I tried coco coir for the first time and I just love how I can plant seeds directly in it like soil. Especially for plants like cilantro where you need a lot of them.
But I am surprised how long the coco coir stays wet. Currently only needs to be flooded once per week. With the expanded clay, I have to flood my trays once or twice per day!
I was just wondering if I should wait for it to start drying out like I do now, or if it would be beneficial to flood it more often. It seems like with each flood cycle it also forces new air into the medium. On the other hand, it seems like it could be too wet and cause root rot. I appreciate any insight.
Note I added clay pellets to help it drain better but they just floated to the top! I think next time I will lay down a layer of gravel or clay pellets but have a screen on top to keep them from floating to the surface, then cover with coco coir.

That’s the benefit of coir, it can hold a *disgusting* amount of moisture without turning into a solid brick of anaerobia. But that’s also why you should be careful with it.
Youre looking to mix perlite in with the cococoir. Not clay pebbles. A typical mix is 75/25 coco to perlite.
