Well, finally got my koji box installed in .. the basement. That was what I was trying to avoid the entire time, with the nice finish and all . It is a box after all.
On the bottom I have a 2x1 fermwrap taped down, with a turkey pan filled with pearlite and some water. It's plugged into an internal power strip, on second thought the power strip may have been a stupid idea.
I have a 200watt ceramic heater (either on or off) connected to a temp controller. Half of the box gets to 104 in 5 minutes. I adjusted the heater from blowing up to blowing across the bottom on a bottom shelf. I will need to install small fans to take air from above and shoot it down to maintain a constant heat.
I could prob. take out the fermwrap heater, but the 200watt heats up the box quite well. I think for fun I will attempt 115F.
I have cooler temps on the bottom with condensation. I need much less water
I seals up quite well. I have some picks. Gonna steam some rice tonight and start a batch to see what happens.
Probably taste like pine
