Some blurry pictures of seedlings still in baggies
I made the mistake of planting species in the same baggies for the sake of space, so that'll be a common trend throughout.

Copiapoa Marginata, huge success with these. Planted alongside Copiapoa laui which are just beginning to sprout Copiapoa tenuissima, only got one seed to germinate from these. Planted alongside copiapoa hypogaea lizard skin Leuchtenbergia principus with rust, the rust doesn't seem to be affected growth rate or germination as the pot it's next to is covered in rust but I'm beginning to see T. gielsdorfianus seedlings pop up. I think I'm going to keep them in the bag despite the rust considering I'll be gone for 6 weeks starting next month.

And last but not least, my winter growers.
Miscellaneous japanese haworthia hybrids and conophytum friedrichiea, i believe I mislabeled the conophytum photo
Any opinions on summer watering, my conophytum has visible sheaths and the haworthia are small but at the same time I don't want them to dry up or rot. I gave them a sprinkle last week because there was cloudy days on the forecast. Should I continue watering over the summer or let them go completely dry like older conos/haworthia?

Speaking of open bags, I think the "red rust" is fungus/algae/slime mold? I had one pot develop something like it last year.

It seemed like whatever that nasty looking stuff was didn't affect the seedling? Unfortunately I don't know how the seedlings would've fared long term in the same pot since I ended up grafting them.

I might just go ahead and open the rusty bags. It's definitely not slimey, I had one unsuccessful pot with the red rust, and its like thin papery rust that develops at the very top. Probably a fungus.

So far all my seedling pereskiopsis grafts have been unsuccessful, I think I just need more humidity because the seedlings always dry up first. Might to a mass grafting once the baggies are completely dried out.
Leuchtenbergia is definitely going to look weird on pereskiopsis, hopefully I don't have the graft them.

Fun isn’t it

The reddish stuff on the surface of the media is undoubtedly red algae - perfectly harmless. I've had it grow in some of my seed pots, no problem at all.

Thanks, I've never had red algae before, it's usually blue/green algae for me. I think it may have to do with where I collected my sand from.
