Hi umbre. This is your first time growing? I've had difficulty with some of my seeds, and I was germinating 8 at once. In the end I had to do some 11 seeds, to get a total of 7 plants, and I'm not even yet sure if last one will work or not. What i'm saying, and take this with a bit of salt 'cause I'm a new grower, maybe you should be ready to germinate another seed, its only been 10 days since it sprouted... And try some things with this one. In this instance, I would advise giving her a good watering, leafs will be droopy its ok. Let it dry. See if it recover from that. If not maybe it was a problem with this particular seed, and the next seed of this strain will go better.
Slow growth? I feel like telling you, actually its not slow, you just don't see it 'cause its happening under the soil. Right now she's developping her roots nicely, give her a few days then she'll start going on with the leafs again. She looks very fine for a 10/11 days old plant! You should see my 18 days old... Tsss, a failure. I can't/won't throw her, but neither can I hope for her to give me anything good/worth.
