Hydroflex I'm living in a country that has plenty of garden stores that sell soil nutrients but when I ask them about hydroponic nutrients they have no clue to what hydroponics is. However I did have some luck today when I found a store that sells a product called hydroflex. Has anyone heard of or used this product? I'm trying to avoid ordering anything online only because the shipping cost ($200 usd) is more then the products I want to purchase. One more question, I'm very new at growing plants and Rating: 5
