Greenhouse staging

I was just wondering what everyone used for greenhouse staging? Is it worth buying specific staging or what could be used in its place?

I was thinking of having staging down one side and using the other side for growing.

thanks

I have some proper aluminium staging in a couple of the greenhouses but also use the 'blowaway' mini greenhouses and the shelving that that company (?) makes. These can then easily be lifted outside for hardening off, which leaves ground space inside for other things.

Pick up cheap blow a ways at the end of season in Wilko then early season you have a grow house in the greenhouse for extra frost protection, each layer is worth two weeks in the sowing schedule.

Stage 1) Staging in our greenhouse follows some sort of rotation, in that we have just one side wall with removeable staging (cedar) in the winter. There are water trays along the end and sides of the rest of the space.

Stage 2) In spring, we take out the overwintering shrubs like fuchsias, and move them into a temporary blowaway fixed to the back. Then we assemble four x four shelf sets of black collapsible shelving (stored in the roof or the woodshed after a good wash down each year) and stand them in the greenhouse spaces, along all the walls and at the end, for all the trays of seedlings etc.

Stage 3) Finally, in summer, we take out all the staging, (except for a small work area in one corner, store the black stuff and the blowaway, and stick the cedar 'winter' staging outside at the back of the greenhouse, on which we grow carrots etc in buckets, high up. Then we have the trays on the ground for tomatoes, peppers and cucumbers.

(Did you get all that..;0) We've just completed stage 2...

I've struck lucky, cos my new 8 x 8 greenhouse got delivered yesterday and came with free aluminium staging, enough for one side
