It's been a year since I started this build, so this wil be a kind of retrospektiv diary.
It's really silly of me to try to grow since I don't consume more than one or two times a month, but since this is prohibition land I can not get good safe products. And it's something I did way back in the days and really enjoyed doing.
The only place I can grow is in the basement and it gets quite cold in the winter. Down to 10°c removed link So I figured I needed a insulated "tent". I also wanted it to look stealthy, and except for the extraction fan on top it still looks like a fridge. The metal casing helps to suppress noise and the magnetic door is air/smell proof.
Thats badass mate i need a weed fridge in my kitchen now 🤣 😎
Here it is up and running with a tomatoes plant.
Awesome build mate
I put 4 holes in the rim of the pot for stakes and attached a metal screen with 1.5inch squares to them for scroging. That way i could slide the screen a little up and down while tucking and I could take the whole assembly out and work on all sides.
I already had co2 equipment so I set it up with a ink bird controller and ran approximately 1000ppm.
Here are some more details:
Reptile radiator sits off the floor on DIY feet.
The backside of the fridge with rubber grommet for routing wires through.
Inside it is sealed with play doh.
I had some issues with the AC infinity controller running the lights and bought a vivosun growhub for this instead. Here is the left side of the fridge with all the tech stuff.
Still not finished describing all the technical stuff yet. This growbox turned out so incredibly well, and the environment was just about perfect. I'll write some on the actual growing later.
Initially i removed to much insulation and had to put some back on. For this i used 6mm styrofoam for use under flooring. I glued it on piece by piece and tested how the temperature was regulating. This fine tuning was key to environment control.
When the fridge ran as it should the extraction would kick in every 2-4 minutes for perhaps 30 seconds at level 4. And only be triggered by high humidity. If triggered by temperature the fan would run for longer and environmental parameters swing more. It was so stable that i could have less than 1 degree farenheit and about 6% humidity swing over 8 HOURS on a normal day (as long as I didn't open the door). When everything was humming along you could se these repeating undulating patterns in the graphs in the app showing humidity swings. Repeating approximately every 20minutes (this varied a little). It was like seeing the breathing pattern of the plants

It been over a month since I planted this tomato plant into this larger pot and it has not been feed any other nitrogen than what is in my bokashi run-off. I've kept it going just to keep learning to dial in the 9" blumat.
New, bigger pot gave it a good growth spurt, but now it's looking like the season is ending
