My four year old Adeniums are still about 5 centimeters high...

How long does it take to get to that size in your climate? It takes about a year here in our tropical climate.

My friend from another forum says he has ones that flowers within a year and a half. With heavy fertilizing and heavy watering during summer time. I didn't tried it yet, but have an intention to. My this years seedlings (3 weeks old) are now (biggest ones) about 5 cm tall. They are in an icubator on 12 hrs per day light.

Those Tephro. geometricus seedlings are FAT, but I think that's normal for them. Looks like everything's going great.

Thank you Dan. I am comforted now.

I tried it with a baggies.

Standing in water:

Placed in baggies:

We'll see if it makes any difference.

Standing in water? That's not a technique I would use, leaving them like that in a bag. The soil gets wet, not moist. Might be risky... I always place the pot in some water, let excess water drip out and then put the pot into a bag. Sounds a bit safer. But then again, your wet method might work.

I'm thinking this is a "language" thing, Aiko. I might be wrong, but pictures are telling 1) soaking in tub; 2) bagging & nuking(? - altho no mention of nuke); 3) add seeds after cooling? Is this what you did, Maja?

Well. Standing in water means soaking up, yes.

No nuke this time, becouse I got a finished mix from Zvone just the way he sows into, and he doesn't nuk - ever.

But Aiko is right. They are standing in water in their baggies , which I will correct as soon as I get home from work.

The "no nuke"(or not baked) would be a serious concern to me, Maja, unless all the ingredients were pre-sterilized. But even in the process of sitting out soaking allows dust/contaminants to settle on surface before seeds placed & baggies closed!

Maja, are you going to be a new supplier for nursery Astrokaktus?

I also didn`t nuke the soil and I open the glas from mini GH every day to sprinkle water on seedlings

Well Simona. Nobody nukes the soil in their natural hanitat, does it????

Peter no offense. But I think sometimes we DO complicate things too much, don't you think????

Definitely, but I'll let you use your "guinea pigs" & report your results. Seedlings in the wild also don't have 100% humidity for 6 - 10 months -- which is why some people like to "grow them hard" - slower, not very lush, but tough!

I always have a bit of standing water in all my baggies, from Ariocarpus to Thelocactus and many more in between. Plenty of so-called 'rot prone' stuff. Some species need it with the rate that they grow. It probably helps that my soil mix is very lean, though. They'll be fine, don't worry about it.

'Hardness' seems to be less humidity dependent and more soil nutrient content and light intensity dependent.

OK. Time for a little update.

I sow some Adenium obesum (and some hybrids) Some are small some are big:
But the biggest one is about 7 cm high (in one month):
I even sow some cacti. One od the most obedient kind is the hybrid of Astros Hendry sent:
One species of Tephros did well (while another kind didn't germinate AT ALL):
Bombax did well too:
Those are all 1 month old plants.

Nice progress on those! Since I pretty strictly grow cacti, sometimes I forget how fast other plants can grow! Nice!
