use the best led's you can get (for your money)as the cheaper one's like they use in the cheap grow lights just really not that great especially if you want to grow more than 1 plant....there are also lots of site's for schematics an diagfram if you google you can also find out resister value to mach the amount you are using....got any questions just ask peeps i will help as much as i can
very nice! Well done!
