    Bug Zappers in an indoor grow for fungas gnats and other fling pests?

    I had the random thought of using a bug zapper for fungus gnat control. I don't have a problem right now but things happen. The zapper would be great in a veg room but but during flowering it could only be used while the lights are on plus, maybe, 10 minutes before and after. Does anyone do...

    Decomposed granite vs granite dust - Coots Mix - In SIPs

    I am trying to buy basalt or granite rock dust locally but can't find it (near Sacramento, CA), sounds like it should be easy to find but I'm striking out. I can find decomposed granite very easily, at the same place as the lava rock for cheap but I am not sure if it will work the same as rock...

    How I hooked up PWM singals to ACInfinity Cloudline T6 and Hyperfan 8" from an Open source Software

    I thought I would share this info for the RUI comunity. For literally a couple of dollars I am able to control both T6 and Hyperfan Gen 1 8" independently. This is easily done by "intercepting" the PWM signal to the fans. Check the pictures to see how stupid simple this is. For the hyper fan...

    Adjusting light intesity in later weeks of flower (less light)

    Got a question about doing a second trellis, I feel as though my Napali Pink is going to need some healthy support, especially since she now is a 4+ footer, 32" without support. I am thinking about adding another wire screen about 20" above the first, if you look at the pictures you can see...

    Exhaust for 2 rooms?

    I am trying to figure out how to exhaust two rooms (roughly 10'x10'x9') as to not cause any problems and limit customization. Getting the vent into the attic is the easiest part, getting it out is a little bit more of a challenge since I have a tile roof. If it was a shingle roof I would think...
