Would DE have the same effect? What I find appealing about coco coir is that compressed coco brick is basically sterile (I’m buying canna coco compressed). So if I add a barrier of sand or even DE, it is basically impossible for soil dwelling pests to penetrate.

Coco grower for 18 years now, ummm be seen mostly fungus nats ...but I got one for you, I take paper towel an put around base of plant, stops gnats from coming up an stops them going down do to the fact that they have no access up or down, also weed fabric on surface...Canna Coco is the most worst coir to use IMO because I've used last two years and gnats in it the bag version not bricks...

Without it , I find the water runs right through the coco. I use the DE weekly. The play sand is sterile and the coco should be rinsed a couple times before use and keep watching the ppm diminish gradually each flush

I am also planning on multiple feedings per day. I was considering a 50/50 coco/perlite mix to prevent the coco from staying too wet.
