Well, this is just the week growchick destroys all her plants, I guess.
Last night, just before bed, I went to check on things, as I'm prone to doing.
One of the 12 inch floor tiles that I keep in this window above the garden, fell out. No clue why. The window was open behind the tiles, so it might have been some wind (except the tile that fell was over the closed part of the window *shrug*) I've shut the window, now.
When the tile fell out of the window, naturally, it fell right on top of a plant. It took off about a third of the plant on its way down, and then, when it hit the hose feeding that plant's bucket, it sheared the hose clean in two. So, after spending weeks getting the PPM and pH just exactly right in that reservoir, about 8 gallons of perfect nute solution pumped out into my carpet. Yay.
I need to go check the PPM and pH in both reservoirs this morning, but I'm afraid to. Ha.
