Well Capt...I would like to make a suggestion....Keep the hydro equipment for future growz. But, you may want to get a grow or 2 under your belt. For that purpose soil is IMHO going to allow you to learn something about cultivation and to get a successful result. Soil is very forgiving and easier to deal with for an absolute new grower. In soil, if your gurlz develop issues it gives time, even a few days, to diagnose and correct. In a hydro environment the same issue can kill a plant in hours.
Now, I stand behind what I said about new growerz being successful with hydro and soil less mediums. But, it seems as if you are wanting a plug and play type of grow...and that just isn't going to happen especially in hydro (unless you spend some serious cash and get a BC northern lights box and even then). There is a lot to learn about growing as a whole. As indoor growerz we are responsible to create an environment conducive to growing a healthy plant...it is essential that we learn how to properly care for a plant and give it what it needs and when it needs it. There is a lot of education required to get a grow dialed in and not kill plants left and right. Hydro growerz say they produce better yielding, better tasting, quicker growing plants than they did/do in soil. I do not dispute the truth in that.
But, if I had a new grower ask me what they should go with their first time out I would always say soil.
But, it seems you are determined to do the hydro thing and I wish you luck. I think you should perhaps start by reading and posting your questions in the Hydro forum...
