Hi,

If your floros are between 5000K and 6500K in color temperature it will be god for vegetative phase wich is ending between day 25 & 35.. depending wich strain your growing. Usually i end the veg phase at around day 30 and then i switch my light to a HPS one for blooming the ladies. You need a stronger light for flowering with lower spectrum light like a hps will provide.

Good luck & Happy Harrvest!
