Can I use Baby Bio on plants grown hydroponically?
Baby Bio was not designed for use in such a system, and we would recommend Phostrogen Plant Food for this purpose. When is the best time to feed my house plants with Baby Bio? The best time to feed house plants, and indeed any plant, is when they are actively growing (i.e. when new growth can be clearly seen). For house plants this can be all-year-round. It is advisable to check the plant label for specific advice or refer to ‘The House Plant Expert’ by Dr D G Hessayon.
