I am presently using my Power Grower for my first hydro grow (lots of soil grows in the past) ... all I did , was READ all I could before starting a plant in it ... just about everything you can think to ask, is already answered in this Forum ... do your research, you'll have good results ... there are some very skilled hydro growers in here, happy to help us, but please READ all you can before posting questions ... pic is mine, after 11 days in flowering mode ... good growing ! :jointsmile:
