i use the flora series or flora nova.. for ease.. i am very meticulous with my ppm readings and ph.. i have a tri meter and a seperate ec ppm that i calibrate often to check the accuracy.. follow a chart from nutrient manufacturer.. this is the most important part i belive the rest is takes care of its self.. \
yeah co2 is good if your using a co2 controller. something that monitors the ppm in tha air to 12-15oo ppm is a must.. dont trust any other method.. usually good for smaller areas;.. research co2 alot before using temps and everything change.. i dont use it in bigger grows..
In all your experience have you messed with co2 at all? What type of nutes do you use on your system? I just bought it, i didnt even hook it up yet...so I have to go pick it up at the hydro store.. I just have the system and the hydroton
yeah man i have done several runs and that is by far the best scenario for me.. my strains are very intermediate as far as yield.. in my 15 yr experience.. but i still get 3 z plants on ave.. the 2 gallon buckets dont allow for much larger trees due to the root balls size when its all said and done..
