No, as you can see. An occasional bleached bud tip, but generally OK. I could probably turn it down and lower the frames if I had a more event canopy - that would definitely be more efficient - but I grow all different strains which grow to all different heights, so running a little more power and hanging the frames a little higher works to penetrate the different canopies. I sacrifice the odd bud tip to ensure all the buds lower down gets lots of light.
