I have seen a small problem. This is my first problem with the project. I have to go and find some type of timer for my light because if I do not I will dry out and fry the top of my plant. I have got the timer off of another light and rewired the wires so that I could use it on my lights. I have a timer with 2 hours, 4 hours, and 8 hours with different modes of light rays.
