    Russet mites

    This morning I found a plant in my little ghetto veg closet that had a big nasty yellow mass of russet mites on the fan leaf petiole. I was in a hurry so I grabbed the plant and set it out on the patio and left. When I came back a few hours later to toss the plant the mass of bugs was completely...

    Soil grow pH question (fox farms)

    what’s the ideal pH when watering young plants that aren’t yet on bottle nutes? once I start feeding nutes, I usually pH to 6.0 but I’m currently just watering and relying on the nutes pre-mixed in the soil to feed the plants. Would running a more neutral pH allow for more efficient nutrient...

    Grow Room Automation with Home Assistant

    Figured I'd show you guys what I've been working on in my free time. Its a WIP but I'm happy with progress thus far. Previously I was able to remote control and monitor my lights, temperature, humidity and ventilation. It was kind of a pain though because I had to use different apps for each...

    Let’s talk power strips

    So my grow room only has one single duplex electrical socket available. Right now I’m relying on power strips and it’s making me uncomfortable. I do have a fire sprinkler system but still, the last thing I want to do is soak my entire setup in the event of a fire emergency. I’m also not sure i...

    RJ45 dimmers

    Anyone have a source for these? My strips have onboard dimmers that go from 40% to 100% in 20% intervals but I’d like to be able to dim lower/more precisely. Is there just a basic potentiometer type knob that I can plug into the 0-10v RJ45 ports or do I need to run an actual lighting controller...

    Question for those who exhaust after CO2 shutdown

    I decided to convert to a sealed room and grabbed one of these burners on Amazon. I am going to run what some call a hybrid sealed setup. I have a small extraction fan that will clear the room air after lights out and maybe 3-4 times during the day to keep things fresh. The exhaust ducting has a...

    Wye duct with electrical damper for ducting

    Does one exist? I’m going to make the switch to CO2 but would like to retain the ability to exhaust at night using the same fan and filter. I was thinking of installing a electronically switchable wye type splitter on a timer so my filter can run as a scrubber during the day and an exhaust at...

    Portable AC + Exhaust and Intake fans

    I'm pretty sure I already know the right answer for this but I just need confirmation and suggestions. Those of you that use a portable AC, do you shutdown your intake and exhaust fans when it's on? I have a 10,000 BTU unit that's exhausted outside via its own duct. 10,000BTU should be more than...

    My Pandemic Project featuring Chinese LED Strips

    I'm going to use this thread to document my first real grow. Thanks to coronavirus, I suddenly had a whole lot of extra time on my hands and needed something to keep me occupied so I didn't go stir crazy. My friends and I tried growing in an attic years and years ago back in HS and failed...
