The following list of popular plant food manufacturers is in alphabetical order. We do not wish to become drawn into the argument about which of these is “the best”. The best nutrient for you is the one which gives you the best results and that you are comfortable using. Some of the nutrients are single bottle and some are multiple bottle formulae. We recommend that you start with something simple to use and then, as you become more adept and your confidence grows, graduate to the more complicated systems. You may well find that your original choice suits you better and so will go back to it.
