Grow Power – Standard Grow Hydroponic Nutrient Solution – a tried and tested formula for growing plants hydroponically. Our Standard Grow solution gives your plants the best possible support throughout vegetative growth stages. Standard Grow works by maximising the amount of chlorophyl produced by your plants and used in photosynthesis. This in turn ensures the greatest amount of light possible is absorbed and turned into carbohydrate within the cells of your plants guaranteeing strong and healthy growth. Switch to Standard Bloom to give the same support during flowering and fruiting.
