Cymbidiums - untouched by human hand
Further along the bench with tthe S/H I have my cymbidiums - about 200 pots of them. They were all repotted , with division of the larger plants, so that all most are probably flowering size if they grow well, and few are large flowering sioxze. I simply cannot lift a large cymbidium nowadays ( my age , no doubt ) and even an 8 inch or 10 inch pot, when well watered is more than I want to heave about ; at least I don't mind one, but doing a hundred... no way. So, automatic watering - which brings me to the start of my techie stuff. But first here is a pic of what some of them look like.
The new leaves are good - reach the glass above them, in some cases, and the headroom is never less than a metre often 1.5.
Water ( and nutrients) is stored under the central bench, in a series ( about 6 or 7) 250 litre tanks.
One of them for the cymbidiums contains an immersed pump, switched on for about an hour, twice a day. the water is fed to a computer
which opens the supply to a distributor
The distributor has 6 connections each for a separate drip line. I am using 4 at the moment. Each time the water supply is on, it shunts the connection to the next of the six. So in six operations of the pump, each line gets the water once. Obviously all the settings, like how many times per day, or week, and how long for each pump operation, can be changed on the computer.
