you should be fine if youre just getting a T5 set. i think youd only have to worry if you had lots of dollars racked up on your credit card from place like secret herbal growshop deluxe canabis nutrient and supply center ( i just made that up). a t5 set here or there or some nutrients everywhile arent going to send up red flags really. there are gardeners out there using the same equipment we use for thiings like tomatos and im sure they order offline. if youre still too paranoid maybe just get some cfl's from the hardware store with some clamp lights. cheaper than t5 and work just as well. best of luck!
