No way ; viruses are not like bacteria - they can't just float about...
They can only , but only, be transferred from inside one cell to the inside of another - by an unsterilised cutting implement, or by a sap-sucking insect for example - and there is no more risk in hydroculture than in any other system.
As for virus testing - its too expensive. If I I am sure a plant is virused I destroy it. If I think its virused, I watch it carefully ; and every time I find one like that I try a bit harder about sterilising my cutting tools. As to sap-suckers - scale etc., then obviously I try to keep them down and preferably out !
Lovely set up, your plants looks so healthy. Thanks for sharing I love to see how others grow
