BTW b00m, another tip for pests...
If an epidemic starts quick and gets out of control, grab a bottle of CO2 (beer gas from BOC or Liquidair). Turn off your fans when lights are out and temps permit and just gas the little fuckers. Leave the fans off and gas in the room for a good 6-12 hours. CO2 is heavier than air and generally stays inside mainly closed spaces as long as a fan doesn't circulate. Plants love CO2, little insects choke. It's saved me twice from hardcore pest invasion.
Turn all lights and fans off and gas entire room with a large volume of CO2. If you can hardly breath in there than you've got the right volume of gas. Leave for 6-12 hours depending on if you are in veg or flower. Repeat until you're bug free. Use with very diluted foliar spray of need oil or similar. Perhaps consider using the neem oil in your reservoir as per ozzieAI's instructions.
That should definitely take care of those little nasties. it's organic and non toxic too. Yay.
Peace out bro!!!
btw... If you know anyone who works in a pub or bottleshop they might lend you a food grade CO2 or cellarmix bottle. Otherwise go to BOC or Liquideair.
