The fantastic four

Seeds all germinated very well. Little happened in the first two days, after that Nova and Euforia in particular really stepped on the gas. You can see, they want to grow. Are now in normal seed pots. I want do a experiment with this grow. I wanted to minimize the stress of repotting for the ladies. However, I also realize that a plant that is too small will not work in a pot that is too large. That's why I came up with the idea of ​​dividing the pots into different zones that can be enlarged depending on the stage of the plant. This way you can only water the areas that are used and it doesn't get moldy. These are open at the bottom, so the roots can penetrate downwards. If a ring is then removed upwards, not all roots have to grow again. Then I wanted to adapt the earth to the corresponding growth cycle in the individual areas with their respective Vördung. That is why there is 100% BioBizz Light Mix soil in the innermost part with a diameter of approx. 7-8cm. From about the 3rd week, the "pot" is expanded to about 14cm. With 50% LightMix and 50% BioBizz ALLMix. Softer transition. Towards the end of growth, the range is then expanded to the 14L pot, which occupies most of the volume and contains 100% BioBizz AllMix. Will it be something? I do not know. The whole grow is watered with rainwater from the cistern. As soon as the first heads come, I slowly dim the light.
