yup those work (6500k) (2100) but what they are trying to say is while yes the floros will work but you would need like 20 of those tubes for it to be worth it while a single HID bulb will do much more.

if it was me id just invest into a 400watt hps and grow 4 plants you will get more out of those 4 plants vs. what the tubes would do with 10
