With the construction and installation of the slatted shelf, the inter-greenhouse storage facility is now operational.
The woodwork is not going to be mistaken for a Hepplewhite item, but it will serve the purpose and was very nearly 'free' - in the sense that the only "first use items" in the project were the four aluminium nuts and bolts holding the angles in place and a tablespoon of fence paint. The wood, the woodscrews and the nails were all salvaged from previous structures and the aluminium is off-cuts from earlier greenhouse modifications.
There are rails on three sides, to reduce the likelihood of items being shoved into the glass or off the back.
The watering can seen there is an interesting item, particularly for those with larger houseplants - the water flow is controlled by the push-button* on the handle, allowing the can to be tilted, when approaching the plant, without water sloshing out in the wrong place. Also handy in the greenhouse, of course.
* Just visible in the picture - Nu-Can is the trade name, should anybody be desperate for one.
