bwanabud,
If you read the add closely, they even offer different color temperature tubes and the reflector is made out of the reflectorized aluminum that the grow lights use, so I see no reason why they shouldn't work just fine.
Call their 800 number and talk to them about what color lamps come with them and what are available. Also ask about cords unless you have the skills to install cords into the fixtures. Also, ask about the lumen output if that is an issue for you. I spoke to them just now and these light fixtures are designed to be installed 17' in the air so will probably have a narrower foot print than the normal grow lights, but I've been using high bay (17' mounting height) MH & HPS lights with the original reflectors and I haven't noticed any reduced coverage area problems, so I personally don't think it would be a problem, but am unsure.
Let us know what you find out.
Great smoking.
