That right there is 1 million percent my way of thinking :D There is a "fine line/balance" that can be found with any single thing you try to do. And that line is what I search for.

If I can't get any color changing response then I will definitely look into more lighting and more cooling for the chamber.

Sorry been unavailable for a while. Update time.

Due to all the outside stuff going on I failed to fertilize the Parodia very much and probably left the in the bag to long. Lost most of them. No biggy, was all part of the learning.

Overall horrible germination rate :(

Would like to know if the size is about right for the age. Do not know if they are growing slow or fast.

Germination might be low, but what you have look great. Besides, you didn't really want 1000 Parodia anyway :lol:

Yeah the Parodia where just gonna be give aways if they made it.

Have a batch of A.Myrio Hakuun that didn't germinate at all. Have them drying out and pulled the couple that had obvious problems. Hopefully some of them will pop with a second try, or a 3rd if need be. Is there a average amount of time to let them dry out before trying again?

I'm only in my 1st sets of propagation (Jan 5), so can't help you with that. Lots of other experienced propagators will help! :D

They look good for that age.

Leave them dry for a few months if you can.

Looks like a possible problem. Just noticed this yesterday. The side/base is developing a crease and sinking in. It appears to be worse today then yesterday.

Pull it out to see whats going on with the root system? Possibly to much or to little water? It seems to be a little soft at this are if you press lightly on the side of the plant. The rest of it still feels firm.

I have to admit that the top dressing layer of turface fines are not wetting like it originally did. Not sure if this is due to a build up particles from the distilled water that I am using. Instead of the water just wicking right thru it is tending to perch on top for a bit before soaking in.

Edit - Forgot to add, water frequency is every 3 days, watering thru. 1/4 strength fertilizer. Skipping the fertilizer every other watering.

Hope these pictures show it properly. Not the best lighting.

Well I felt like I should act now. If it was the wrong thing to do, then so be it. Not every seedling is going to live, lol.

Looked over Kada's page on seedling problems and this sure seemed to fit dehydration. I just watered the container yesterday, and when I emptied it out the whole thing was bone dry. I am guessing that since the water was perching on top and not soaking in that the water coming out the bottom was actually just running down the sides and not going into the mix.

Was not expecting to see much of a root system but this is what came out. Had no idea they could do this much in such a short period of time.

Re-potted in about 2.5 turface to 1 sand. Should have a much better water retention now and no more top dressing. Did the same with the Multicostatus. That root systems was just as healthy. Both water straight through like they are suppose to. Just need to see how long it takes for the new mix to dry. Am thinking it won't be much more then 48 hours. Will weigh it and find out.

Its only been about 5 hours since the re-pot and both of them are already raised above the line they started at and the deflated area is filling in.

They look fine to me.

What I do is use 3.25" pots and 6" bags, which fit perfectly. Then I sow about 50the seed per pot, 2@25x or 3@10x seeds in rows, trying to match species with similar growth rates yet are easily differentiated when bigger. Small pots in bags dry out too easy, bigger pots provide a more stable environment.

I've found Astros to be relatively fussy cacti, don't be frustrated by them too much. There's a reason they are often grafted.

They both have responded wonderfully to the re-pot. The Astro is nice and filled out again and signs of growth on both plants.

And not stressing at all Spark, actually have a ton of fun working my way thru this :)

Kada (loph) recommends a mix that dries in 1-3 days and these have gone bone dry in just under 3 days, so I think I may be in a good spot with that. Going to start lengthening the dry time in between watering now for these couple. I still have probably 3 months of solid summer and the winter here is generally pretty tame. I may try to move these 2 outside in a few weeks.

Never to many, not anymore, lol.

:::::::The rest of this are my finding and do not represent the "best way" to do it, or the "correct" way to do it:::::::::

So here are how the kids turned out. These are the same 7 cacti from the previous pics. What were suppose to be Hakuun Myrios turned out to be a mixed bag. One is Columnare, another seems to have Capricorne in it. And a few Nudum Vars. The E.Multicostatus really reacted great to the outside ligth.

One thing learned, DO NOT use any top dressing the is of a particle size less then 2-3mm. So take your <1/16" turface etc. and put it in a flower bed, imo. It is going to do nothing but turn into a layer of concrete and try to choke out your kids.

On the fertilizer side if things I can not speak for what you are using. For me I had to cut way down on the concentration in order to avoid literally plugging my turface with deposits. And that was at a 1/8 cut. So I wil be going for around a 1/16 mix or less and mixing in straight water.

Will post another thread on my year end result pics. Got 229 cacti out of 480 seed. Just finished re-potting today and moved outside. Bad light though, will take pics in the morning.

I hope this was of some use to someone.

They look awesome! :D A great experience of growing from seed, I'd say. I reckon those seedlings would like more light if they can get any, though. :)

Happy growing!

There is always one more glochid. Somewhere.

I've found the 'nudum' myrios seem to like a bit less light than their flecked bretheren, I think the flecking provides some sun protection and without it they are more susceptible to burning.

Working them into the sun a little at a time, and no signs of burning yet. Not trying to rush it :wink:

Yeah I figured that would be the case and will place them accordingly, thanks.


Was going to do a separate thread on the total results, but I will just put it here to kind of "complete" the thread.

Here is everything accept the Ortego's, which are still under lights. They need a few months yet before I will be happy moving them out.
