Also impressive. Are you using artificial light? What's the potting medium?

I use 25% ordinary flower soil and 75% cat litter clay. Yes, all my seedlings for this season grow in only LED-light and they have around 30 deg C in daytime and around 20 at night.

All the plants was transplanted into 6 cm pots a year ago. Not an easy task because of the hooks.
It is now circa one year and eight months old, give or take a few days :)

I have just looked at all the different threads of your seed sowing and your plants look great. As a relative newbie to this I have not had to transplant any seedlings yet but I can see it would not be easy with those hooked spines. :grin:

Hook spines are always trouble, i ve had the same issue with guelzowiana seedlings. It was not so easy to seperate 9 seedlings in 9cm square pot.
Your plants look very good!👍
