I am planning on growing a bunch of pepper plants. The photo above is my setup from last year. A grow bag, placed in a box. The box is filled with 3 cm of water each day and the coco wicks it.

I want to use less plastic this year, so i want to place the peppers in the ground and add the masterblend as a liquid fertilizer (dissolved in water).

How can i determine how frequent i need to add fertilizer and how much i need to water?

Thanks
