Strong bed storage ?

I need a strong storage box that’s really low

I need to put it under a 150kg plant pot to sit on lol any ideas ?

I am holding a toy box that’s too tall that says “my stack limit is 100kg”
but I can’t find that on any box online lol

it’s to make a kinda swick cross sip hydro system

DIY, you'll have more of a sense of pride when it's finished. Sometimes DIY can be cheaper and you can build it just as you need it.

I built mine out of wood basically a frame with legs to the height I wanted for my lights I grow in a very low ceiling room

I use a 15 mill tarp fastened to the frame and sloped to the one end so all runoff collects and puddles together so I can suck it up with the shop vac.
