Now the answer to this question depends on a number of factors. You should know how many plants you want to grow and how much of a space do you have with yourself. You must also know your expertise level and get a hydroponic starter kit based on your skills! Some of them are smart devices which offer you insights on when to provide nutrients and can also handle switching the light on and off by themselves. There are others which don’t have any such features and need your attention all the time. Some grow kits come with a warranty period of just a few months while others offer upto a few years. Last but not the least, the price is a major factor that comes into play too! All of these things need to be kept in mind before you finally decide which is the best hydroponic starter kit for you!
