Avid spray. Toxic. Use a p100 oil based respirator (home depot) or you'll poison your lungs. I wear goggles and gloves. Check out amazon or google to read warnings on Avid. Spray every 3 days, 3 times, when lights are off. DONT spray for a month before harvest because toxins accumulate in leaves and buds and you'll poison whoever partakes. Otherwise use Azamax or Neem oil with detergent. Less toxic, less effective, but i think it will get you through till harvest. Every 2 days at first. Lights off.
