I used a Phototron for about 10+ years while my kids were young and I had no room for a real grow. I only flowered the plants once in it. It took alot of time and the buds were small although asskicking. What I did with the other grows was to just smoke the growing shoots from female plants. The shoots were just as potent as what I could buy however nothing beats the taste of real bud. It's quite time consumming because you need to prune contantly and watering is a chore. You grow 6 plants which become little bushes, very thick little bushes. There's a whole methodoligy for pruning. I would prune enough every day for about 4-5 joints and let it dry overnight on top of the machine. I was almost never out of pot.
I would suggest going to Pyraponic Industries -- Still the Original. Still the Best. and ordering the kit which contains the spagnum moss and nutrients. I would also order 3 extra bottle of nutrient which will last you through one grow, about 6-8 months. It will also include a full set of instructions.
Now that I have a real grow room I would never go back but still use the phototron for germination and occasionally keep a mother in there. They do grow like crazy in there.
One thing is to make sure you use the highest quality Indica that you can find for best results.
Good luck
