Thanks guys, I truly appreciate the input. I am seriously considering "the basic requirements" as I write this note. I will order the HPS light Thursday. I have decided to close up the back of the boat and use the whole room back there. Besides, when anyone walks into the boat they can see right back there -- I NEED to put in a little wall and doorway, black out the windows back there, put in some good light, ventilation, get some good soil, and I will have enough "private" space for vegging and flowering. I have found another place to get seeds, and will order on the first. I will get one of the HTG supply HPS lights, upgrade the hood, and set this floating grow in motion. I have time -- no hurries -- patience is the key -- I definately have the desire. My chihuahua "Bubba Cush" thinks I'm nuts, but what does he know -- I am the one with all the college degrees, lol. Peace people -- and thank you soooo much for the words of confidence.
