I started window farming last Christmas and things look really promising so far (meaning, I haven’t killed anything yet). Just wondering, how do you clean the insides of the tubes you’re using to deliver the nutrients? For some reason, mine has the tendency to build up “gunk” (for lack of a better term) and I find it annoying. The water system still pumps water just fine, but I’m afraid that it will eventually get so dirty that it would just clog the passage way.
What cleaning methods and products are you using? Any advice would be greatly appreciated!
