they have stretched for the light as with halogen you cant keep it near the light as it gets hot , bin the halogen and get yourself a cfl that would be better and if you are stuck with the halogen try and get a fan inbetween the plant and light and as for your brother hide the fuckin sissors as cutting the leaves will fuck it u p and stunt its growth and halogens get very hot and are a fire danger you would be best getting some fluros one will do to start with as the halogen you are using contains mostly red spectrum and this will encourage stem growth hence the stretching so hope this helps you out but sort that brother out and stop him cutting man , best of luck ,but be carefull with that halogen if you have it in a cubourd or box it will catch fire so be carefull
