A few months back, arrived back on the farm, no burn devices and a ball left from last year.
Tuna can, soldering iron, spoon, rocks glass…
Perpetual Hash Under Glass.
Carbon filters cost how much?!! Starting out I did not want to dump a lot of money into growing and thought I needed to do something about odour control. A cardboard box, small fan, landscaping fabric and a bag of BBQ briquettes that I pulverized. Also a few staples to enclose the carbon in the fabric. Actually worked. Not sure how much it can take before the carbon gets full of smells but for the length of time I needed it, it worked. Really messy breaking up the briquettes though.
I postyed this in another place some time back but what the heck. It’s a handy little greenhouse that works pretty good complete with Snap Fan powered directly by solar panel in s thermostat.
It’s made of 2 hog panels on a 2x12 frame. This pic shows the snap ties holding the two panels side by side and the pipe insulation taped arpound the connection to keep the covering from tearing.
Want to do a big hunt but don’t want to put out for 100s of containers? Make your own, out of left over Panda Poly (we’ve all got some) and a heat sealer. Modeled after the brown paper shopping bags of old. Weld with black side facing out, turn inside out, slice a few slits in the bottom and voila, cheap ass grow bag that you can also write on!
I have seen others with the same temperature/humidity displays. Dirt cheap in your local Dollar Store. I saw an interesting thing on pain management where you can train yourself by sending blood to your exterior using a temperature sensor in your hand (not really important). Knowing what I might find in the display I took it apart and unsoldered the thermistor from the board and wired it up remotely with some twisted wire (twisted wire is used to cancel out interference, not important here, just used to doing it). I put some heatshrink tubing on the leads and over the pair. It is easy enough to do remote temperature sensing (10k thermistor) but not the humidity sensor (a disappointment) The humidity sensor is 10 M (million ohms rather than thousands which the thermistor is) which might not like being too far from the board. One day I might try it though.
The board has pads etched on the back and it mates onto the back of the display. Something to keep in mind. Not bad for a $4 display. I only got it up to 67 C, went over-temp above that. Not sure where it happens as it updated the display every 5 seconds.
