When your plant reaches the peak of it's flowering phase it naturally will start to rapidly decline. The amount you can harvest from your hydroponically grown plant is determined by the particular genetics of your specific strain and conditions of the grow environment during it's life cycle. Sometimes for example the particular strain may be genetically made only to have small flowers and a short flowering phase or you may have noticed during the plants flowering phase that it isnt flowering as much as you expected from your particular strain. In fact, even if you are sure you have gotten everything right in the grow environment and have chosen a large flowering strain and even used bloom fertilizer to increase your potential harvest, the natural cycle of any plant is to rapidly decline as soon as it reaches its peak of flowering. If your plant is falling short of the yeild you expected, there are so many factors involved that it may be difficult to determine what was the exact cause especially so late in the plant's life cycle. By using Overdrive in the last third of your plants life cycle, you will greatly increase your plants harvest. It contains unique ingredients that have been proven to defy the natural decline of your plants when they reach their natural peak of flowering. In fact, Advanced Nutrients are so sure about the capabilities of Overdrive that they 100% guarantee you will get a rewarding harvest from your plants. Overdrive reinvigorates the bloom phase with its unique concoction of organic materials, nutrients and vitamins that will give your plants an important increase in the terpenoids, resins, essential oils, aromatics and potency that are desirable to increase the market value of your harvest. The scientists at Advanced Nutrients have found that the unique ingredients contained in Overdrive are even better than other Advanced Nutrient products such as their own Big Bud for example, which is impressive because Big Bud is a bloom booster that is added earlier in the life cycle of the plant than Overdrive is. Overdrive is added in the last few weeks (the last third) of a plants life cycle and is 100% guaranteed to boost the harvestable crop from your plants. By using this product you also dont have to worry about it altering the pH of your grow because if used as directed it will have no effect on the pH of your plant.
