Think that's too far away to start clones on, 11"? They would grow at least another inch or two over the next week I should think closing the distance even further, then another inch or two the second week, correct, no?
T5HO has its best performance about 18 inches down, after that the photon density is poor. I would recommend running the tubes vertically if possible, without a reflector, surround the tube with plants.

As for 11 inches being too far, nah, you'll be okay. I have my LED light almost 3 feet above my mothers.

As for growth, that's all dependent upon the care you give the plants, and of course the light. They should grow rather well, and quite rapidly if you're doing hydroponics. In soil, they'll be a little slower, but they will still grow nicely.
