I once saw on a Fernly Whitinstal show, that you can grow you salad crops in gutting.
Bingo, I bought some and screwed it to both our Green house staging, and low and behold, you do not have to bend down for the crops!
Instead of glueing in the ends, I pop riveted them, so that we have some drainage.
Why not give it a go.
ALSO
As I now have to work (regretably) shifts I have installed a series of plastic pipes, and secured some hoselock sprinkler nozzels. All I have to do now is plumb in a few more outside taps, and fit timers. Then the 2 greenhouses, the veg plot and the hanging baskets on the front, will be watered without me being there! Initially i tried 22 mm, but I would recommend 15 mm, as your fixed pipe work. I recommend that you spend the money and buy the proper push fittings, as it will save you playing with silicone sealant. Just remember your mains pressure, will dictate how many nozzels to have. I have 7 in the 6 x 8, and 8 in the 10 x 6 which feeds 3 more out side. I am going to have to replace some 22 mm to ensure that the ridge sprinkler works, and covers its salad tray.
The front ring main, is from the local tool shop, but Aldi sell the same item with thier own logo's for the same £5.99. Just route from your feed point and cut/insert the drip fittings, and you can descretely water you baskets/tubs.
In the veg plot, I have poundland sprinkler hose, cut and joined using copper pipe/hose pipe lenghts, and jubillee clips, to get it where you want to go.
So there you have it, watering/salad growing made easy.
Just remember outside taps require a non return valve, to eliminate syphoning into the household water system
