Can I use the coco if it has dried out.

yes just resoak it. might be slow to take it in but it will work. give it to a day or two to soak it all up

hey 👋 Of course, coco coir is neutral, and as long as the fibers aren’t shredded you can reuse it by rehydrating it. Just remember to check that no mold has formed in any potential pocket of moisture during storage, and that no pests have made a nest in it (unlikely if it was well dried). If that’s the case, spread the coco coir on a baking tray and put it in the oven at 80°C for 1 to 2 hours depending on the quantity

Just rehydrate it slowly mate and rebuff it, its totally fine to reuse. Good luck
