leds just don't have the power to grow big buds

I love my led growing lights. I switched out my 600w hid light for a hydrogrow 126x pro which was 899.99. The price is pretty high but after seeing the results that price didnt matter. I grow in a space that gets pretty warm and when i made the change the heat was no longer a facter. I also could see my elc bill cut in half right away which is nice. I continued to search for led grow lights and found a led light company that sells similar grow lights. the Lights were a lil cheaper and had a higher output. I bought there 210w pro for 699.99 with the same warranty. The Lights work wonderful and i plan on gettin a few more after my harvest. that site is optic-lights.com. I will be posting pics of the grow shortly
