Not to much of a change this week General hydroponics plant is at 8in. technaflora is about 81/2in. I am liking the technaflora nutrients a lot better than the General hydroponics as you can see that plant looks a bit better. Have kept the PH issues straight this week and have also noticed that the technaflora isn't having the PH fluctuation issues the other has had. Thinking of going to 12/12 this weekend.
