I bought 3 of these. I needed a way to bottom water orchid seedling compots in my garage over winter. These trays are perfect for soaking a full 1020 tray with holes, that is full of pots. With orchids fresh out of flask, I prefer to water from below instead of overhead to control fungus and damping issues. These trays are perfect for that. Sides are high enough that I can soak right up to the rim of the pots if I want. These are very heavy duty trays and should last for years for this or lots of other garden uses. As soon as they are back in stock I'm ordering 5-10 more just to have around. These are sturdy enough to carry with water in them and not worry about the tray breaking or collapsing. If you want something super strong and easy to clean these are perfect.
