I found the perfect shelves to add to the far end of the greenhouse. It's actually a mini greenhouse and was on sale for $25. I bought 2 and they fit great. Whole bunch more space for plants.
These dont last long, the plastic joins snap. Hope your plants aren't on them when they do. I had to get my partner (who welds) to weld me up some to repace the ones i got from ebay the same as yours.
