Yuccah

While I'm not entirely certain about the necessity of a wetting agent in Coco, I found B.A.C. Yuccah to be quite helpful. My plants were relatively large and bushy (about 45 cm) in their somewhat small containers (8L), and even with watering the coco to achieve a good 20% runoff twice daily, the medium sometimes tended to dry out more than it should. Using Yuccah seemed to assist in maintaining the medium's moisture level more effectively, which is crucial for coco-based growing

I was a little sceptical at first, but this product does improve the soil structure. No more overwatering issues or compact soil after starting with this supplement.
