Re: [Aroid-l] Hot Water Treatment for Nematodes in Amorphs and a note on Spanthantheum

The commercial ones they use in labs run from about 700 - 3000 US dollars from what I've seen.  I like the idea of an aquarium heater in a bucket a lot better.  The commercial ones might be fine if you have a commercial operation or extensive rare collection.  For the poor soul who just wants to keep his collection of weirdness safe, a cheaper solution is better.  On an unrelated note, my Spanthantheum intermedium has a massive leaf this year after two flowerings.  It had started to make small bulbs (still attached) last season and one of them is also making a leaf.  It's quite impressive.  I know there were differing opinions, but I still find it quite easy to grow.

Dear Allan,

nor have I....

But I would probably try a big aquarium heater ( 50 - 100 W) in a 10 -
20 liter bucket and make sure the the water is aggitated somehow and
make sure that the bulbs/tubers do not touch the heater.

I will inquire how they do it in a commercial nursery.

Best,
Bernhard.
