Binford, is there a reason that you need to grow the plants in containers? or could you put them directly in the ground in your hoophouse? (For that matter, Jim/MoonShadows, why do you use containers for growing in your greenhouse?
)
As far as the shelving units - those are really nice sturdy shelves for the price, I have two in my greenhouse that I use for storing stuff on (since 2017 and no problems yet with the plastic deteriorating or anything), plus we have a couple in the garage.
