Selecting what nutrients to use can be mind boggling some experienced growers will have there own recipes others will stick to one brand and follow the feed chart. Most brands you see will have base nutrients which have all the necessary NPK (Nitrogen,Phosphorus,Potassium) you need to grow plants. Then Brands also have Additives which will boost your plants in different areas i.e. root stimulant will give you healthier roots and help you produce new roots quicker, bloom stimulators will help with production of your flowers and so on, you will find many additives that do many things.
We have placed all our nutrients into two sections base nutrients and additive nutrients If there is a brand you do not see on our site please don't hesitate to contact us and we will do our best to get it in for you.
