Another question: Does a fluorescent have an expiry date?

I already have enough fluorescent at home but I had them for 5 years now with little to no usage.

Thanks

Also, is it possible to spot female with a florescent tubes under a 12/12 light cycle So I can clone the females ? I dont feel like buying a 400 W for 3 weeks of usage only to spot female since I will get 3 1000W HPS for the flowering in 1 to 2 month. Thank Rating: 5
