Re: Orostachys

Where I have seen them growing wild in China, they probably get rain all the year round. They dont come from deserts. They probably go dormant due to cold, not because of lack of water.

Re: Field Number Database - more additions

I've now added many GBG numbers, from the German Brazil Group. These are of the form GBG81/100, etc.

To see who was in the GBG, search for GBG on the collector finder page

Re: Orostachys

China? Japan? That's where they come from... :lol:

I've seen one species growing wild on old walls in China.

They are short lived, and flower themselves to death - but form offsets before they do so, if you are lucky.

Sorry my answer is not more helpful.

Re: Remote wireless thermometers

if you are handy with electronics :cool: you can build yourself a wifi connected thingy for peanuts - you need an ESP8266 board (e.g. nodemcu) to do the wifi and run a basic webserver, and a DHT11 temperature / humidity sensor. The bits should cost well under a tenner from eBay etc.. Some ideas on h...
