I'm going to go ahead with this, the first thing I need to think about is the cost of how much electricity that I'll be using and how much light I will need to use, then I'd need to determine how safe the light exposure would be and what precautions I'd need to take if I'm planing on spending a lot of time with grow lamps. Also I'll be doing some research into powerful solar panels that run on minimal light that can charge batteries to where my grow lights would get there power from and also work on the best way to get maximum power from a solar panel without any energy being waisted... but for the time being I can run them from mains power until I think of a more energy saving way so the project never stops lol
