Hey everyone, I am a first timer and are currently in the seventh week of growing my AK47 in a bubbleponics 6 planter. I have been consistently taking pictures every couples days from the start and are more and more amazed at what is being grown. They are in a closet surrounded by tinfoil, I have changed the water about every two weeks and have been adding nutrients given to me by Stealth Hydroponics (where I bought my system). It seems to me that everything is going well so far but I wanted to open it up to people who might have a little more growing experience. Please feel free to critique the methods used, or simply suggest a better way to do something. Anything and everything is appreciated. Thanks! Question- Is it bad for roots to be submerged in water?
