I'm all over graumau5 at the moment as well as numerous grow logs. Learning is happening slowly but surely :-)
Unfortunately they dont ship outside of the US...
Don't fly away just yet! I dont have much time on my hands but if I can really save over 400$ by going DIY then i'm willing to go with that route. Although I do not have any electrical knowledge.
I've got very little knowledgle in this, although I'm a bit wary of perfect sun.
" hLEDs: Bridgelux - Hi Powered 3w LEDs " is what is written on the page of the perfect sun MINI ( I can not yet post links ).You can see it in use in this series (youtube URL ) 6cA26mTIul8
Spent a few weeks on this and still confused on what light I should buy for a 4x2 grow. My budget right now is of 800 cad ( 603 usd).
After having seen the hype all about COBs i'm torn between this light from timber grow lights "200 watt cree CXB3590 Linear framework" (not looking for DIY)...
