Thank you!!
It's heavy, especially with the bottom basin full of wet lava rock. I would guess 150 kg or a little over 300 lbs. We don't lift it by hand. I have a hydraulic scissor lift cart, and we built a special stand on wheels for it, with space for the cart in the centre. So we use the cart to lift it from its ledge on my dining room wall (after removing the screws holding it against the wall), roll it just far enough away to place the wheeled stand behind it, and drop it gently onto the stand.
Two strong guys (my husband and a helper) need to keep the wall balanced while it is moved. I usually operate the scissor lift cart.
We always need to rent a cube van to move it to and from a show. The ramp into the truck is indispensable. In this cold weather, we wrapped the plants in two 40-ft (13 m) rolls of thin sheet foam, about 5 layers thick. Total exposure to -20C temps was less than 1 minute each time, to and from the truck. The truck was above 0 inside.
