  1. Buds are getting big and yum but I have been over run by flying aphids that appeared over night it seems its so bad that 1 leafs underside was virtually black being that I'm half way through and all buds have developed now most things will kill my plant (got told that by a grower I know) would neem oil work to get rid of such an infestation and not harm the plant my biggest concern is its covered in THC absolutely covered...
  2. By the way its in a 2x2 tent indoor under 4 400s it was suggested to remove the plants spray them and spraythetent let it dry and put the plants back in
  3. Neem oil will work however your plants are pretty far into flower and I recommend not using it while flowering. As it is slightly toxic. you can try putting some sand on the top of your soil and see if that helps. Neem oil is a great preventative and works well to eradicate infestations quickly but not when your girls are flowering so far in. Get some sticky pads and some sand and allow your medium to dry out. Since gnats love wet humid environment
  4. Best to put fly ribbons up all over and some sand on top of your soil.
    I've even went as far as to run a torch across the top of my soul really quick to toast them bitches before haha.
  5. A fan should keep the little friggers off you plant....ladybugs will clean up yer problem....i usually have a few pet spiders in my tent that help alot. Diluted SM90 as a folier spray can be used up to a few weeks before harvest and using silica (silica blast) from start to end of a grow will really help your plants develop a bug resistant armour.
  6. Any one ever try a bugzapper? Common house flies run amuk where i am so i would def get one now if they are good at killing gnats too since you can get nice looking sconce style ones for indoor use these days.
  7. Actually a neem oil is completely organic and can be used up until harvest. Read the label and follow instructions.

    So neem oil says on the bottle that it's OK to smoke? Organic in no way means non toxic. I'd at least look at how long it takes to break down after all it is an oil and doesn't just disappear.

    Neem is OK to use up until harvest on stuff you can wash off but is it OK on stuff that can't be cleaned? My guess is hell no!

    Not true at all, yes it's organic, but its toxic, and has a toxic symbol on the label. Make no mistake, neem oil is toxic and if smoked I'm sure will lead to many health complications. Its not recommended to use once flowering begins, as neem is a systematic pesticide and it will be stored in the plants tissues for up to ~ two weeks. This is why we do our neem treatments early on in the life cycle to prevent the toxicity ever becoming a problem. Because it will reap the rewards of neem oil for a few weeks, while being out of the plant come flush and harvest time. Spraying breaks down quickly, but traces of toxins will be stuck all over your resin glands, I'd rather not smoke or spray my great smelling buds with shitty ass smelling neem oil
  10. Sticky pads around the surface will solve your problem fast. I had a big out break of them 4 weeks into flower too. 2 days with sticky traps and I didn't see any more flying around. I changed out the traps and haven't seen or caught any since. 
  11. Sticky pads are simply used to monitor pest levels not control them. I don't know what kind of systemic neem oils you guys are using that have toxic labels but that's no good. I would suggest using dish washer detergent and warm water if you only have access to "systemic neem oils" as you claim.

    All neem oil is a systematic pesticide....
    Doesn't matter where you buy it from, the oil still comes from pressed neem seeds, which is a natural but TOXIC pesticide. Neem is naturally systematic which just means it will be absorbed by the plant tissues, and when biting pests eat the leaf/ roots, they are then affected by the toxic neem. Liquid dish soap does nothing except mix the oil in properly with the water lol, otherwise it will float to the top and not mix with the water and will leave an oily substance on your plant

    The sticky pads will at least get rid of most flying gnats, I suggest letting the medium dry out completely and using sand as a top layer for your medium so no more larvae hatch

    I don't know if gnats are aphids but I looked at them with my loop and googled what I saw and it was flying aphids and there first stages nymphs the fan idea doesn't work the dry idea doesn't work I have 4 fans in the tent big ones they didn't even move when I was trying to vacuum them off which I only did till I destroyed 1 fan leaf lol I let them dry out and they spent 5 days in a cold dark cupboard and also a day before they went back into the tent I hit them with my spray gun with ice cold water read about it some where sprayed top of soil in half dilute neem put them back in and they are back but only on 1 plant not the other 3 in the tent any more suggestions
  14. Funny. The bright yellow sticky traps were all that I used and within days I had nothing flying around my tent. Guess they just decided to abandon my tent? go google it - it works great 
  15. They don't fly much they migrate mainly on the leaves but they are all over the place buds stems and all is there anything I can use to spray my girl with that's not gonna kill her at all but will kill the aphids or make them go away an old school grower suggested buyba bunch of marigolds and stick them in my tent they are mothers nature natural bug defence he says good idea or no?

    they are not gnats they are flying aphids which start as nymphs and then grow to an adult nymph then certain ones when food sources are looking smaller they develop wings to go to new places and heaps of them have wings they barely fly anywhere they stay under the leaves like mites but they arent mites im a novice but i know these are defintly "flying aphids" and i dont think they have larvae either the stage chart for growth on google said 3 stages which is described up top this is really stressfull everything i try isnt working and im to far in to spray most of my big fan leaves are gone.... i have 4 main colas and each has about 3 big fan leaves left a mate of mine told me marigolds will deter them from my tent and another mate was wondering if diluted citric acid would work like some lemon or lime juice in a sprayer 1 part to 10 parts water or something he said it may make them not want to be on the plants 
  17. Taken from the internet

    " Try spraying cold water on the leaves, sometimes all aphids need is a cool blast to dislodge them.
    Use commercially available biological controls or by spraying with insecticidal soap or horticultural oil.
    You can often get rid of aphids by wiping or spraying the leaves of the plant with a mild solution of water and a few drops of dishwashing detergent such as Ivory.
    Stir together 1 quart of water, 1 tsp of liquid dish soap and a pinch of cayenne pepper. Do not dilute before spraying on plants.
    In a spray bottle combine 2 parts rubbing alcohol, 5 parts water, and 1 tablespoon liquid soap.
    Organic controls include alcohol spray (isopropyl alcohol, straight or diluted), soapy emulsion (can be mixed w/alcohol), horticultural oil (read the directions) and pyrethrum spray. Soapy water/alcohol should be reapplied every 2-3 days for 2 weeks.
    You can also purchase beneficial insects, such as lady beetles and parasitic wasps, which will feed on aphids. These are usually ordered via mail-check the Internet for labs.
    Bring beneficial insects to your garden by adding plants that attract them. For example, nasturtiums are a good plant to rid your garden of aphids."
