I've gone potty but I now have a partial treatment

...and that's how New York City was built - vertically. It works.

Be careful to keep those pots without labels seperate !

I like my 2 x 5 tier plastic minigreenhouses . Just the right height for Auriculas. Makes the best use of the shade space.

Andrew have used Galvanised steel tray sections for many years and work well, I can add one constructive comment and that is to stand your pots on fine grit or course sand ,reason it is almost impossible to have all the trays 100% level so when watered some pots end up standing in water the grit will take up the surpass with out water-logging

Looking more like a nursery every day, Andrew.
I think my OH would gib at staging under the car port, wouldn't be able to open the car door. That's good advice from Bjs.

Thanks Brian. I will get some more gravel to use on the shelves.

I use shelving like that in my greenhouses, then in the summer I move them outside to make room for my Tomato's, however Andrew, I think you 'll soon fill the patio up again, your passion for your plants will spur you on because you have some space, lol.......

I agree with Lincslass.......enjoy the space for the short time you have it.

Hear. Hear You could always have a roof garden! :O)

I had to laugh when I saw your potty disease as it reflects my garden but yours is much tidier. I have been too busy to prick out some of my pots of seedlings. Keeping the seed pots watered is a full time job on its own. That is an excellent tip Bjs.

Looks very professional!

Excellent idea Andrew......enjoy while you can!!
