i gotcha, Those pads arnt true spinless cactus pads, They have been despined by tortoise supply, so once you have your plant established it will start growing spines. If you want true spinless cactus pads the only person i know for sure to get the real ones from is Coastal on here, His site is coastalsilkworms.com, also the cacuts you have, you must be very carful handling pads straight off the plant, im sure you already experience the tiny spines that you cant see!
We don't remove spines from the pads prior to shipping.... Like I've got time for that!!! There are tiny spines on ours, and essentially all cactus pads. I'm not sure I've ever seen a cactus pad that was so thornless that I would rub it against my naked bottom (try not to make a mental image out of that one). Ours will regrow just fine and not have spines as they grow any more than the original pads.
The type of pads sold at RivenRock have less spines than ours, but they still have spines. We have a big patch of those growing here, but not yet to the point of selling them. Neither variety has enough spines that it's going to matter when feeding it to tortoises.
Side note, I wouldn't claim that they are good "down to 20 below" as the OP said.... The root trunk can handle some pretty cold temps, but at about 25 degrees (above 0), we were having the thinner pads freeze off on the RivenRock variety (which tend to be thinner than ours). The normal pads we sell are ok down to around 18 degrees and then they start freezing as well (depending on how long it is that cold for). Once they freeze, they basically die (turn real soft) and fall off. Like I said, the plant (lower, thicker parts) will survive some very cold temps, but if all the top of it freezes off each winter, you're not going to make any progress with it. I'm not sure I'd consider any of them great for Northern climates unless you can bring them in during the winter.
