Depends on the results you want to get. Four plants in a 4x4 area indicates growing fairly large plants. LEDs don't have much light penertration, especially 1w diodes of dubious origin. I personally would not buy chinese LED crap but that is just my opinion.

Over one 4'x4' aero/fog tray I use 2- TI ProBlooms (real LED grow lights) that are 330w each for a total of 660watts, and I even use a light rail to move the lights back and forth abt 2'. Helps with changing the of the light's "angle of attack", plus I grow SOG, meaning small single cola plants that finish at less then 18" tall. (one tray equals 138 plants) Acually my "fogfognugen" system uses 2- 4'x'4' trays together for a 4'x8' area and has 4 TI ProBooms for a total of 1320 watts of really good LEDs. (equal or better results then 2- 1K HPS)

I believe that Weezard was refering to that long cut & paste of "specs" tho it goes into what light a plant needs I didn't see what the lights you proposed has for light wavelenghts. PLUS it looks like a giant advertisement for HTG, you are trying to slip in here for free. Looked to me like what the young folks call "spam".


Good luck pushing crap on the unsuspecting. It's these types of lights that have given LEDs a bad reputation for growing.


High Headshake, didn't see you there while I was slowly typing my responce.
