    I received some plants that had been transported in extreme freezing temperatures. They are in shock and also have a very bad gnat problem. I can;t get rid of the gnats. What can I do to try and save these plants.:sad:

    i heard soil drench and hot shot strips works good. i think you can use them mesquito dunks

    and theres also a nematode that kills them

    and your hot shots will kill off the flying ones

    the dunks and nematodes are non pesticide, cant say the same for the hot shots, from what i hear they are some nasty chemicals that are released from these things but they kill the shit out of any and all bugs in the area. if you decide to use them use cautuion and follow the labeling. also by no means is it a good idea to use them in a grow room that is maybe in a bedroom closet. especially at night.

    good luck with your gnat issue, i have had to deal with them before and they are a PITA to erradicate.

    as far as the cold weather shoock i have no clue, if the roots and medium ended up frozen solid they me be done, canabis can handle a frost or 10 as long as the medium dosent freeze.

    if things start looking really bad try and clone the whole plant if you cut it at the stem and put it under a humidity dome in some water it should perk right back up. i dont have much experience cloning an entire plant but i do know the lower part of the plant contains more hormones that are used in root development than the top of the plant so it might take to root fairly fast depending on how big this plant is.

    some pics would be great and some details on how badly it was stressed.
