For pest control. I have heard of this .For other reasons of use mentioned .I have not.
Does not mean other reasons are not correct. But pest control for sure.
I don't think DE adds any nutes, but it does work for pests (as does cinnamon). Don't expect to much on the light reflection...
Ok thanks for the feedback dudes!

I always thought DE was high in silica as well as trace minerals but I could be wrong on that.
For keeping soil temps down I’ll just stick with mounting the netting a few inches above the soil (while making sure the plants still receive full light) as @Arthur suggested.
Will post some pics once it’s done if others want to copy the setup in case they’re in a similar climate.
