No it’s not too heavy.
It has drainage.
The Unearthed 16 in. Dia Fiberglass Planter is sold as a singular unit for 44.98.
Thank you for asking about this particular fiberglass planter. Its measurements are 16" length x 16" width x 11" height.
I did not find one. Had to purchase a clear, generic one.
I wish i could answer the question better. I had mine out all winter but i did not get anything planted in it yet. The problem isn't the pot. If something is planted in it and the water in the soil freezes it could put pressure on it. I have a large clay pot that stays out all winter with soil in it and it is fine. (so far) It gets to the teens at times here on the mountain top. I wish i could tell you more but not till next spring. If the plug is out of the bottom and it drains it could be just fine.
