Solar Green Power from Buddha's Tree uses silicic acid to boost your plant's growth. Silicic acid can improve your plant's immune system (so it can resist diseases and pests), boost CO2 absorption, enhance nutrient uptake and reduce the amount of water lost through leaves. If strong branches and huge stems are what you're looking for, you want a silica product like this to improve the structure of your plants and enhance photosynthesis, by assisting with chlorophyll production, allowing your plants to maximise the energy they gain from light, water and CO2.
