I have no experince in al of this,but my plant looks have no objections of this light. LEDs look pretty good quality and shines bright. about wattige i agree. its not enoght for any serious crop.
Thats my first,experimental grow. On next maybe i will look for some more serious light. I have read about it and now that normaly for good yield you need about 400w. Dont want big bills for electricity. And this lamp i got almost for free and seed is free and box is handmad. But i like this...
i grow for 1st time and my buds looks small on 4th week of flowering. i have full spectrum 210w LED . my grow box is 60x60 cm do my growlight is to weak?
