Hello! our 1 week old autoflower got already some spider mites I guess (small yellow spinning creatures) and fungus gnats. We gave her just 0.1 lt water 2 days ago with root juice. She is in bio bizz all mix soil. Any idea if using neem oil would help getting rid of them?

I would go with one part hydrogen peroxide to six parts water as a foliar spray first before going to Neem oil or anything stronger. You can use this spray twice a week on the soil/ in the soil, and over the canopy. This absolutely helps for early infestation.

Spider mites, aphids, whiteflies and thrips can all be done away with by using either Dr. Zymes Eliminator or some Spinosad. Both are organic and can be used throughout the whole grow as needed. They will kill all stages of the insect - adult, larvae and eggs. Dr. Zymes has an added benefit in that it is also a fungicide and so can be used to battle fungus - but not fungus gnats. For them, use some Mosquito Bits that you soak in some water and then use that water for your plants. Fungus gnats live in wet soil so if you're having a problem with them, it says to me you're overwatering your ladies. Good luck...

"Bti" will take care of the gnats. mites will need soem sort of spray and other measures... predatory bugs are an option too. products that use pyrethrines kill on contact for mites and probably the gnats too. mites you may need multiple applications.. .the bti bits you top dress every 14-21 days and it'll take about 3 weeks to clear up the gnats if they are bad, now. you can use bti pre-emptively... if your soil/substrate seller stores it outside, i'd acutally recommend always using it. I use it to start every grow, and only if i don't see any hints of gnats i cease using it. it is 99% effective.. you'll still see 1-2 gnats at a time in a room full of 12 pots if the soil came with some bti will kill the larvea in substrate. sticky traps kill adults... kill multiple stages of life, if possible to speed up process. spiders lay eggs on teh leaves, i believe? as well as elsewhere.. .so, spray under leaves, into each nook and cranny... there are other kill on contact sprays.. just google the active ingredient and read up on it.. including pyrethrines... and .edu domain is usually a good source.. stay away from anyone selling stuff... they are compromised and not qualified -- http://npic.orst.edu/factsheets/pyrethrins.html -- a good example. diatamaceous earth (DE) is another options.. insects must physically walk over it to be effective, and it must be dry to be effective. dusting around grow area can help reduce crawling bugs, but won't do much for things that fly. again, if it is wet, it is useless... o not use "pool DE" .. only use foodgrade DE. with any spray, look for a concetrated bottle that you mix up... it's a 500% or more price difference, often. e.g. look at souther ag concentrated pyrethrin vs any pre-diluted bottle. same with neem and others. Don't be afriad to use more than one thing, but make sure you aren't using a bunch of things that all cause damage to same parts of plant... 1 alone is no problem but you start spraying 2-3 different things the plant may not tolerate it. diversity of methods attacking different aspects are a good thing if the plant can handle it.

Spider Mites can be in your space or come with your soil... infected is infected There are 2 possibilities as she is only 11 days old. Option 1. Start again and clean everything really well with bleach. Buy soil from a well-known cannabis brand. They pay extra attention to insects. Option 2. Buy predatory insects to feed the spider mites. Thoroughly clean the area before and after 2 weeks. Since your space is contaminated it can come back. Both with option 1 and 2. Option 1 is the safest, but you may also be able to add predatory insects to the new plants and soil. Also buy some neem oil to add to your leaves in the growing phase. Still, option 2 is a good learning lesson to see how you can fight them naturally. But then there is certainly a chance that things will go wrong. But mistakes make you a better grower in the end.
