hi skunky,
thanks for your comments pretty useful !
Yes, I try to do some research of course, save asking every single dumb question to you guys, as helpful as you
Im in UK btw. Benn having a look at the light requirements for photosynthesis, good to know a stock CFL could carry through the first steps, enough of the components to make it happen.
Going to have a think about it, probably like many of my projects it'll end up more expensive than I wanted on day 1, but that's the learning process too. LED I think. One thing I have learnt over the years is sometimes better to splash out on the right tool for the job rather than spend thrice as much trying everything that doesn't work first...
