Have 75 blueberry seeeds in 1 liter coco pots, and today i noticed larva in the coco around the seeds, the ones that have not hatched, dont understand how this could have happend all of them recieved equal amount of water, and have only been in coco for 5 days, been waterd once since the first water on day one.
Gold label super mix coco is the label, i love it, it has some NPK in it, enough for 3 days.

Have gnats in other plants, in the house, 3 mothers, and had a massive attack in one aero system a month back, that was successfuly treated.
Where are this suckers coming from?

where i live it is currently minus all day outside , celsius. and i draw in air form the outside, my room temp is in avarage of 25. and the humidity is a steady 30. i am about to treat with hydroperoxid as well as drying out the coco pots, but is there a place i once house where this are most likely to nest?,

as i understand it they thrive in miost areas, and since it is minus outside on the attic and such . i have a hard time understandinig where they come from

Get some GNatrol WDG ordered pronto, azamax added to res will help too. THere are many threads on fungus gnats though, diluted rubbing alcohol is a good drench, and a cap of sand or perlite on top of the medium will keep them out of your medium.

Did you sterilize the mix before use?

I don't think most guys can do this, unless only growing 1-3 plants. I know it would be extremely difficult for me to sterilize 300-400 gallons of medium 4 times a year.

well, sounds like you had some living somewhere around the house, could be from the bag..

I'm not sure on hydrogen peroxide, you need gnatrol, nematodes, and a top layer, you need to make sure and wipe them out fast before you have 75 containers with gnats in them, also they feed on roots so...
