After 4 days they all rooted fully through the plugs and were ready to transplant. I transplanted them and set the lights to my seedling cycle (2h sunrise to 60W, 8h 60W and fading back to 40W sundown). Picture was taken on the next day without their humidity-domes. IMO doing its job on the leftover leafs/mulch and the first cover crop is also germinating.
I hope there will be some sunny days ahead so I can recharge the rock crystal and the aventurine for this run.
