i was looking on craigslist and i found some nice floros for really cheap they are out of a reaf Fish tank they are 100,000K spectrum will these work for an indor grow???
it can be used in the last week of flowering before harvest to trigger a stress response caused by the UV light produced. this makes trichromes and essential oils "pop" just before harvest. always wear 100% UV sunglasses if you do this or risk your eyeballs getting a sunburn.
