What time to spray Pyrethrins?

[GrowInTheDark]

Hi I have a bit of a pest problem, so i bought go green botanics plant spray, for mites and thrips. I am 12 days into flowering, and i was wondering if it was best to apply it when i first turn the lights on, or before i turn them off? They have 4 hours of light left today. Would it be beneficial to just give it to them right away or wait?

You never want to spray when lights are on... The wet leaves will burn... Spray just when lights are going out and keep good air flow... Should keep a fan going to keep the air moving throughout the plants... Just went through a Thrip problem myself... Little bastards are hard to get rid of completely! When you think they are gone KEEP GOING! From personal experience stay on top of it for several weeks to be absolutely sure!!! Won't hurt your girls... Happy Growing!
