I was just reading about how uninsulated black pots aren't the best idea, especially with LFSM. But I don't really have any other appropriately sized pots at the moment, let alone insulated ones.
So I'm wondering about some potential solutions, at least temporarily before the plants acclimate to full sunlight and it starts getting really hot out. Silver/reflective duct tape around the outside, maybe?
And one more thing, should I avoid re-repotting them anytime soon? Or should I transplant them (along with the media) as soon as I get appropriate new pots?
