The centre on the farm in Anglesey, North Wales, runs alongside another new unit for aquaponics for water-growing salad crops such as watercress.
"Hydroponics is the buzz technique of commercial growers worldwide," said co-owner Rowena Mansfield. "The US leads the way, while vegetables imported into the UK from Spain and Holland are likely to have been grown without soil."
The unit, set up in an 18m x 6m polytunnel, was paid for with European funds and cash from Anglesey County Council, the Welsh Assembly and the farm.
Mansfield, who runs Herbs from Wales with husband Philip, hopes to form a hydroponic cooperative with a dozen or so growers to market their produce locally.
The company grows herbs using hydroponic and aquaponic methods and dry them for culinary, medicinal and aromatic purposes.
Two-day workshops are being held to introduce small commercial growers and small gardeners to hydroponic growing.They include theory, practical applications and an introduction to aquaponics.
Dates are 4-5 April, 9-10 May, 4-5 July and 5-6 September.
