Fantastic product line . Easy to use and follow food schedules. Red sun makes a huge difference when flipping to flower and bud fusion made my flowers fill out really well . I have now invested in all of the 1 gallon jugs of nutrients and out of the start box sets I had bought. For any of you that want a great box set try their 2 parts system or 3 part box system . Very good price point . On 4 plants a box set will last me 2 grows from start to finish .
