  1. Hi all,
    My friend has a somewhat large vertical hydroponic grow room. His biggest problem with this type of grow is powder mildew, so he has to use a sulfur burner. Once that is solve his second biggest problem are those damm spidermites !

    What effective method can he use to kill the spiders that will not react with the sulfur on the leaves. Seems that all products for spider mites ( that do work ! ) have an oil in it which is no good cause it reacts with the sulfur and burns the leaves.

    I read that some guys in this forum use 10,000ppm of co2 for like an hour. He 's a little afraid of that since everyone he's talked to in the different hydro store strongly suggest him not to do that

    Any other Ideas ???????

    Thanks
