First time grower...Blue Cheese?!

Decided to give it a shot and do my first grow. I'm growing 'blue cheese' indoors in a tent from cuttings. So far, so good (I think). They have been in 5 days now and got slightly taller. They are having 16 hours of light and 8 hours off, as advised by the hydroponics shop I purchased all the equipment from.
Does anybody have any advice on tips on getting the best out of my grow?
Thanks :)
