Dude that sucks.
Do you want a Bonda Ma Jacques? I've got one spare about 40cm tall in a bucket. I would offer more, but I haven't had the best first season either, and that's the only plant I have more than one off.
You know where I live, and you could grab that kmart brand a/c as well...
I vote for outsourcing the Bonda Ma Jacques to megamoo's uncle.
I was going to take some pictures of the sick ones but its not a pretty sight cos I've stopped watering them.
Do you still have plants in the potting mix that held water for several weeks?
