Thank you all for your reactions and help!

@Yves: I have found sulfuric acid in the local pharmacy. They can deliver a 4% solution. I hope it works for me. Thanks for your advise!

@maxxima: Interesting point you have there! As damp off is a major problem, it sounds obvious to keep the seedlings on low humidity during the first several weeks of their lives. Maybe till the 6 leaf stage?

@Greg: Sounds great! When exactly to you transfer the plants to your greenhouse (how many leaves)?

Cheers!

I've just sown about 100 seeds after soaking in 4% sulfuric acid for 24 hours. I hope I will have a better germination rate now!

I'm sure they won't all grow to adult plants. And if they do, I'll find a place for them ;)

oh my, 100! i made the same mistake, sowed about 40 thinking they wouldn't survive. well now i have 20+ seedlings and not a single one has died, they are literally everywhere. i'm pretty sure the remaining seeds will germinate as well come spring.

seedlings are very hardy, they can take 0C no problem. i even had a few covered with snow, nothing happened. they won't grow at such temps but they won't die either. by the way, they have no problem germinating in that range so you can keep some of them outside if space is an issue.

I had better germination then previous years using this method, but still very low. I think 15% germinated.... But they all damped off later... So still problems here!

Hi, very interesting post. :)

"How do you sow the seeds?" . There is another very good option: on wet paper or wet tissue paper, and another times into a glass of water. I never tried it, but a friend of DAEPC.org tried it with great success. :tu: .

Some photos of a friend who did it.

And another times, silica sand and perlite, or 100% perlite or 100% vermiculite it is fine too.
