now my grow room is infested with some type of little fly or nat. are these killing my plants or atleast causing more problems. there EVERY WHERE in the soil and on the ground. on the buds.

i have now switched to pro mix and got rid of the rusty wieght by the way. please comment or help me out in any way thanks guys + rep oh and sorry for a long/ short dicription so if you got quetions plz ask

the fly is fungus gnats, you can get fly strips to catch them, you can water with sm90 added. or you can use gnatrol from the growstore. or even use mesquito dunks to kill the gnats. they eat your roots and lay larva in the roots and the larva eat your roots. the gnats make it easier for your plants to become infected with all sorts of problems.

are they harming my plants or is it something i shouldnt worry about but still get rid of???

yes the gnats will harm your plants until they die, you need to handle the problem asap

alright thanks

not sure where your info is from, but if they are indeed fungus gnats, they won't harm most plants.

The gnats themselves live for 24-48 hours, and are simply a nuisance. They will get stuck to your buds mostly, so if the idea of smoking a desiccated insect with virtually no mass isn't appealing to you, then you might want to get rid of them.
Their larva (the part most people are concerned about) live in the top 1/4cm or so of your substrate (soil usually). In this small area, they will eat decomposing matter, and in the absence of decomposing matter, like peat, will munch on some roots. However, you have to keep in mind that this is in a very limited area at the top, an area where roots tend to avoid anyway because it is usually the first area to dry out.
Anyway, unless you have very small plants and an incredibly large infestation of them, they won't even effect your grow in the least. I stopped bothering with mine 3 crops ago and never noticed the difference (other than a few that get stuck on buds).
Other than the above suggestions, the way I used to deal with them when I bothered was to put a layer about 1/2" thick of sand on top of all my soil. The gnats eggs can't survive in the sand, and won't hatch, after 1/2 a week you should see next to none of them.

Fruit fly's do not harm your plant, I have had them around my plant for a few weeks now. They are fcking annoying but i don't see any difference

ok so all you who dont care about fungus gnats go ahead and keep them, and when you clone and they die i told you so. they are a real problem so do what you will....Adult fungus gnats are tiny black flies which spend time running around on the surfaces and sucking sap from the leaves. After the adults lay their eggs on the soil (medium), the young worm-like larvae hatch out and begin to feed upon the roots. The larvae initially eat the fine root hairs before moving on to burrow throughout the larger roots and even up into the stems. After feasting on the roots the larvae will pupate before hatching out as adults and repeating the life cycle by laying their eggs. The larvae resemble little worms. They have clear or white bodies with black heads.

Life cycle: Adults live about 7 to 10 days and deposit eggs on the moist soil surface or in soil cracks. Females lay up to 100 to 300 eggs in batches of 2 to 30 each in decaying organic matter. Eggs hatch in 4 to 6 days; larvae feed for 12 to 14 days. The pupal stage is about 5 to 6 days.

Damage from the fungus gnat larvae feeding on the roots shows up in the leaves as overfertilization and nutrient deficiency symptoms: yellowing, browning, burning and curling leaves.

well thank you all i will for sure be trying to get rid of them for every reason said above p.s. green_is_good thanks for all the life cycle info

gnat swill kill your plants for sure and will also have hundreds stuck in each bud per inch no good killum all.
