That's where I got my seed from - Italy... but only one seed for $10.50 is expensive, and still I'm not sure it is a seed growing, its sooo small!!

well this one is still around. hasn't changed much though, very very slow. a couple more tiny spines if viewed under a magnifying glass Laughing

no, mine looks more like a green fleck, very green and has some tiny white spines in a clump on top. Can't take a photo, it is too small.

well... im trusting its the same... being from the same source, possibly even the same seed pod! Laughing

they are probably siblings.

Just out of interest Lewis and calycium; how long did your seedlings take to germinate? I have also planted some recently and have yet to see anything green Sad

What is the ideal temperature to grow these little stunners?

mine took about 3 days from memory. 1/5 is alot better than none. the plant just has a poor germination rate, i have talked to many growers who have sowed 10 or 20 seeds and got precisely zitch germination. i'm not usre about the temp as i don't have a thermometer in my propagator.. but im guessing its about 25-27C directly on the heat mat.

Thanks for that lewis. I will try dropping the temp a little as it is at 35c at the moment, been in there for over a week now and they have not yet starting to grow.

All my astros have germinated in this time which leads me to believe that I will need to purchase more seed and start again Sad

Was so looking forward to seeing them grow. Oh well maybe next time

Huggie,
my temp is set on 28 degrees, but I vary it between 27 - 30. 35 is too hat. My first one took about 5 days (and I think I have just had another germ agter 2 weeks - happy)

Still very small, and almost looks like a tiny clump of white fungus.

Huggie I agree with calycium...........I have mine at 30 and germination seems better for me at this. Since I have upped it from 26 I have things starting to germinate that have been sitting doing nothing for 6 weeks or longer (not cacti though) Most of the seeds I am sowing now like a little more heat.
