Amnesia Lemon on Coco/Clay with Autopot

Germination: Unfortunately only 2 of 5 Seeds germinated 🙈🙈 so I ordered 3 more. I think i am out of luck with the germination ratio of my Barneys Farm seeds. I didnt feel i had these problem in the past. So the germination date and does not fit with all plants, but it does not matter i guess. If there is somebody who want to advice me that the pot arent standing safe, its to late, i already thrown one down where many roots have broken off. So this plant need some time to recover. So now i have two disabled plants. All the new seeds germinated and were placed in small pots with 100% Coco. The Grow Plan: This grow i want to try my luck with Autopots and Coco as substrate. Autopot recommends to use a 50/50 Coco/Clay Pebbles Mix. I think i will use a bit more Coco bc i'm afraid that the pots won't absorb the water properly, if there's too much clay in them. I will put the Autopot system into operation 1-2 Weeks after i potted the plants in the final pots. Facts Number of Plants: 4 Pot Size: 15L Veg Light: 150W Flo Light: 300W Grow space: 80x80cm= 0,64m² Watt/m²: 468,75W/m² I think this grow could be a bit of a challenge again, wish me luck.
