I'm not rightly sure what happened. I noticed the shelves were leaning a little backwards the other day but then seemed stable enough when I moved them. These are the large plastic ones you get at Lowes that are supposed to hold a lot of weight on each shelf. What I had intended to do was get my wife to help me put a couple of standard bricks under the back to level them out but here the old adage comes to light 'never put off until tomorrow what you should do today' or something like that. Anyway, yesterday was 'feed orchids day' and I also refilled the humidity trays. I guess the combination of the weight of the wet orchids and the newly filled trays is all it took to tip them over. At least I've got plenty of new orchid bark to repot them all with. I think when I get the other greenhouse put together I'm going to get a couple of long tables and move the orchids onto them instead of leaving on the shelves where they are now. But, as they say 'there's no use crying over spilled orchids' just chin up and move on. I'm sure they'll be OK, they are really doing good too, all are getting new leaves. They look a lot better than they did when I 'rescued' them from Walmart.
So, lesson learned. Always make sure your shelves are stable before putting a lot of weight on them.
