As some of you may know I got my first CP's in April and they're doing fairly well. Plenty of light, water, good temps and decent humidity. I use the water tray method and had quite a shock this morning...
I've done a lot of research and most places I've found say "clean the water tray every few months" to even "once or twice a year." This morning I was using my TDS meter to demonstrate to my fiancée that even a tiny bit of fertilizer increases the ppm of water by a ton! (She uses too much fertilizer to water our non-cp house plants haha). While I was making my point I dipped the TDS meter into my water tray and much to my surprise it read 170ppm!! I shrieked and yanked all the plants out, scrubbed the tray, refilled it and it now reads 1ppm.
Is this a situation that happens to you folks from time to time? How often do you guys clean your water trays?
