SledgeH Since the 8th, I've been watching them come up from the soil. For the seedling phase, I'm using a simple 10-watt LED. Interestingly, that was enough for all the other seedlings, but Purple Lemonade seems to need a bit more light; in a previous failed grow attempt, that strain was the only one that stretched. So, I added a small no-name growth lamp at 11 watts before they go into the tent with the proper lamp.
Due to previous problems, I could use some tips from the community here. My seedlings tend to stop growing shortly after the second set of leaves begins, about 8 days after germination. As you can see from the yellow sticky traps, I also had a fungus gnat problem, which I think I've managed to get under control. (7 gnats on 6 yellow traps in a week) That's why I used Seramis as a topping, and I also soaked the pot with a neem preparation before planting. The plan is to not give any water for the first 2 weeks. Unfortunately, I already lost one seedling with this setup. After 2 weeks, but as mentioned, it stopped growing after about 8-9 days. It's possible that the Seramis layer was too small, which is why the fungus gnats came back. But maybe someone has a tip.
