I'm noticing less condensation on the bag, when should I rewater/spray these seedlings? Also I used 3% hydrogen peroxide to start them instead of water, can I water with hydrogen peroxide again or should I use regular water?

thanks

Best to keep cactus seedlings evenly moist in the early stages. What I do is open the bag just a little bit and squirt some water into the bottom of the bag when it appears to be getting drier - that way there's no danger of getting them too wet, the mix won't wick up moisture beyond the point where it's just moistened. Just use water for this, peroxide would need to be sprayed directly on the surface to do any good, and you don't need it anyway.

I agree! Bottom watering would be helpful. Btw, where did you order the seeds from?
Tropical weather, no winters! :roll:

Seeds are from Cactusstore.com.
These are being grown outside, under a shade cloth where they get direct sun for 6 hours. For most of the species I ordered I had a 80-90% germination rate. For turb. Polaskii "la bonita" I only got 1 out of 10.

Lots of South African Seeds started this winter, tags disintegrated in the winter rains but I'll know what they are one day.

Noticed a rotten T. klinkerianus seedling, don't know how long ago it rotted but might've actually been recently due to the cold weather. Temperatures should start going back up soon. All my winter growing seedlings are loving the weather though.
Repotted all my turbinicarpus seedlings to a soil with about half of the organics the old seed starting soil had.
Noticed some other rotted ones. Hopefully all the survivors stay alive. Still have a good amount but they are hard to see because the top soil is mainly pumice.

Some turb seedlings had rotted out too much and the rest dried up, i definitely went too low on organics and messed up by letting them get too wet in the winter. They all died, but a bunch of new species are up and going, won't want those mistakes again.

Seedlings pics, couldn't find my hand lens today

Lost ID japanese hybrid haworthia seedlings, a lot didn't make it for me, but my friends did. Luckily there are some survivors,

Yea they can rot easy too much pumice rotted many of mine they did well in a soil based mix meaning soil and pumice 50-50% . Same with Ariocarpus.

That's interesting, it almost feels as if they would more likely rot with too little pumice? Feels backwards but it makes sense for a baby plant that doesn't have an established water reserve.

Been feeling really discouraged as I wasn't seeing very successful germinations, especially since Keith was kind enough to send some seeds. I sort of just let them sit and forgot about them. As of lately I've noticed many seedlings sprouting and some seedlings growing at a fast rate. Most of my species are sprouting now, nd I feel accomplished. Even little aztekiums are popping up.

Only I'm having one issue.
Some of my baggies developed red rust on the top sand. What do you think I should do?

It really is amazing how attached we can grow to our tiny green blobs. Objectively, we know that seed is cheap and readily available, but I couldn't help but feel sad the other day when I found two of my largest 4mo. old Mammillaria pennispinosa seedlings split down the side with nasty red jelly inside. I decided to leave that bag open to dry out the surface.

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

A pot of Epithelantha bokei from last July. Nasty.

I left the bag open on that day and here is the center seedling a month later.

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.

The most appropriate action seems to be to keep a baggy on recent graft for a day or two and then remove it. Some fungicide or sulphur powder over the open cut as well.

And yes, Turbinicarpus seedlings are moisture-sensitive and grow very slow. I kept mine in fully mineral mix and sterile sealed baggy for the first year or two. Plus warm (heated, indoor) location even after unsealing their pots.
If your cacti mess in your job just forget about the job.
