I'm sure this is not the first time something just like this has been posted. I also want to start by saying I'm not taking credit for anything shown, just sharing a helpful link. http://www.420magazine.com/forums/s...68-diy-dwc-cloning-tutorial-easy-cloning.html I built one just like this on a smaller scale. (I'm not into posting pictures) but It works great, they almost instantly respond and take off. I have been growing in dirt for many years, but just started playing with hydro and found this great link. The beauty is its extremely cost efficient and you can make them in all shapes and sizes.
