turf scrubber, not working (at least nothing growing in 8 weeks)

[KevinK]

regarding the spray bar, that is what I thought as well, but when I remove the LED's on the other side, I can clearly se the water hitting the mesh, and go down, not threw the mesh.

I also did made the mesh call it fluffy by going over it with the beld sander and a scraping belt on it (one that has particles as big as 2 mm) this is however one of the points I keep wondering, if I did it enough, it did seem fluffy and riped appart when I rinsed all the plastick dust off

next week it is running for 8 weeks,

I have in mind to wayt to week 12 to 14, before changing some things on it, unless somone finds something important that is off, than I will correct it derectly
