If what you have is 2 26 watt leds its not enuf, each of mine pull 325 watts from the wall, 1 of them will cover 3x3 (feet) in flower.
Adding lights may help, watch the heat. Will they be movable if the plants grow to close? Also watch sales of better LEDs.

When is comes to light, more is better so long as the plants are not getting toasted by it.

Go for it and let us know the results, as said watch the heat.

I will concur with the hydro master. You would be better off with a single source light for a 4x4. 300 watts is what I would be shooting for minimum with newer diodes. I get away in a 3 x 5 footprint with the samsung 301 diodes but it's on a strip light. Supplemental just takes up room.

Too much money for old tech. Check out this guy does extensive reviews on many name brand lights. My Mars hydro sp3000 can be had for 350$ usd.

I went with the SF 4000 for a main light. Happy with the results. Tests show it to be a bit more efficient with the electric bill.

Man that's expensive where you live. For the money I would go with Ckbrew suggestion. Spider farmer has good reviews.
