Yes, your plants will be fine. If you think they are stretching then put the light a little closer and put your hand under the light. If it burns you then it will burn your plants. (Be careful) Also, lowryders are a great plant. Hope all goes perfectly well for you.

Tomthehippie, Yours look great, and yeah cant give anymore adive, for a talled plant, move the lights up a little every now and again. Good luck bro.
