haha nice pic. Things are sounding like they are coming together you should take some pics of everything beore you put it together. not to post but just for you. it is pretty crazy when you look back on things like tht after you get a few harvests Also you said you got a tds pen but did you get ph pen? you can find one cheap aswell and it will make a huge difference. I also went with the cheaper pens and wish i hadnt. I have to calibrate them constantly because they start to give false readings. I would also like to get a good tester but they are very expensive and who knows if they will be any more reliable. keep it up bro! GL
