Thanks @chris_barfield Chris.
The cheapo thermometer you see is off several degrees in true temp, but within 4 degrees of rH. It’s only in there for rH readings. The exhaust fan (top left) has a closer to accurate temp and rH sensor. It’s harder to see when the light is on though and difficult to see with the camera due to position (gotta fix that). Temps with lights on (18” 80/83 degrees) when running the co2 the temps are only slightly higher when I kill all of the fans (4 pole fans and floor fan).
When the 4 pole fans are on low, the floor fan on low and the outage fan set at 6 of 10 the temps throughout are 78 degrees with the humidity of 70-80%. Because the LED does not push a lot of heat I struggle to get the temps much higher than very low 80’s. I do agree that ideally the temps would be higher in general and especially when the co2 is engaged. I shot you a PM in regards to your thoughts on a secondary light like a reflector, when you have a minute, thanks. Since I run AC 3/4ths of the year I’m open to suggestions on how to raise temps in the tent.
This sensor is near the top of the tent (inside)
That DIY co2 generator
Mix
2-3 cups of sugar
1 tablespoon of baking soda
1/4th gallon of water
Shake well
Now add 3-6 tablespoons of instant dry yeast shake again. Takes about 15 minutes for the co2 to build up and start pushing into the second and third chambers. Adding some Kellogg’s corn flakes will lessen the smell and provides additional food for the yeast.
Works for about 24 hours doubling the co2 in the tent directly below the tube to roughly 3200-3400 ppm - shake the milk gallon halfway through the day to jump start the reaction again. Thoroughly clean after each use.
