hello greenthumb,
I havent gotten any clogged emitters, did have them dripping at about 20 drips per minute but i would find that they would slow down but they never completely stopped dripping. when that happened i would just open the emitter up to a full stream and then back it down to 20 dpm. the
pump that I bought had a halfway decent filter but i added a peice of the wifes nylon stocking to it and it seems to work quit well, I just had to rinse it at every
nutrient change which was about every two weeks. I havent been using that system for about 2 months as the plants grew out of it and into a bucket wicking system where they have really eploded lots of tomatos and peppers.
thanks capt38.
