HGV plant nutrients work in any growing media! Over the last 29 years, we have used and tested HGV plant nutrients in every growing medium we could find. NFT, DWC, flood and drain systems, rock wool, coir(coconut), many different “soilless” mixes, and even soil. So far, we have not found a media that HGV nutrients have not performed exceptionally well. We will happily offer growing advice on any media that you might currently be using or plan to use in the future. Pictured to the left are tomatoes growing in rockwool and coir, and lettuce and melons in NFT trays.
