So, my white flies came back. It wasnt a big problem last time, but now my girls are about 2 weeks into flower and they have shown up.

They are in a grow cab and I just want to ask all of you, what is a good, fast and easy way to get rid of them. I appreciate any advice :).

There is no fast and easy way to get rid of them. They are the hardest bug to kill.
White flies lay there eggs on the underside of the leaves near the top of the plant.
Get some SM-90, use 5 parts water 1 part SM-90 in a spray bottle.
Spray the tops and bottoms of the leaves over the entire plant. Soak all parts real good.
SM-90 will not hurt your buds. I just sprayed mine last night and they were not hurt.
Space treatments out to every three days and then spray every week after that right up to harvest if needed.
It is non toxic to humans and animals, also makes your plants grow faster. Smells good too.

White flies are woous compared to spider mites. Try pyrethrum bombs for medium and large grows. Sm-90, soap and water, neem ect, soap oil and water ect. None of these should hurt early in flower.

What about thrips? I just found something better for all these bugs, Spinosad,

These things are like my mortal enemy. Dr. doom will knock down the population and it's fairly cheap. Attain tr is works real well but it is pricey. Azamax works well too. I haven't tried neem yet, so no comment there. No matter what route you choose, you have to you have to keep up on the treatments to be effective.

I have seen quite a few whiteflys as well, used a bomber and that helped a bit, but now theyre back in full force. As they actually harmful to the plant? Neem oil isnt putting a dent in the either....

Yes, they are bad for the plants. They feed off the underside of the plant leaves, in high populations I've seen them get on the buds. When you harvest you'll think you got some good sticky buds, but it's actually the residue/sap the whiteflies produce.

That and anytime a plant has to fight an infestation it will put more of it's energy into that and not flowering.

Did you foliar spray of soil drench with the neem? If you did the soil drench it will take a few weeks to be effective.

hmmm.. I just thought they were annoying little pests.

I'm currently using a larvae killer 10-20 drops for the 40 gal reservoir, and using the foliar spray, soil drench wouldnt work for me.
