@Kenough, I water them a little bit every day when they're seedlings. I water in little a circle around them. I don't start dampening the whole pot until they're quite big. Too damp and they drown or get injured when small.
@Nickeluring, Hmmm. I always air on the side of caution so they don't dampen off. Would you recommend watering them with more than 300ml every few days during the seedling stage?
I noticed they grow much better if I soak the whole pot completely.
@Kenough, one thing I noticed that can make a massive difference with autos is how they're being watered during their first couple of weeks. If they have a perfect moisture level they grow way better.
