<span class="link_user">@Lazuli</span>, I've also found a product called purecrop 1 to control mold. I had very bad pm on my outdoor, used the pure crop twice and it pretty much went away
<span class="link_user">@Lazuli</span>, did use. Dehumidifier as it was making room way too hot but it was winter and very dry outside the grow room so I cranked the exhaust and that really helped
